An impressive collection of talent has hit the open market, and players are now eligible to sign with any team. Here is a division-by-division breakdown of the key free agents for all 30 Major League clubs.
NATIONAL LEAGUE EAST
Key free agents: RHP Brad Brach, 1B Lucas Duda, 3B Ryan Flaherty, OF Nick Markakis, C Rene Rivera, RHP Anibal Sanchez, RHP Peter Moylan
Markakis was a valuable member of a youthful Braves club in 2018, providing veteran leadership and making the All-Star team for the first time in his career. Atlanta has a stellar farm system that is loaded with pitching prospects, which is one of the reasons why Sanchez is unlikely to be back after his impressive rebound campaign. But without an obvious replacement for Markakis in right field, the door remains open for the soon-to-be 35-year-old to return. Suzuki formed a productive catching tandem with Tyler Flowers across 2017-18, but the 35-year-old signed a two-year deal with the Nationals.
Key free agents: INF/OF Derek Dietrich
The Marlins' roster is replete with players who are at the early stages of their big league careers, putting them years away from free agency. After trading multiple big-name players last offseason, Miami will likely now look to deal veterans Starlin Castro and Martin Prado, as they are owed nearly $27 million combined in 2019. Meanwhile, Dietrich elected free agency after being designated for assignment and clearing waivers.
New York Mets
Key free agents: LHP Jerry Blevins, INF Wilmer Flores, OF Austin Jackson, C Devin Mesoraco, RHP AJ Ramos, INF Jose Reyes
With Travis d'Arnaud, T.J. Rivera and Juan Lagares returning from injuries, the Mets have obvious replacements for Mesoraco, Reyes and Jackson next year. Blevins is more likely to be back than Ramos, whose recovery from right shoulder surgery is expected to extend into next June and possibly longer. The club also chose to non-tender Flores, its longtime utility player.
Key free agents: 3B/OF Jose Bautista, INF Asdrubal Cabrera, LHP Aaron Loup, C Wilson Ramos, 1B Justin Bour, LHP Luis Avilan
All four players on Philadelphia's list were acquired late in the 2018 campaign as the Phillies made a playoff push that ultimately fell short. Instead of bringing back Ramos, who is sure to fetch a sizable multi-year deal, the Phils may give 25-year-old Jorge Alfaro another chance to show he can handle starting duties behind the plate. Cabrera could be a fallback option if the Phillies are unable to land Manny Machado in free agency.
Key free agents: OF Bryce Harper, RHP Jeremy Hellickson, RHP Kelvin Herrera, RHP Greg Holland, 1B Mark Reynolds, C Matt Wieters, LHP Tim Collins, RHP Joaquin Benoit
Harper is one of the top free agents on the market, and the Nats will likely make a major push to keep him in Washington. The club might also be interested in bringing back Holland and Hellickson, but the two righties are sure to draw interest from other clubs after boosting their value with the Nats. Washington is expected to try to upgrade at the catcher spot, which could leave Wieters looking for a new home. Left-hander Sean Doolittle will be back, as the Nats exercised his option for 2019.
Key free agents: LHP Jorge De La Rosa, 2B Daniel Murphy, LHP Justin Wilson, LHP Jaime Garcia, C Bobby Wilson, INF Ronald Torreyes
The Cubs exercised their $20 million club option for Hamels, who was acquired from the Rangers at the non-waiver Trade Deadline and recorded a terrific 2.36 ERA over 12 starts. Chicago could try to retain Murphy (particularly given Addison Russell's suspension), as president of baseball operations Theo Epstein spoke highly of the second baseman's contributions after his acquisition from the Nationals. Jesse Chavez won't be back, however, as the right-hander signed a two-year deal with the Rangers, returning to the club that traded him to Chicago last July.
Key free agents: RHP Matt Harvey, CF Billy Hamilton
Cincinnati elected to keep Harvey at the non-waiver Trade Deadline instead of flipping him to a contender, and now face a decision about the right-hander, given that he has expressed openness to returning and the Reds will be seeking starting pitching depth this offseason. Outside of Harvey, the Reds don't have any key departures or options to worry about this winter, though Scooter Gennett is due for free agency following the 2019 season.
Key free agents: LHP Xavier Cedeno, LHP Dan Jennings, LHP Gio Gonzalez, OF Curtis Granderson, RHP Jordan Lyles, LHP Wade Miley, 3B Mike Moustakas, RHP Joakim Soria
The Brewers have most of their pitching depth locked up beyond this season, with Gonzalez, an in-season acquisition, and Miley, who was initially signed to a Minor League contract before the season, the only two starters set for free agency this offseason. Moustakas and Soria became free agents when they turned down mutual options for $15 million and $10 million, respectively. The club picked up Jeremy Jeffress' $3.175 million team option, but turned down Lyles' option for $3.5 million.
Key free agents: INF/OF Josh Harrison, SS Jordy Mercer
After making a splash by trading for Chris Archer in 2018, the Pirates appear to be mostly set with their pitching staff but will be looking for a bat in the offseason, likely at shortstop. Even if they don't make a Manny Machado-sized splash at that position, the market is deep this offseason, with Jose Iglesias, Freddy Galvis and Adeiny Hechavarria among the names in play. The Pirates opened up some payroll flexibility and a roster spot by declining Harrison's $10.5 million option.
St. Louis Cardinals
Key free agents: 1B Matt Adams, RHP Bud Norris
Adam Wainwright agreed to a one-year deal Monday to return for his 15th season with the Cardinals. Improving the bullpen to build around Jordan Hicks will be a priority for St. Louis, especially with the departure of Norris, who provided stability at closer for much of the season. Though Adams likely won't be on the Cardinals' radar again, St. Louis is thought to be looking for an impact left-handed hitter, with needs at outfield and third base.
Key free agents: RHP Clay Buchholz, RHP Randall Delgado, 2B Daniel Descalso, LHP Jake Diekman, OF Jon Jay, OF A.J. Pollock, C Chris Stewart, RHP Shelby Miller, RHP Brad Boxberger
The D-backs could lose two key contributors this winter, as Corbin agreed to a six-year deal with the Nationals and Pollock likely will exceed Arizona's price range. Buchholz and Descalso are candidates to return, though. The D-backs unsurprisingly picked up Paul Goldschmidt's $14.5 million club option for '19, while making one-year, $17.9 million qualifying offers to Corbin and Pollock, which they both rejected.
Key free agents: C Drew Butera, OF Carlos Gonzalez, OF Matt Holliday, 2B DJ LeMahieu, RHP Adam Ottavino, OF Gerardo Parra
The Rockies will have to decide whether they want to compete for LeMahieu this winter or if they're ready to turn the reins at second base over to one of their middle-infield prospects, Garrett Hampson and Brendan Rodgers. They also face decisions in the outfield and in the bullpen, with a number of key players entering free agency. That includes Parra, whose $12 million option was declined.
Los Angeles Dodgers
Key free agents: RHP John Axford, 2B Brian Dozier, C Yasmani Grandal, RHP Daniel Hudson, SS Manny Machado, RHP Ryan Madson
Machado is among the headliners in this year's star-studded free agent class, and it's unclear if the Dodgers will try to retain the star infielder, whom they acquired from the Orioles at the non-waiver Trade Deadline. Clayton Kershaw, who had an opt-out clause that would have voided the final two years of his deal, signed a three-year, $93 million contract to stay in L.A. Meanwhile, Los Angeles made qualifying offers to Grandal and the oft-injured Ryu, and the latter accepted.
San Diego Padres
Key free agents: C A.J. Ellis, SS Freddy Galvis
The Padres' 2018 roster will remain mostly intact with only Galvis and Ellis entering free agency, and both are candidates to return. Ellis is less likely to be re-signed, however, with young catchers Austin Hedges and Francisco Mejia in the mix. San Diego may also let Galvis walk if he wants a multi-year deal, with Fernando Tatis Jr. (San Diego's No. 1 prospect, per MLB Pipeline) nearing big league readiness and Luis Urias (San Diego's No. 4 prospect) likely to take over as the club's starting second baseman in 2019.
San Francisco Giants
Key free agents: OF Gregor Blanco, LHP Derek Holland, C Nick Hundley, OF Hunter Pence, RHP Hunter Strickland, OF Gorkys Hernandez
San Francisco exercised its options on Madison Bumgarner and Pablo Sandoval, bringing them back for 2019. The Giants may try bring back Holland, who enjoyed a bounceback campaign and anchored an injury-riddled Giants rotation in 2018, and Hundley, who capably backed up Buster Posey, but they will likely part ways with veterans Pence and Blanco.
AMERICAN LEAGUE EAST
Key free agents: OF Adam Jones, SS Tim Beckham, C Caleb Joseph
The O's list has just one man on it, as they traded nearly every player on an expiring contract, including Manny Machado, Zach Britton and Brad Brach, during their 2018 roster purge. Baltimore would have dealt Jones as well, but he was unwilling to waive his 10-and-5 rights. Jones may be interested in returning, but he would likely need to accept a significantly reduced role as the Orioles look to the future.
Boston Red Sox
Key free agents: RHP Joe Kelly, RHP Craig Kimbrel, 2B Ian Kinsler, 2B Brandon Phillips, LHP Drew Pomeranz
Even with David Price confirming he won't be opting out of the four years and $127 million remaining on his contract, the Red Sox still have a number of important players hitting free agency. Kimbrel is the biggest name among them, and he unsurprisingly rejected the qualifying offer he received from Boston. After bringing back Steve Pearce on a one-year deal, the Red Sox also reunited with Nathan Eovaldi on a four-year contract following his excellent stint with Boston in the second half and the postseason. Chris Sale will be back after Boston unsurprisingly picked up his $15 million club option for 2019, and Eduardo Nunez is also returning to the defending World Series champions by exercising his $5 million player option.
New York Yankees
Key free agents: LHP Zach Britton, LHP J.A. Happ, SS Adeiny Hechavarria, RHP Lance Lynn, OF Andrew McCutchen, RHP David Robertson, 2B/OF Neil Walker
The Yankees have a busy offseason ahead of them, especially on the pitching side of the ledger. Even if prospect Justus Sheffield is ready to claim a rotation spot behind Luis Severino, Masahiro Tanaka and the re-signed CC Sabathia that still leaves at least one open starting job. Meanwhile, the Yankees' vaunted bullpen could lose two key pieces in Robertson and Britton. The club declined a $12.5 million club option for 35-year-old outfielder Brett Gardner, New York's longest-tenured player, but the Yankees re-signed him to a one-year deal reportedly worth $7.5 million after the veteran posted a .690 OPS this past season.
Tampa Bay Rays
Key free agents: OF Carlos Gomez, RHP Sergio Romo
Romo was an integral member of the Rays' pitching staff for much of the 2018 season, racking up 25 saves and making five appearances as an "opener." However, he recorded a 10.00 ERA in September and will be 36 years old on Opening Day in '19. The cost-conscious Rays may opt to move on and give an opportunity to a younger alternative. As for Gomez, the veteran outfielder is unlikely to be back after posting a .634 OPS over 118 games in 2018.
Toronto Blue Jays
Key free agents: RHP Tyler Clippard, RHP Marco Estrada, INF Yangervis Solarte
Much like Baltimore, Toronto dealt many impending free agents during the 2018 season, including Josh Donaldson, J.A. Happ, Steve Pearce, Curtis Granderson and John Axford. The Jays picked up Justin Smoak's reasonable $8 million club option, but they could look to trade the veteran this offseason, with Rowdy Tellez seemingly ready for an expanded role at first base. Estrada is likely gone after recording a 5.27 ERA with a 4.97 FIP in 61 starts over the past two years, as the Blue Jays can likely get similar production from a younger and cheaper pitcher.
Chicago White Sox
Key free agents: 1B/DH Matt Davidson, OF Avisail Garcia, RHP Jeanmar Gomez, RHP Miguel Gonzalez, LHP Hector Santiago, RHP James Shields
The White Sox are close to emerging from their rebuild, and the club could look for more pitching help this offseason, since Michael Kopech is now sidelined for 2019 after undergoing Tommy John surgery. Chicago picked up Nate Jones' $4.65 million option, but declined Shields' option for $16 million, opting instead for a $2 million buyout, and decided not to tender contracts to Davidson or Garcia.
Key free agents: RHP Cody Allen, OF Michael Brantley, OF Melky Cabrera, OF Rajai Davis, OF Brandon Guyer, LHP Andrew Miller, LHP Oliver Perez, INF Adam Rosales, RHP Josh Tomlin
Miller headlines a productive crop of prospective free agents departing Cleveland this season, with outfield and the bullpen being the two areas that stand to be hit hardest by the departures. The Indians do have some security in the bullpen with midseason acquisitions Brad Hand and Adam Cimber both controllable for several more seasons, but bolstering the relief corps will be an offseason priority for the Tribe, who got subpar seasons from both Allen and Miller in 2018. Outfield is also an area of need, especially with Lonnie Chisenhall signing with the Pirates and even more so if Brantley departs. The Tribe picked up Carlos Carrasco's $9.75 million club option for '19 but opted to buy out Guyer for $250,000 instead of exercising his $3 million option. Third baseman Josh Donaldson's stay in Cleveland was brief, as he inked a one-year, $23 million deal with the Braves.
Key free agents: SS Jose Iglesias, LHP Francisco Liriano, C James McCann, C Jarrod Saltalamacchia
Iglesias, Liriano and the retiring Victor Martinez are the key departures for the rebuilding Tigers. They likely will be in the market for a shortstop, as they don't have an immediate heir lined up in the event of Iglesias' departure, and will likely look to add to the rotation.
Kansas City Royals
Key free agents: SS Alcides Escobar, RHP Jason Hammel
After trading Jon Jay, Lucas Duda, Kelvin Herrera and Mike Moustakas this season, the Royals figure to let Escobar walk, as Adalberto Mondesi is now their starting shortstop. The Royals will pay a $2 million buyout to get Hammel off the books instead of exercising his $12 million mutual option for 2019, but they'll bring back Wily Peralta, who emerged as their closer last season, on arestructured contract.
Key free agents: RHP Matt Belisle, 2B Logan Forsythe, C Chris Gimenez, 1B/DH Joe Mauer, 1B/DH Logan Morrison, RHP Ervin Santana, OF Robbie Grossman
The most pressing offseason question for the Twins will be at first base, with the possible departure of Mauer to either free agency or retirement and Morrison's disappointing performance in 2018, after which the Twins declined to pick up his $8 million option for '19. The departures of Forsythe, Brian Dozier (traded to Dodgers) and Eduardo Escobar (traded to D-backs) also leave openings in the middle infield for the Twins. The Twins need lots of help in the bullpen and could always use more starting depth, with Santana's $14 million option also being declined.
Los Angeles Angels
Key free agents: RHP Jim Johnson, RHP Junichi Tazawa, OF Chris Young, OF Eric Young Jr., RHP Blake Wood, RHP Blake Parker, RHP Matt Shoemaker
The Angels will retain much of their core. Johnson will likely draw interest on the open market for clubs in need of dependable bullpen arms. Young suffered a season-ending injury (labral tears in both hips) but is expected to be ready for Spring Training.
Key free agents: DH Evan Gattis, UTIL Marwin Gonzalez, LHP Dallas Keuchel, C Martin Maldonado, RHP Charlie Morton, LHP Tony Sipp
Keuchel figures to be one of the most sought-after starting pitchers on the market this winter. The 2015 AL Cy Young Award winner has spent his entire career with the Astros, but could anchor another team's staff in 2019. Morton also figures to draw considerable interest coming off his first All-Star season at age 34. Brian McCann returned to Atlanta on a one-year deal, but Maldonado remains part of a deep class of veteran backstops.
Key free agents: LHP Brett Anderson, RHP Trevor Cahill, RHP Jeurys Familia, RHP Mike Fiers, RHP Kendall Graveman, RHP Edwin Jackson, OF Matt Joyce, 2B Jed Lowrie, C Jonathan Lucroy, RHP Shawn Kelley
The A's looming free agents are headlined by a pair of veterans in Lucroy and Lowrie. Lucroy is more likely to return with Franklin Barreto ready to take over as Oakland's everyday second baseman. Joyce is likely the odd man out in a crowded A's outfield. It's unclear if the A's will try to retain any of their veteran starting pitchers.
Key free agents: 2B Gordon Beckham, DH Nelson Cruz, LHP Zach Duke, OF Cameron Maybin, RHP David Phelps, UTL Andrew Romine, OF Denard Span, RHP Adam Warren
Cruz represents the biggest free agent choice for the Mariners this winter. Both sides have expressed interest in a reunion, but Seattle must decide whether it wants to commit to a multi-year deal with the 38-year-old slugger or utilize that money elsewhere, with needs on the pitching staff and in center field. Span's $12 million mutual option was declined by Seattle, making the outfielder a free agent.
Key free agents: 3B Adrian Beltre, RHP Bartolo Colon, RHP Doug Fister, RHP Yovani Gallardo, LHP Martin Perez, Tony Barnette, RHP Matt Bush
The Rangers are awaiting Beltre's decision on his baseball future, and if the third baseman opts to continue playing, they could re-sign him. Texas declined its options on Fister, Moore and Perez, making them free agents. Colon and Gallardo aren't expected to return.
