On Tuesday, the brightest stars from across the Major Leagues will be gathered in one place at Nationals Park for the 89th MLB All-Star Game presented by Mastercard (7:30 p.m ET, FOX).
The American League and National League All-Star teams are a Who's Who of the best players in baseball. So before they all take the field for the Midsummer Classic, MLB.com is breaking down both rosters with one cool fact for every 2018 All-Star.
Players marked with a * are inactive for the game
:: Complete All-Star Game coverage ::
C: Wilson Ramos, Rays *
Fan-elected starter; replaced by Salvador Perez
Ramos has been behind the plate for three no-hitters, all with the Nationals -- Jordan Zimmermann's in 2014 and Max Scherzer's two in '15. That puts Ramos one shy of the MLB record of four no-hitters caught, shared by Carlos Ruiz and Jason Varitek.
C: Salvador Perez, Royals
Perez will make his fifth straight All-Star Game start behind the plate for the AL. The only Royals player with more consecutive All-Star starts than Salvy is Hall of Famer George Brett, with nine.
1B: Jose Abreu, White Sox
Abreu ranks seventh in the Majors in games played (707) since his career began in 2014. Only 10 players in MLB history hit more home runs over their first four MLB seasons than Abreu, who knocked 124 from 2014-17.
Video: KC@CWS: Abreu's 451-foot HR leaves bat at 110.6 mph
2B: Jose Altuve, Astros
If he reaches the 200-hit mark this year, Altuve would become just the sixth player since 1901 to do that in five consecutive seasons, and the fourth in the past 80 years -- joining Ichiro Suzuki, Wade Boggs and Michael Young. If Altuve holds on to the AL lead in hits, he would join Ichiro as the only players to lead either the AL or NL in that category five times in a row.
3B: Jose Ramirez, Indians
Ramirez is tied for the Major League lead with 29 home runs at the All-Star break -- the third-most for a third baseman at the break behind Matt Williams in 1994 (33) and Mike Schmidt in '79 (31). Ramirez and Francisco Lindor, who has 25 homers, are the first pair of teammates aged 25 or younger with 25-plus homers in the first half of a season in MLB history.

SS: Manny Machado, Orioles
Machado led MLB with three walk-off home runs in 2017, becoming the third player to smack a walk-off grand slam to cap off a three-homer game when he accomplished that feat against the Angels on Aug. 18. Machado is one of two players, along with the Mets' Wilmer Flores, to have four walk-off homers since the beginning of '15.
OF: Mookie Betts, Red Sox
Betts is already one of just 17 players to have four or more three-homer games in his career. With his fourth (and second of the year) on May 2 against the Royals, Betts broke a tie with Ted Williams for the most in Red Sox history. He's also the first player in MLB history to have four three-homer performances before turning 26.
Video: Must C Crushed: Betts concludes 13-pitch AB with slam
OF: Aaron Judge, Yankees
En route to setting the MLB rookie record with 52 home runs last season, Judge hit the hardest homer ever tracked by Statcast™ on June 10 against the Orioles, a 121.1-mph missile at Yankee Stadium. In fact, Judge owns five of the 10 hardest homers since 2015 -- with teammate Giancarlo Stanton occupying the other five.
OF: Mike Trout, Angels
Trout's 61.0 career Wins Above Replacement, according to Baseball-Reference.com, puts him in rare territory. Trout is on the verge of passing Mickey Mantle (61.4) and Ty Cobb (63.4) for the highest WAR in baseball history by a position player through his age-26 season.
Video: Trout bats .300, clubs 2 doubles last week
DH: J.D. Martinez, Red Sox
Martinez's 29 home runs at the break give him a share of the MLB lead. The key for J.D. is his opposite-field power. Martinez's 13 opposite-field home runs this year are the most in the Majors, and his 53 since the beginning of 2015 are 18 more than second-place Joey Votto.
C: Willson Contreras, Cubs
Contreras crushed a 491-foot home run at Wrigley Field in Game 4 of the 2017 NL Championship Series against the Dodgers, the longest home run in postseason play since Statcast™ began tracking in '15. It's also tied for the eighth-longest home run overall in MLB since '15, regular season or playoffs.
Video: 3 Cubs named to 2018 NL All-Star team
1B: Freddie Freeman, Braves
Freeman enters the All-Star break with a .315/.405/.533 slash line, his third straight season in the .300/.400/.500 club. Freeman and Trout are the only qualified hitters in baseball with a batting average of at least .300, on-base percentage of at least .400 and slugging percentage of at least .500 in each of the past three seasons.
2B: Javier Baez, Cubs
No stranger to daring plays, Baez stole home for the fourth time in his career (regular-season only) on July 4 against the Tigers. That ties him with Hall of Famer Ryne Sandberg for the most by any Cubs player on record since 1974. But Baez also stole home in Game 1 of the 2016 NLCS, becoming the first Cub to swipe home plate in postseason play since Jimmy Slagle in Game 4 of the 1907 World Series.
3B: Nolan Arenado, Rockies
Arenado finished the 2017 season with 130 RBIs, marking the third consecutive season in which he drove in at least 130 runs. In doing so, Arenado became only the 11th player to reach that RBI plateau in three straight years -- and the first since Ryan Howard did so in four straight seasons from 2006-09.
SS: Brandon Crawford, Giants
The ever-steady Crawford collected his third consecutive Gold Glove Award at shortstop last fall. If he wins again this year, he'd become the first MLB shortstop to win at least four straight Gold Gloves since Omar Vizquel (nine straight from 1993-2001) and the first NL shortstop since Ozzie Smith (13 straight from 1980-92).
Video: Crawford, Posey earn spots in 2018 All-Star Game
OF: Nick Markakis, Braves
Markakis, 34, became the embodiment of the adage "better late than never" this month, when he was named to his first All-Star Game after playing in 1,928 regular-season games. Markakis' selection ended the longest wait by games played of any Major Leaguer in history prior to his first invitation to the Midsummer Classic.
OF: Matt Kemp, Dodgers
A clear front-runner for the NL's Comeback Player of the Year Award, Kemp is set to make his first All-Star Game start since 2011 -- the year he finished runner-up in the NL MVP Award vote. The last player to go at least seven years between starts in the Midsummer Classic was Aramis Ramirez, who went nine years between starts from 2005-14.
OF: Bryce Harper, Nationals
Washington's hometown superstar became the youngest player to be selected to an All-Star Game when he earned the nod at age 19 in 2012. Three seasons later, Harper became the youngest player to ever unanimously win an MVP award.
Video: WSH@NYM: Harper drives a 2-run homer to right field
RHP: Trevor Bauer, Indians
Bauer has reached the 100-pitch mark in all 20 of his starts this season. No other pitcher has done that more than 17 times (Scherzer). Those pitches are going to good use. Bauer has eight games with 10 or more strikeouts; only Scherzer and Chris Sale have more.
RHP: Jose Berrios, Twins
Berrios has made an MLB-high six starts this season in which he's completed at least seven innings while allowing no more than three hits. He's also one of just three pitchers with multiple complete games (including one shutout), along with James Paxton and Carlos Carrasco.
Video: KC@MIN: Berrios K's 8, goes 7 innings of 1-run ball
LHP: Aroldis Chapman, Yankees *
Since the start of 2015, Chapman has thrown 1,541 pitches of 100 mph or faster. That's nearly 1,200 more than any other pitcher and represents roughly one-third of the MLB total during that time. He's one of only two pitchers, along with Jordan Hicks, to break the 105-mph mark.
RHP: Gerrit Cole, Astros
Cole has made six starts this season in which he has struck out at least 10 batters. He had six such outings total with the Pirates from 2013-17. Cole's 177 strikeouts are by far his highest career first-half total -- his previous high was 116 in his All-Star '15 season.
Video: DET@HOU: Cole strikes out 8, records 10th win of year
RHP: Edwin Diaz, Mariners
Diaz has piled up an incredible 36 saves, two more than he had all of last season. It's the second-highest save total for a player before the All-Star break, passing John Smoltz (34 in 2003) and behind only Francisco Rodriguez (38 in 2008).
LHP: J.A. Happ, Blue Jays
The Toronto southpaw throws one of the primary fastball types (four-seamer, two-seamer or sinker) nearly three-quarters of the time. His 74.4 percent fastball-usage rate is the third highest this season among 133 pitchers who have thrown at least 1,000 total pitches.
Video: Gibbons on Happ's 1st career All-Star selection
RHP: Joe Jimenez, Tigers
Jimenez was named the Tigers' Minor League Pitcher of the Year in both 2015 and '16 before blossoming with the big league club this season. He won a silver medal in the '17 World Baseball Classic as a member of Team Puerto Rico.
RHP: Craig Kimbrel, Red Sox
Kimbrel's career save percentage of 91.2 percent is the second-best all-time among qualifying relievers, behind only Eric Gagne's 91.7 percent mark. Kimbrel reached the 300-save milestone on May 5 this season, becoming the fastest pitcher to the milestone by career games (494) and save opportunities (330), as well as the youngest by age (29 years, 342 days).
RHP: Corey Kluber, Indians *
When Kluber won the AL Cy Young Award last year, he became the first pitcher to win multiple AL Cy Young Awards in Indians franchise history, and the 19th in Major League history. (Kluber also won the award in 2014.) Before Kluber, the last pitcher to win multiple AL Cy Young Awards was Johan Santana for the Twins in 2004 and '06.
RHP: Charlie Morton, Astros
Morton was the winning pitcher in Game 7 of last year's World Series after pitching the final four innings to close out the Dodgers. It was the longest relief outing to win the deciding game of the Fall Classic since the Yankees' Bud Daley went 6 2/3 to finish off the 1961 World Series.
LHP: Chris Sale, Red Sox
Sale has a Major League-leading 188 strikeouts at the All-Star break, and he led MLB in strikeouts last year, too, with 308. That marked the first 300-strikeout season by an AL pitcher since 1999, when Sale's Red Sox predecessor Pedro Martinez had 313.
RHP: Luis Severino, Yankees
Since the beginning of his breakout 2017 season, Severino has thrown 32 pitches 100 mph or harder. That's by far the most of any starting pitcher in that time span -- Noah Syndergaard is next with 17 pitches in triple digits. Severino accounts for more than a third of the total 100-plus mph pitches thrown by MLB starters since the start of '17.
Video: Four Yankees named to 2018 AL All-Star team
LHP: Blake Snell, Rays
Snell's breakout 2018 season has featured plenty of dominant moments, perhaps none more so than his June 3 start against his hometown team, the Mariners. The southpaw struck out the first seven batters he faced in that outing, tying Joe Cowley (1986) and Carlos Rodon ('16) for the AL record.
RHP: Blake Treinen, Athletics
Treinen leads all qualifying MLB relievers this season with a 0.94 ERA, and he's struck out 61 batters in his 48 innings. He's just the third pitcher since the All-Star Game began in 1933 to have an ERA under 1.00 and more than 60 strikeouts heading into the Midsummer Classic, along with Ernesto Frieri (2012) and Robb Nen ('98).
Video: OAK@SF: Treinen fans the side to preserve the win
RHP: Justin Verlander, Astros *
Since Verlander joined the Astros at the beginning of last September, he has a 2.04 ERA in his 26 starts (not including his dominant postseason, when he had a 2.21 ERA en route to Houston's World Series championship). That ERA is the best in the Majors over that time span, among the 160 pitchers who have made at least 10 starts. Verlander's 215 strikeouts are also fourth most of any pitcher since last Sept. 1.
LHP: Patrick Corbin, D-backs
Corbin has gotten opposing hitters to miss on 33.4 percent of their swings against him this year, which ranks third among the 69 starters who've generated at least 750 total swings, behind only Sale and Scherzer. His slider has been especially good -- he has 212 swinging strikes on that pitch alone, 85 more than the next-closest pitcher, Severino (127).
RHP: Jacob deGrom, Mets
The Major Leagues' ERA leader (1.68) has held opponents to one earned run or fewer in 14 starts this year, the most of any big league pitcher. Those 14 such starts are also the most recorded by any pitcher before the All-Star break in the history of the Mets franchise.
Video: PHI@NYM: deGrom strikes out 7 over 8 shutout innings
LHP: Sean Doolittle, Nationals *
Doolittle has been incredibly stifling over the season's first half, permitting a microscopic 0.54 WHIP. That is the the second-lowest WHIP recorded by any pitcher with at least 30 innings before the All-Star break, behind the 0.50 WHIP logged by Boston's Kimbrel last year.
RHP: Mike Foltynewicz, Braves
Folty's average fastball velocity of 96.5 mph ranks right behind Severino, Syndergaard, Nathan Eovaldi and Shohei Ohtani for the highest among regular starting pitchers. But his secondary stuff has been even better: Opponents have hit just .124 against his breaking and offspeed pitches, which is the lowest batting average allowed among starters who have ended at least 150 at-bats with a secondary pitch.
Video: 4 Braves named to the 2018 All-Star team
RHP: Zack Greinke, D-backs
Greinke does it all. He's coming off his fourth consecutive Gold Glove Award in 2017, becoming the 10th pitcher in history to capture the defensive honor in four straight campaigns. And this season, Greinke has stolen three bases as a runner -- making him the first pitcher with three steals in a season since Tom Browning in 1998.
LHP: Josh Hader, Brewers
Milwaukee's dynamite reliever has struck out more than half of the batters he's faced in 2018: 50.3 percent. Only two pitchers in MLB history with at least 50 innings pitched in a season -- Hader's fellow All-Stars Chapman (52.5 percent in '14) and Kimbrel (50.2 percent in '12) -- have had a strikeout rate over 50 percent.
LHP: Brad Hand, Padres
Opponents have hit just .126 (28-for-222) against Hand's slider since the start of last season, the lowest batting average allowed by any hurler who has ended at least 150 at-bats on that pitch in that span. Over half of those at-bats, 123, have been strikeouts.
Video: Hand earns a spot in the 2018 All-Star Game
RHP: Kenley Jansen, Dodgers
Jansen owns a career WHIP of 0.88, which is the lowest of any pitcher who has thrown at least 500 innings in the Live Ball Era. His career 2.10 ERA is second only to Kimbrel in that nearly century-long span.
RHP: Jeremy Jeffress, Brewers
Jeffress finished his first half with a 1.34 ERA, tied with Hall of Famer Rollie Fingers in 1981 for the lowest first-half ERA by any Brewers pitcher with at least 40 innings pitched at the break.
LHP: Jon Lester, Cubs *
The Cubs' veteran ace has appeared in 25 total postseason games (including 21 starts) and recorded a stellar 2.55 ERA in those high-pressure contests. That ERA is tied for Orlando Hernandez for ninth best among pitchers who have made at least 10 career playoff starts.
RHP: Miles Mikolas, Cardinals *
Mikolas pitched three seasons for the Yomiuri Giants of Japan's Nippon Professional Baseball, recording a 2.18 ERA over 62 starts from 2015-17. He has been just as impressive in his return to the U.S. this year, putting together a 2.79 ERA that ranks sixth among qualified NL starters.
RHP: Aaron Nola, Phillies
Nola is blossoming into one of the Senior Circuit's premier aces. He goes into the break having allowed the lowest slugging percentage among qualified starters (.278), as well as an NL-low 0.4 home runs per nine innings. He's also second to deGrom in the NL in ERA (2.30).
Video: PHI@MIA: Nola picks up his 500th career strikeout
RHP: Max Scherzer: Nationals
Scherzer has a chance at a third consecutive NL Cy Young Award, which would make him just the third pitcher to claim the NL award three straight times after Hall of Famers Greg Maddux and Randy Johnson. Having also won the award in the AL with the Tigers, he's already one of just 10 pitchers in Major League history with three total Cy Young Awards.
RHP: Ross Stripling, Dodgers
Stripling has been a revelation for L.A. since moving to the rotation, helping the Dodgers stay in the hunt amid a slew of injuries to the club's rotation. The righty enters his first All-Star Game with a 7.71 strikeout-to-walk ratio that's the best among NL starters.
LHP: Felipe Vazquez, Pirates
Pittsburgh's closer has an average fastball velocity of 97.3 mph this season, ranking third among left-handers behind only Chapman and Jose Alvarado. And Chapman is the only lefty who's thrown more pitches 100-plus mph than Vazquez's 17.
Video: MIL@PIT: Vazquez earns 22nd and 23rd saves in 1 day
C: Yan Gomes, Indians
Gomes has been one of MLB's most consistent arms behind the plate, finishing in the AL's top five in caught-stealing percentage on three occasions (2013, '14 and '17). He is also the first Brazilian-born player to be selected to an All-Star team.
1B: Mitch Moreland, Red Sox
Moreland earned his first All-Star selection at age 32 on the strength of his hitting, but he very nearly wasn't a full-time hitter at all. In 2008, the Rangers' front office asked Moreland to switch to pitching based in part on his mound success at Mississippi State, but Moreland asked for one more season to prove himself as a position player. The rest is history.
2B: Gleyber Torres, Yankees *
Torres wasn't known for his power in the Minors, but it became immediately apparent once he arrived in the Bronx. Torres homered in his four consecutive games from May 21-25, becoming the youngest player in AL history to do so. He has 15 home runs at the break; Mickey Mantle and Joe DiMaggio are the only Yankees who hit more before their 22nd birthday.
2B: Jed Lowrie, Athletics
Lowrie set an A's franchise record with 49 doubles in 2017, also becoming one of seven players in team history to record multiple seasons with at least 40 two-baggers. The key: tons of line drives. No player in baseball hit more than Lowrie last year (161).
Video: OAK@CLE: Lowrie drills solo HR for 100th hit of 2018
3B: Alex Bregman, Astros
Bregman captured the AL Player of the Month Award this past June after hitting .306 and slugging .713 during the month. He also set an Astros franchise record for the month of June by driving in 30 runs.
SS: Francisco Lindor, Indians
Lindor's extraordinary power for a shortstop shone on both May 12 and June 1 of this year -- he homered twice and doubled twice in both of those games. Only three players before Lindor -- Rafael Palmeiro (1993), Jim Edmonds (2003) and Adrian Beltre ('07) -- had recorded two games in a season with both multiple home runs and at least four extra-base hits.
SS: Jean Segura, Mariners
Segura enters the All-Star break with 480 hits since the start of the 2016 season, a total topped only by fellow All-Stars Altuve, Charlie Blackmon and Betts in that span. His .313 batting average since '16 ranks sixth in the Majors.
Video: Dipoto discusses Segura's ASG nod on The Wheelhouse
OF: Michael Brantley, Indians
When Brantley sees a pitch he likes, he rarely misses. He made contact on 94.5 percent of his swings against pitches in the strike zone over the first half, tied for the best of over 200 players who swung at least 300 times at in-zone pitches.
OF: Shin-Soo Choo, Rangers
Choo might not want to take a break from regular-season action considering the hot streak he's on. The Rangers outfielder has reached base in 51 straight games, the longest streak by any player since Kevin Millar's 52-game stretch back in 2007.
Video: TEX@BAL: Choo walks, on-base streak extends to 51
OF: Mitch Haniger, Mariners
Haniger has been as rock solid in the field as he has at the plate. His nine outfield assists in the first half tied Tigers center fielder Leonys Martin for the AL lead, and his 192 putouts lead all MLB right fielders.
OF: George Springer, Astros
Springer started the Astros' 2017 World Series run with a leadoff home run on Opening Day, and he kicked off their '18 title defense with another -- becoming the first player in MLB history to hit a leadoff home run on back-to-back Opening Days.
Video: Six Astros named to 2018 AL All-Star team
OF: Nelson Cruz, Mariners
Cruz has belted 188 homers since the beginning of the 2014 season, 13 more than any other player in baseball in that span (Edwin Encarnacion is second with 175).
C: Yadier Molina, Cardinals
In March, Molina suited up for his 14th consecutive Opening Day behind the plate for St. Louis, the longest active streak at any position with one team in the Majors. A few months later, on June 18, Yadi caught his 1,757th career game with the Cardinals -- passing Gabby Hartnett for the most games caught with a single franchise.
C: Buster Posey, Giants *
Posey's career .307 batting average is tied for sixth all-time (with Joe Mauer) among the group of over 200 players who logged at least 3,000 plate appearances and played catcher as their primary position. In 2012, Posey hit .336 to become the first backstop to win the NL batting title since Hall of Famer Ernie Lombardi in 1942.
C: J.T. Realmuto, Marlins
Realmuto is the Majors' fastest catcher by Statcast™'s sprint speed metric, averaging 28.6 feet per second on max-effort runs. That's not just good for a catcher; it's solidly within the top 20 percent of all Major League players, and well above the MLB average of 27 feet per second.
Video: Realmuto to represent Marlins at 2018 All-Star Game
1B: Jesus Aguilar, Brewers
Aguilar fought to be one of the last men on the Brewers' roster when Spring Training came to a close. Now, Aguilar enters the All-Star break leading the NL in home runs (24), slugging percentage (.621) and OPS (.995).
1B: Paul Goldschmidt, D-backs
"America's First Baseman" has been on an absolute tear after an uncharacteristically slow start which saw his batting average below the Mendoza Line as late as May 22. Since the calendar flipped to June, no Major Leaguer with at least 100 plate appearances tops Goldschmidt's .369 average and 1.166 OPS.
1B: Joey Votto, Reds
Votto reached base 321 times last year, a Reds franchise record and the highest single-season total by any Major Leaguer since Barry Bonds in 2004. Votto's career .428 OBP ranks among the top 10 marks all-time among players with at least 5,000 plate appearances.
2B: Ozzie Albies, Braves
The 5-foot-8, 165-pound Albies enters the break with 52 extra-base hits, which ties Trout's 2013 total for the most extra-base hits before the All-Star Game by any player in his age-21 season or younger.
2B: Scooter Gennett, Reds
Gennett leads all NL second baseman with 43 home runs since the start of the 2017 season, including four in one game on June 6 of last year. He's one of 18 players in Major League history with a four-homer game.
Video: Votto, Gennett, Suarez make 2018 All-Star Game
3B: Eugenio Suarez, Reds
Suarez has 71 RBIs this season, just one behind fellow All-Star Baez for the NL lead. He could become the first Reds player to lead the league in RBIs since Dave Parker back in 1985.
SS: Trevor Story, Rockies
On Opening Day 2016, Story became just the seventh player to hit two home runs in his Major League debut (and the first in a season opener). Story soon set a record with seven homers in his first six MLB games, and went on to tie a rookie record with 10 homers in the month of April.
Video: Story shows off all 5 of his tools on the field
OF: Charlie Blackmon, Rockies
Last season, Blackmon became the first player to lead the Major Leagues in hits (213), runs (137), triples (14) and total bases (387). He also won the NL batting title with a .331 average, and he had a record 103 RBIs from the leadoff spot.
OF: Lorenzo Cain, Brewers
Cain is one of the best defensive outfielders in the game. His +36 Outs Above Average (Statcast™'s range-based metric to grade outfield defense) is fifth best among outfielders since the start of 2016. Only Ender Inciarte, Billy Hamilton, Byron Buxton and Betts have higher marks. Cain's +10 OAA in 2018 alone is tied for fifth best in MLB at the All-Star break.
Video: MIL@PIT: Statcast™ tracks Cain's doubleheader defense
OF: Christian Yelich, Brewers
Yelich had the highest hard-hit rate in the NL in the first half -- 52.3 percent of his batted balls exceeded Statcast™'s 95-mph exit velocity threshold for hard contact. Since Yeli's breakout 2016, his 560 hard-hit balls are third most of any hitter, behind Machado and Betts.
