The Red Sox are known to be looking for starting pitching, with chief baseball officer Craig Breslow having said that he wants to “raise the ceiling” in the rotation. They have been connected to marquee free agents like Corbin Burnes and Max Fried as well as notable trade candidates like Garrett Crochet, Bryce Miller and Bryan Woo. Peter Abraham of The Boston Globe reports that Walker Buehler is another free agent they have interest in.
Whether Buehler would count as raising the ceiling would be a matter of debate at this point, as it’s been a few years since he was at his best over a meaningful stretch of time. From 2018 to 2021, he tossed 564 innings for the Dodgers, allowing 2.82 earned runs per nine. He combined a 27.7% strikeout rate with a 6.1% walk rate and 44.7% ground ball rate. He also posted good results in 15 postseason starts for the Dodgers in that time.
But in 2022, he had an ERA of 4.02 before requiring Tommy John surgery, the second of his career. He missed the entire 2023 campaign and didn’t immediately bounce back this year. He only made 16 starts in 2024 and had rough results, most prominently a 5.38 ERA. His 18.6% strikeout rate was below league average and also far from his previous form.
He did finish things on a positive note, in a very small sample but on a very big stage. After getting lit up by the Padres in the NLDS, he went on to throw ten shutout innings over his final three appearances of the Dodgers’ World Series run. That included four shutty against the Mets in the NLCS, a five-inning start against the Yankees in the third game of the World Series, followed by the final three outs in game five.
Going into 2025, Buehler is an interesting risk/reward play. His previous upside is tantalizing but he’s been hurt or middling for the past few years. He did have that strong finish in the playoffs but most modern front offices won’t be swayed by such a small sample, even it was under the brightest lights in baseball.
That uncertainty means that Buehler could likely be had for a relatively low price, which could either turn into a bargain or a waste. The Dodgers declined to issue Buehler a $21.05MM qualifying offer at season’s end, evidently not valuing him worth that price point. At the start of the winter, MLBTR predicted Buehler for a one-year deal with a $15MM, though the market for pitching has been stronger than expected, with mid-rotation or back-end guys like Luis Severino, Yusei Kikuchi, Frankie Montas, Matthew Boyd and Clay Holmes outearning their projections so far.
Despite the recent results, Buehler has proven to be quite popular this winter, having already drawn the interest of Atlanta, the A’s, Yankees, Mets, Cubs, Tigers and now Red Sox. For Boston, they tried a buy-low move last year which hasn’t worked out so far. After a few rough years, they gave Lucas Giolito a fairly modest $38.5MM guarantee on a two-year deal but elbow surgery wiped out his 2024 season.
The injury is not really the fault of the Boston front office but Giolito was a risky choice even before that and it was generally expected they would target more surefire rotation upgrades this time around. The club’s decision makers have talked about being aggressive this winter and putting together a club capable of winning the division, even if that means paying the competitive balance tax.
RosterResource pegs the club’s CBT number at $181MM right now, about $60MM shy of the $241MM base threshold. That means they have plenty of room to go after top free agents like Burnes and Fried, but they are also at least considering a more modest strike for someone like Buehler, or perhaps a combination of the two.
The rotation currently projects to include Tanner Houck, Kutter Crawford and Brayan Bello, with openings at the back. Giolito will be expected back at some point, though likely not at the start of the season. Guys like Richard Fitts, Cooper Criswell and Quinn Priester are on the roster but fairly unestablished and still optionable. Alongside Buehler, the Sox could consider other mid-rotation or back-end free agents such as Sean Manaea, Nathan Eovaldi, Jeff Hoffman, Nick Pivetta, Andrew Heaney, Jose Quintana, Max Scherzer, Justin Verlander and others.
