The Rookie of the Year Award is baseball's annual glimpse into the future, designating impressive youngsters who could go on to significantly impact baseball in the years to come. Many have gone on to enjoy multiple All-Star seasons and Hall of Fame induction ceremonies, while others ultimately fell short of the promise they originally displayed.
The future is uncertain, but with some hindsight and time, we can look back and appreciate just how good many of these rookies were. Some fundamentally changed the sport with new approaches, outstanding courage or just awe-inspiring talent. Others came from out of nowhere to be linchpins for championship clubs. The point is, the Rookie of the Year is an exciting award in the moment, but it's also just as fun to look back and see how legends began.
That's what we're doing below, with a ranking of each and every Baseball Writers' Association of America (BBWAA) Rookie of the Year Winner dating back to the first national honor, given to Jackie Robinson, way back in 1947.
• Ranking every MVP | Ranking every Cy Young
First, a quick look into our process: We compiled each winner's average Wins Above Replacement (WAR) totals from three main sources (Baseball-Reference, Fangraphs and Baseball Prospectus) to begin with a loose "ranking." From there, players were sorted subjectively based on their statistics, contributions to their team and their historical impact on the game as a whole. And the key word here is subjective as no one is likely to agree on a ranking of 148 names, but we did our best here to create an accurate picture of the cream of the crop through history. (For 2020, the effects of a 60-game schedule due to the coronavirus pandemic were taken into consideration for those winners' rankings).
(Note: Runners-up are listed in all years except in occasional instances where the winner was unanimous and no second-place finisher was named.)
Here are the rankings, from Nos. 1 to 148:
1. Jackie Robinson, 1947 NL (Dodgers)
Key stats: .297 BA, 29 SB, 31 2B
Robinson's rookie campaign resonates beyond statistics, as he had to endure substantially more than any other freshman in history. Robinson's courage changed baseball forever, opening up opportunities to countless players from all walks of life. But Robinson certainly earned his Rookie of the Year Award, too, drawing twice as many walks as strikeouts, batting nearly .300 and leading the NL in steals while playing a central role for a pennant-winning Dodgers club.
Runner-up: Larry Jansen, NYG (21-5, 3.16 ERA)
2. Ichiro Suzuki, 2001 AL (Mariners)
Key stats: .350 BA, 242 H, 56 SB
Ichiro's 242 hits as a rookie still stand as the 10th-highest single-season total in history, and his .350 average is the highest by any post-Integration rookie. But Ichiro was more than an extremely skilled hitter; his speed (an MLB-most 56 steals) and cannon arm from right field made him a phenom -- and an MVP. Plus, he did it all in a new country, resetting Americans' expectations for Japanese-born players.
Runner-up: CC Sabathia, CLE (17-5, 4.39 ERA)
3. Mike Trout, 2012 AL (Angels)
Key stats: 30 HR, 49 SB, .963 OPS (168 OPS+)
The advanced metrics say Trout is the best rookie ever by a wide margin, and it was clear early in the 2012 season that the 20-year-old could be a generational talent -- if not more than that. Trout brought power, speed (he went 49-for-54 on steal attempts) and defense at a premium position, establishing himself as one of the game's most well-rounded players. Not bad for a player who began that season in Triple-A, and wasn't even the most anticipated rookie in Spring Training.
Runner-up: Yoenis Céspedes, OAK (23 HR, 82 RBI)
4. Fred Lynn, 1975 AL (Red Sox)
Key stats: .331 BA, .967 OPS (162 OPS+), 47 doubles
The other rookie to claim a league MVP alongside Ichiro, Lynn helped elevate the Red Sox to pennant winners with his dazzling all-around game. The 23-year-old paced the AL with a .566 slugging percentage, 47 doubles and 103 runs scored and finished second to Rod Carew in the batting race, while also displaying some of the best center-field defense ever played at Fenway Park.
Runner-up: Jim Rice, BOS (22 HR, 102 RBI)
5. Aaron Judge, 2017 AL (Yankees)
Key stats: 52 HR, 127 BB, 128 runs, 1.049 OPS (171 OPS+)
When you break the rookie home run record while also leading your league in runs and walks, you're going to land somewhere near the top of this list. Judge shattered Joe DiMaggio's homer record for Yankees freshmen and rewrote expectations for what a 6-foot-7 player could do -- and for what we could expect from Statcast™ exit velocity readings.
Runner-up: Andrew Benintendi, BOS (20 HR, 90 RBI)
6. Albert Pujols, 2001 NL (Cardinals)
Key stats: .329 BA, 37 HR, 130 RBI, 1.013 OPS (157 OPS+)
Pujols had to wait until the 13th round of the 1999 Draft to hear his name, and had to impress the Cardinals' brass in Spring Training two years later to make the big league roster. By June, Pujols already had 20 homers and was clearly one of the NL's best overall hitters. His 130 RBIs are an NL rookie record.
Runner-up: Roy Oswalt, HOU (14-3, 2.73 ERA)
7. Dwight Gooden, 1984 NL (Mets)_
Key stats: 17 wins, 2.60 ERA (137 ERA+), 276 SO_
Flashing the most potential of any rookie pitcher since Bob Feller, Gooden took baseball by storm in '84. His 276 strikeouts shattered Herb Score's previous rookie record of 245, but his peripherals were arguably even more impressive; at 19 years of age, "Doc" paced the Majors in FIP (1.69), WHIP (1.07) and hits per nine innings (6.6). When he was on, he appeared untouchable.
Runner-up: Juan Samuel, PHI (15 HR, 69 RBI)
8. Pete Alonso, 2019 NL (Mets)
Key stats: 53 HR, 120 RBI, .583 SLG, .941 OPS (148 OPS+)
The Mets bucked against recent industry trends and started their rookie slugger on Opening Day despite service-time considerations, and Alonso rewarded their faith with a historic campaign. The first baseman broke Aaron Judge’s rookie home run record while also becoming the first freshman to win the Majors’ homer crown outright. On his way there, the “Polar Bear” quickly became a folk hero and team leader in Queens.
Runner-up: Mike Soroka, ATL (13-4, 169 ERA+)
9. Mark McGwire, 1987 AL (Athletics)
Key stats: 49 HR, 118 RBI, .618 SLG, .987 OPS (164 OPS+)
McGwire would likely have been higher on this list before Judge broke his rookie home run record, but Big Mac's power numbers at age 23 still astound. His .618 slugging percentage led the Majors, and his 344 total bases were second-most in the AL behind George Bell.
Runner-up: Kevin Seitzer, KC (.323 BA, 207 H)
10. Dick Allen, 1964 NL (Phillies)
Key stats: .939 OPS (162 OPS+), 13 3B, 125 R
Allen burst onto the scene with prodigious power, leading the Senior Circuit in runs, triples, extra-base hits and total bases while placing in the league's top five in several other major offensive categories. Allen's 8.8 bWAR remains the record for any NL rookie.
Runner-up: Rico Carty, MIL (.330 BA, 22 HR)
11. Mike Piazza, 1993 NL (Dodgers)
Key stats: 35 HR, 307 total bases, .932 OPS (153 OPS+)
Piazza raised expectations for rookie catchers, tying Rudy York's 56-year-old record for homers by a first-year backstop while also breaking York's precedent with 112 RBIs.
Runner-up: Greg McMichael, ATL (19 SV, 2.06 ERA)
12. Tony Oliva, 1964 AL (Twins)
Key stats: .323 BA, 43 2B, 374 total bases
Oliva's .328 average made him the first rookie in modern history to win a batting title, and he also paced the AL in hits, runs and doubles. His 374 total bases led the Majors and is tied with Hal Trotsky (1934) for the most by any first-year player.
Runner-up: Wally Bunker, BAL (19-5, 2.69 ERA)
13. José Abreu, 2014 AL (White Sox)
Key stats: 36 HR, .581 SLG, .964 OPS (173 OPS+)
Abreu defected from Cuba in August 2013 and took the AL by storm months later, immediately setting rookie records with 10 homers and 32 RBIs by the end of April. He finished with 36 homers, a White Sox rookie record, and an MLB-best .581 slugging percentage.
Runner-up: Matt Shoemaker, LAA (16-4, 3.04 ERA)
14. Fernando Valenzuela, 1981 NL (Dodgers)
Key stats: 8 shutouts, 180 strikeouts, 2.48 ERA
"Fernandomania" remains the most memorable storyline from the '81 season, as L.A.'s 20-year-old from Mexico rode his screwball and an MLB-most eight shutouts to become the first to win both a Rookie of the Year and Cy Young Award in the same season.
Runner-up: Tim Raines, MON (.304 BA, 71 SB)
15. Shohei Ohtani, 2018 AL (Angels)
Key stats: 22 HR, .925 OPS (152 OPS+), 63 SO in 51.2 IP
Ohtani ranked among the AL's top hitters in limited time as a designated hitter, and also showed electric stuff as a pitcher. No other Rookie of the Year winner has showcased that kind of skillset. Many wondered whether Ohtani could compete in the Majors after a tough Spring Training, but the Japanese import became the first player since Babe Ruth to pair 10 pitching appearances on the mound with 20 homers at the plate.
Runner-up: Miguel Andújar, NYY (27 HR, 47 2B)
16. Mark Fidrych, 1976 AL (Tigers)
Key stats: 19 wins, 2.34 ERA (159 ERA+), 24 complete games
Fidrych became an overnight sensation in Detroit thanks to the combination of his hair, his passion on the mound and most of all, his talent. His 24 complete games, unlikely to be matched again, are the most of any post-World War II rookie.
Runner-up: Butch Wynegar, MIN (.260 BA, 69 RBI)
17. Frank Robinson, 1956 NL (Reds)
Key stats: 38 HR, 122 R, .558 SLG
Robinson broke Wally Berger's then-rookie record with 38 round-trippers while showing little fear of National League pitchers, garnering a league-high 20 hit-by-pitches.
18. Carlton Fisk, 1972 AL (Red Sox)
Key stats: .909 OPS (162 OPS+), 22 HR, 9 3B
Fisk emerged as the rare offensive threat at catcher, leading the AL with nine triples while hitting .293 and playing Gold Glove defense behind the plate. He became the first unanimous winner of the AL Rookie of the Year.
19. Ryan Braun, 2007 NL (Brewers)
Key stats: 34 HR, 97 RBI, .634 SLG
Braun dominated NL pitchers, averaging a homer for every 13 at-bats and posting a league-best .634 slugging percentage that ranks second to Rudy York (.651 in 1937) among rookies who have logged at least 350 at-bats in a season.
Runner-up: Troy Tulowitzki, COL (.291 BA, 24 HR)
20. Corey Seager, 2016 NL (Dodgers)
Key stats: .308 BA, 71 extra-base hits, .877 OPS (134 OPS+)
Seager's 134 league-adjusted OPS+ tied the high mark for post-Integration NL rookie shortstops, and he set Los Angeles Dodgers rookie records for hits and doubles.
Runner-up: Trea Turner, WSH (.342 BA, 33 SB)
21. Hideo Nomo, 1995 NL (Dodgers)
Key stats: 236 SO, 2.54 ERA (149 ERA+), 5.8 H/9
With a forkball and a windup from another planet, Nomo made NL hitters look silly while blazing a path for Japanese stars of the future.
Runner-up: Chipper Jones, ATL (23 HR, 86 RBI)
22. Nomar Garciaparra, 1997 AL (Red Sox)
Key stats: 30 HR, 209 H, 11 3B
Garciaparra transformed power expectations for shortstops, beginning with his 30 homers and .534 slugging percentage in '97, both of which remain the standard for rookies at the position.
Runner-up: Jose Cruz, SEA/TOR (26 HR, 68 RBI)
23. Jose Fernandez, 2013 NL (Marlins)
Key stats: 2.19 ERA (176 ERA+), 187 SO, 5.8 H/9
Fernandez stuck out eight Mets in his MLB debut and later posted 14- and 13-strikeout performances in the second half as he quickly made believers out of observers across the league. His 5.8 hits per nine innings rate led all qualified Major League pitchers.
Runner-up: Yasiel Puig, LAD (.319 BA, 19 HR)
24. Walt Dropo, 1950 AL (Red Sox)
Key stats: .322 BA, 34 HR, 144 RBI
Dropo turned down offers in professional basketball and football to swing the bat for the Red Sox, and immediately showed off his athleticism. His 144 RBIs are still second to Ted Williams' 145 in 1939 among rookies.
Runner-up: Whitey Ford, NYY (9-1, 2.81 ERA)
25. Kerry Wood, 1998 NL (Cubs)
Key stats: 233 SO, 6.3 H/9, 3.40 ERA
Introducing some of the most unhittable stuff in recent memory to the NL, the 21-year-old Wood tied an MLB record with 20 strikeouts against the Astros on May 6 -- just the fifth start of his career.
Runner-up: Todd Helton, COL (.315 BA, 25 HR)
26. Orlando Cepeda, 1958 NL (Giants)
Key stats: .312 BA, 25 HR, 38 2B
Just 20 years old, Cepeda earned his "Baby Bull" moniker by leading the NL in doubles while also placing in the league's top 10 in average, slugging, homers, RBIs, runs, steals and total bases.
27. Tim Salmon, 1993 AL (Angels)
Key stats: 31 HR, 82 BB, .918 OPS (143 OPS+)
Salmon racked up 17 homers by the All-Star break, but was somehow not voted to the 1993 All-Star Game. In fact, Salmon never played in a Midsummer Classic despite three separate Top-20 finishes in AL MVP voting.
Runner-up: Jason Bere, CWS (12-5, 3.47 ERA)
28. Willie McCovey, 1959 NL (Giants)
Key stats: .354 BA, .656 SLG, 13 HR in 52 G
"Stretch" put NL pitchers on notice while compiling the smallest resume of any Rookie of the Year winner, knocking an extra-base hit once every seven at-bats.
29. Yordan Alvarez, 2019 AL (Astros)
Key stats: 1.067 OPS (173 OPS+), .655 SLG 27 HR, 78 RBI in 87 G
A truncated season kept Álvarez from appearing even higher, but the eye-popping numbers he put up made for a great modern-day impression of Willie McCovey. Álvarez ranked among the Majors’ best hitters after debuting in June, making a dangerous Astros lineup even deeper by providing serious pop in its center. The Cuban native’s 178 weighted runs created plus finished as the second-highest by any rookie with 300-plus plate appearances, trailing only Shoeless Joe Jackson in 1911.
Runner-up: John Means, BAL (12-11, 131 ERA+)
30. Gary Peters, 1963 AL (White Sox)
Key stats: 19 wins, 2.33 ERA (150 ERA+), 4 shutouts
Peters, a southpaw, paced the AL with a 2.33 ERA over 243 innings, and his 2.34 FIP in '63 suggests he earned every bit of his 19 victories.
Runner-up: Pete Ward, CWS (.295 BA, 22 HR)
31. Johnny Bench, 1968 NL (Reds)
Key stats: 244 total bases, 40 2B, 82 RBI
Ushering in a golden age of backstops alongside Fisk and Thurman Munson, Bench became the first catcher to win a Rookie of the Year Award, while also becoming the first rookie catcher to earn a Gold Glove.
Runner-up: Jerry Koosman, NYM (19-12, 2.08 ERA)
32. Tom Seaver, 1967 NL (Mets)
Key stats: 16 wins, 2.76 ERA (122 ERA+), 18 CG
Seaver remarkably won 16 games for a Mets club that lost 101, signaling that brighter times were ahead for the nascent franchise.
Runner-up: Dick Hughes, STL (16-6, 2.67 ERA)
33. John Montefusco, 1975 NL (Giants)
Key stats: 15 wins, 2.88 ERA, 215 SO
Montefusco homered in his first Major League at-bat in 1974, and then came back to lead the NL in strikeouts per nine in his first full season in '75. He would throw a no-hitter on Sept. 29, 1976, against the Braves.
Runner-up: Gary Carter, MON (.270 BA, 17 HR)
34. Buster Posey, 2010 NL (Giants)
Key stats: .305 BA, 43 extra-base hits, .862 OPS (133 OPS+)
Posey established himself as the cleanup hitter on the eventual World Series-champion Giants while also guiding the Majors' best pitching staff at age 23.
Runner-up: Jason Heyward, ATL (18 HR, 72 RBI)
35. Hanley Ramirez, 2006 NL (Marlins)
Key stats: .292 BA, 46 2B, 51 SB
The 22-year-old Ramirez arrived in Miami via a trade with the Red Sox and promptly became the fifth Major Leaguer since the turn of the century to pair 45 doubles with 50 stolen bases, joining Craig Biggio, Lou Brock, Ty Cobb and Tris Speaker.
Runner-up: Ryan Zimmerman, WSH (20 HR, 110 RBI)
36. Ronald Acuña Jr., 2018 NL (Braves)
Key stats: .293 BA, 26 HR, .917 OPS (144 OPS+)
Acuna entered the year as baseball's top position-player prospect and lived up to the hype. The 20-year-old went on a tear in the second half, becoming the youngest player on record to homer in five consecutive games during a white-hot stretch in August.
Runner-up: Juan Soto, WSH (22 HR, .923 OPS)
37. Alvin Davis, 1984 AL (Mariners)
Key stats: 27 HR, 116 RBI, .888 OPS (147 OPS+)
Davis began his career by reaching base in 47 straight games and homered in his first two big league contests. He finished '84 within the AL's top five in RBIs and on-base percentage.
Runner-up: Mark Langston, SEA (17-10, 3.40 ERA)
38. Kris Bryant, 2015 NL (Cubs)
Key stats: 26 HR, 31 2B, 99 RBI
Bryant lived up to his top-prospect billing in '15, recording two homers and six RBIs on Independence Day and later crushing a 495-foot homer at Wrigley Field while helping the Cubs capture their first postseason berth in seven years.
Runner-up: Matt Duffy, SF (.295 BA, 77 RBI)
39. Jon Matlack, 1972 NL (Mets)
Key stats: 15 wins, 2.32 ERA (145 ERA+), four shutouts
Matlack began the '72 season 6-0 with a 1.95 ERA as he emerged as the last cog of New York's "Big Three" aces beside Tom Seaver and Jerry Koosman. He'd help the "You Gotta Believe" Mets claim an improbable NL pennant one year later.
Runner-up: Dave Rader, SF (.259 BA, 41 RBI)
40. Tommie Agee, 1966 AL (White Sox)
Key stats: 22 HR, 27 2B, .773 OPS (127 OPS+)
Agee broke out as a superb two-way player at age 23, serving as the White Sox lone representative at the All-Star Game and capturing a Gold Glove award for his defense in center field.
Runner-up: Jim Nash, KCA (12-1, 2.06 ERA)
41. Herb Score, 1955 AL (Indians)
Key stats: 245 strikeouts, 16 wins, 2.85 ERA
Score's 245 punchouts stood as the rookie mark until Dwight Gooden came along, and his 16 wins and 2.85 ERA helped him hold his own in a rotation that also included Early Wynn, Bob Lemon and an aging Bob Feller.
Runner-up: Billy Klaus, BOS (.283 BA, 60 RBI)
42. Evan Longoria, 2008 AL (Rays)
Key stats: 27 HR, 85 RBI, .874 OPS (127 OPS+)
Longoria's arrival marked a transformational year for the Rays as the franchise reached its first World Series. His play impressed Tampa Bay enough to offer him a six-year contract by the middle of April.
Runner-up: Alexei Ramirez, CWS (.290 BA, 77 RBI)
43. Don Newcombe, 1949 NL (Dodgers)
Key stats: 17 wins, 3.17 ERA (130 ERA+), 5 shutouts
Newcombe was one of the first African-American pitchers to find success in the Majors, leading the Dodgers' pennant-winning staff with 17 wins and recording an NL-most five shutouts.
Runner-up: Del Crandall, BSN (.263 BA, 34 RBI in 67 G)
44. Thurman Munson, 1970 AL (Yankees)
Key stats: .302 BA, .801 OPS (126 OPS+), 33 caught stealing throws
Munson's emergence gave the Yankees a cornerstone for the rest of the 1970s, with the young catcher serving as a stalwart both at the plate and behind it.
Runner-up: Roy Foster, CLE (23 HR, 60 RBI)
45. Scott Rolen, 1997 NL (Phillies)
Key stats: 59 extra-base hits, 92 RBI, 30 double plays turned
Rolen's combination of power and stellar defense at third base made him a unanimous pick over an impressive cast of fellow rookies including Vladimir Guerrero, Livan Hernandez and Andruw Jones.
Runner-up: Livan Hernandez, FLA (9-3, 3.18 ERA)
46. Cal Ripken Jr., 1982 AL (Orioles)
Key stats: 28 HR, 93 RBI, 284 total bases
Baseball wasn't used to a shortstop of Ripken's stature, but the coach's son proved he could hit for power and hold his own at the athletically demanding position. Ripken also began his famous consecutive games played streak with a start against Toronto on May 30.
Runner-up: Kent Hrbek, MIN (23 HR, 92 RBI)
47. Bryce Harper, 2012 NL (Nationals)
Key stats: 22 HR, 26 2B, 98 R
Harper's 57 extra-base hits and 254 total bases each set records for any player before his age-20 season. He also became the youngest player to homer since Adrián Beltré in 1998.
Runner-up: Wade Miley, ARI (16-11, 3.33 ERA)
48. Craig Kimbrel, 2011 NL (Braves)
Key stats: 46 SV, 2.10 ERA, 14.8 K/9
The Braves gave Kimbrel a shot to close after a successful September callup audition in 2010, and he proceeded to set an MLB rookie record for saves. Kimbrel reached 100 career strikeouts in just 59 1/3 innings and strung together a 38 1/3 scoreless innings streak from mid-June through early September.
Runner-up: Freddie Freeman, ATL (21 HR, 76 RBI)
49. Cody Bellinger, 2017 NL (Dodgers)
Key stats: 39 HR, 97 RBI, .581 SLG
Bellinger became the first rookie to hit 10 homers in a 10-game span, hit for the cycle on July 15 and broke the NL rookie record with his 39th long ball on Sept. 22. He also showed versatility by manning both first base and the outfield.
Runner-up: Paul DeJong, STL (.285 BA, 25 HR)
50. Carlos Correa, 2015 AL (Astros)
Key stats: 22 HR, 22 2B, .857 OPS (135 OPS+)
Correa logged just 99 games for Houston, but made his presence felt by setting numerous franchise rookie marks while also becoming the first rookie shortstop on record to hit 10 homers within his first 45 career games.
Runner-up: Francisco Lindor, CLE (.313 BA, .835 OPS)
51. Bob Hamelin, 1994 AL (Royals)
Key stats: 24 HR, 65 RBI, .987 OPS (147 OPS+)
The 1994 strike kept Hamelin from posting even better numbers, but the designated hitter finished the year fifth the AL in slugging and OPS while averaging one homer for every 13 at-bats. Injuries would keep him from duplicating that kind of production again.
Runner-up: Manny Ramirez, CLE (17 HR, 60 RBI)
52. Stan Bahnsen, 1968 AL (Yankees)
Key stats: 2.05 ERA (140 ERA+), 17 wins, 10 CG
Bahnsen arrived late to Spring Training after an army commitment, and then proceeded to lead the Yankees' rotation in ERA. He shut out the reigning AL champion Red Sox at Fenway Park with 12 strikeouts on Aug. 1.
Runner-up: Del Unser, WAS (146 H, 66 R)
53. Jeff Bagwell, 1991 NL (Astros)
Key stats: 242 total bases, .294 BA, .824 OPS (139 OPS+)
The fruit of one of the most lopsided trades in history, Bagwell changed positions and showed a major power improvement from his time in the Minors while finishing fifth in the NL with a .387 OBP.
Runner-up: Orlando Merced, PIT (.275 BA, 83 R)
54. Jacob deGrom, 2014 NL (Mets)
Key stats: 2.69 ERA (128 ERA+), 9.2 K/9, 0.4 HR/9

Runner-up: Billy Hamilton, CIN (141 H, 56 SB)
55. Jose Canseco, 1986 AL (A's)
Key stats: 33 HR, 117 RBI, 15 SB

Runner-up: Wally Joyner, CAL (.290 BA, 100 RBI)
56. Michael Fulmer, 2016 AL (Tigers)
Key stats: 3.06 ERA (139 ERA+), 0.9 HR/9, 132 SO
Flashing a plus, mid-90s fastball, Fulmer struck out 11 Rays on May 21 and later compiled a 33 1/3 scoreless innings streak. He joined Jake Arrieta along the way as the second pitcher to pitch four straight scoreless outings of at least six innings while allowing three or fewer hits.
Runner-up: Gary Sánchez, NYY (20 HR, 42 RBI in 53 G)
57. Earl Williams, 1971 NL (Braves)
Key stats: 33 HR, 87 RBI, .491 SLG
Williams remarkably made his first professional appearance at catcher in mid-June -- and stayed behind the plate the rest of the season. He was more accomplished as a power hitter, homering into the upper decks at both Atlanta-Fulton County Stadium and Veterans Stadium.
Runner-up: Willie Montanez, PHI (30 HR, 99 RBI)
58. Gil McDougald, 1951 AL (Yankees)
Key stats: .306 BA, 41 extra-base hits, .884 OPS (142 OPS+)

Runner-up: Minnie Minoso, CLE/CWS (14 3B, 31 SB)
59. Jack Sanford, 1957 NL (Phillies)
Key stats: 19 wins, 188 SO, 3.08 ERA (124 ERA+)
The Phillies right-hander struck out 188 batters to lead the Majors, while also permitting an NL-best 7.4 hits per nine innings and completing 15 of his starts.

60. Eric Hinske, 2002 AL (Blue Jays)
Key stats: 24 HR, 38 2B, 272 total bases
