Red Sox Remain In Rotation Market Following Crochet Deal

The Red Sox landed the offseason’s top rotation trade candidate this afternoon. Even after acquiring Garrett Crochet from the White Sox for a four-prospect package, Boston is on the hunt for starting pitching.

Chief baseball officer Craig Breslow told reporters that the Sox remained in the rotation market after the Crochet acquisition (Bluesky link via Pete Abraham of the Boston Globe). The Globe’s Alex Speier reports (on X) that Boston is still engaged on Corbin Burnes as well as mid-tier rotation targets.

That could evidently take the form of either a free agent move or a trade. Jon Morosi of the MLB Network tweets that the Sox are still having discussions with the Mariners regarding their starting pitching. Adam Jude and Ryan Divish of the Seattle Times reported on Monday that Seattle rebuffed interest in a framework that would’ve sent one of their young starters to the Sox for first baseman Triston Casas. President of baseball operations Jerry Dipoto has spoken repeatedly of the organization’s reluctance to even consider moving George Kirby, Logan Gilbert, Bryan Woo or Bryce Miller.

Luis Castillo could be a different story. The Mariners are reportedly open to discussing Castillo, whom they owe $68.25MM over the next three seasons. The deal also has a vesting option for 2028. According to Mark Feinsand and Daniel Kramer of MLB.com, there’s a belief within the industry that the righty is available (X link). There should be trade value, as Castillo’s deal aligns with what Luis Severino and Nathan Eovaldi have landed on three-year free agent deals. Yet Castillo isn’t as appealing as the M’s young core of much more affordable starters. That price tag surely plays into the M’s willingness to listen to offers, as they’re reportedly working with around $15-20MM in payroll room and could use multiple hitters.

It’s unlikely that the Mariners would trade Castillo strictly for prospects. They’d presumably need an MLB hitter to anchor the return. Casas might be too big an ask if they’re not sending one of their younger arms to Boston. Outfielder Wilyer Abreu is another potential Red Sox trade candidate, though the M’s have less need for an outfielder than they do for an impact bat in the corner infield like Casas.

Whether anything will come of the Sox’s pursuits remains to be seen. At the very least, it’s clear Breslow and his front office aren’t fully satisfied with a rotation comprising Crochet, Tanner Houck, Brayan Bello, Kutter Crawford and Lucas Giolito. They gave up a good package of young talent to get Crochet, but he’s eminently affordable from a financial perspective. Boston should have the flexibility to continue identifying free agent targets or take on a notable salary in trade.
