The risks are obvious, but if done right, free agency is the quickest way for a club to infuse its roster with proven talent and push itself to the next level.
Just look at the Dodgers, who have captured back-to-back World Series titles with major contributions from a slew of high-profile free agents.
Of the 28 players to appear in a game for the Dodgers in the 2025 postseason, 11 were acquired or retained via free agency. The club got a combined 25 WAR (per Baseball-Reference) from these 11 players during the regular season. That was only slightly behind the 26.2 WAR they got from their free-agent acquisitions during their 2024 championship season.
As the list below shows, only one World Series champion since the start of free agency in 1976 got more regular-season WAR from their free-agent signings the year they won it all than Los Angeles did in 2024. The 2025 Dodgers slot in at fourth on the list.
As this offseason gets underway, they’ll serve as a reminder for other teams of the upside free agency offers.
Note: The following criteria was used to determine the team WAR totals below:
1. 2009 Yankees
Total WAR from free-agent signings: 38
After their 13-year postseason appearance streak was snapped in 2008, the Yankees went on a free-agent spending spree that saw them land starters CC Sabathia and A.J. Burnett as well as first baseman Mark Teixeira. The Bronx Bombers also re-signed lefty Andy Pettitte. The moves paid immediate dividends, as New York christened the new Yankee Stadium with a championship in the park’s inaugural season. Sabathia, Burnett and Pettitte combined to start 69 games in the regular season and all 15 of New York’s games during the playoffs. Teixeira, meanwhile, produced 39 homers and 122 RBIs in the regular season and socked a walk-off dinger in Game 2 of the ALDS against the Twins.
The 2009 Yankees also got a huge postseason from Alex Rodriguez, who re-signed with the club after opting out of his previous contract in 2007. Johnny Damon (signed in 2006), Hideki Matsui (signed in 2002), Mariano Rivera (re-signed in 2007) and Jorge Posada (re-signed in 2007) were among the other notable players on this roster who were either added or retained in free agency.
2. 2024 Dodgers
Total WAR from free-agent signings: 26.2
Already one of the best teams in baseball, the Dodgers took it up a notch after their second straight NLDS defeat in 2023. Los Angeles put together one of the biggest free-agent hauls in baseball history, headlined by the additions of two-way superstar Shohei Ohtani (10 years, $700 million) and Japanese ace Yoshinobu Yamamoto (12 years, $325 million) for more than $1 billion combined. Los Angeles rounded out its free-agent signings with slugging outfielder Teoscar Hernández and utility man Kiké Hernández.
3. 2013 Red Sox
Total WAR from free-agent signings: 26
The Red Sox went through a significant overhaul after a disappointing 69-93 season under manager Bobby Valentine in 2012, though the first step actually came in August, when Boston sent Adrian Gonzalez, Josh Beckett, Carl Crawford and Nick Punto to the Dodgers in a stunning blockbuster trade that cleared a ton of money from its payroll.
4. 2025 Dodgers
Total WAR from free-agent signings: 25
The Dodgers secured their second straight title with a seven-game triumph over the Blue Jays in the World Series, becoming MLB’s first repeat champion since the Yankees won three straight from 1998-2000. From a roster perspective, the sequel looked a lot like the original. The signings of Shohei Ohtani and Yoshinobu Yamamoto after the 2023 season continued to pay major dividends, as did the earlier additions of Max Muncy in ’17 and Freddie Freeman in ’22.
The Dodgers stayed active in free agency following their 2024 championship victory, adding two-time Cy Young Award winner Blake Snell on a five-year, $182 million deal and re-signing Teoscar Hernández, Clayton Kershaw, Kiké Hernández and Blake Treinen. (They also landed Japanese phenom Roki Sasaki, though as an international amateur free agent, he doesn’t count for the purposes of this ranking.)
5. 2023 Rangers
Total WAR from free-agent signings: 23.3
While they lost deGrom to Tommy John surgery after six starts, Eovaldi filled in admirably as the Rangers’ ace in the regular season and finished 5-0 with a 2.95 ERA over six postseason starts. Seager combined with Semien to produce 14.3 WAR during the regular season and recorded 12 extra-base hits (six homers), 12 RBIs, 15 walks and a 1.133 OPS in the playoffs, culminating with an MVP-winning performance in the Fall Classic.
6. 2007 Red Sox
Total WAR from free-agent signings: 23.1
Arguably no free-agent signing in the 2006-07 offseason drew as much attention as Boston’s deal with pitcher Daisuke Matsuzaka, who came over from Japan amid considerable fanfare. The Red Sox also inked outfielder J.D. Drew , shortstop Julio Lugo and reliever Hideki Okajima. The results were mixed during the regular season, but all four had their moments in the playoffs. Meanwhile, a pair of free-agent moves made years prior continued to pay off, as David Ortiz (signed in 2003) and Manny Ramirez (signed in 2000) remained the focal point of Boston’s offense.
With their offseason trade for Josh Beckett and Mike Lowell also a factor, the Red Sox won the AL East, battled back from a three-games-to-one ALCS deficit against Cleveland and swept the Rockies in the Fall Classic to win it all.
7. 2004 Red Sox
Total WAR from free-agent signings: 22.5
What looked like a minor move at the time — signing designated hitter David Ortiz after he was non-tendered by the Twins following the 2002 season — ended up altering the course of baseball history.
Along with fellow free-agent additions Manny Ramirez (signed in 2000), Johnny Damon (signed in 2001) and Keith Foulke (signed in 2004), Ortiz helped the Red Sox end an 86-year title drought and finally break the Curse of the Bambino, overcoming a three-games-to-none ALCS deficit against the rival Yankees in the process. Ortiz ended up spending the rest of his career in Boston, winning three titles and putting together a resume that earned him a place in the Hall of Fame.
8. 2001 D-backs
Total WAR from free-agent signings: 21.8
With Johnson as their centerpiece, the D-backs became an instant contender and ultimately stunned the three-time defending champion Yankees in the 2001 World Series. The Big Unit won four straight NL Cy Young Awards from 1999-2002 and was named co-MVP of the 2001 Fall Classic alongside Schilling. With a championship in their fourth season, the D-backs became the fastest expansion team to win it all, eclipsing the Marlins at five seasons.
9. 1997 Marlins
Total WAR from free-agent signings: 20.2
Four of the 1997 Marlins’ top six players, in terms of WAR, were added in free agency, with Kevin Brown, Alex Fernandez, Moises Alou and Bobby Bonilla joining a nucleus that also featured Gary Sheffield, Charles Johnson, Jeff Conine and Liván Hernández. Alou led the 1997 team in homers and RBIs while finishing second in average and OPS. Bonilla was also among the Marlins’ top three hitters in RBIs, average and OPS. On the other side of the ball, Brown and Fernandez combined for 65 starts, 33 wins, 458 innings, 388 strikeouts and a 3.12 ERA.
The Marlins lost Fernandez to a torn rotator cuff after Game 2 of the NLCS against the Braves, but Brown helped the club upset Atlanta in the series, earning the win in Game 1 and the Game 6 clincher as the Marlins advanced to the World Series. Alou went deep three times, drove in nine runs and posted a 1.101 OPS in the club’s seven-game Fall Classic win over Cleveland.
10. 2019 Nationals
Total WAR from free-agent signings: 19.5
Washington also benefited from its decision to re-sign Howie Kendrick after acquiring him in a 2017 trade. Kendrick was integral to the Nats’ title run, as he hit a tiebreaking grand slam in the 10th inning of NLDS Game 5 against the Dodgers, won NLCS MVP honors after Washington’s sweep over the Cardinals and belted the decisive home run in Game 7 of the World Series against the Astros.
