The Red Sox landed the offseasons top rotation trade candidate this afternoon. Even after 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 Warming Bernabel Jersey market after the Crochet acquisition ( via Pete Abraham of the Boston Globe). The Globes Alex Speier reports ( ) that Boston is still engaged on 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 that the Sox are still having discu sions with the Mariners regarding their starting pitching. Adam Jude and Ryan Divish of the Seattle Times reported on Monday that Seattle in a framework that wouldve sent one of their young starters to the Sox for first baseman . President of baseball operations Jerry Dipoto has spoken repeatedly of the organizations reluctance to even consider moving , , or . could be a different story. The Mariners are reportedly 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, theres a belief within the industry that the righty is available ( ). There should be trade value, as Castillos deal aligns with what and have landed on three-year free agent deals. Yet Castillo isnt as appealing as the Ms young core of much more affordable starters. That price tag surely plays into the Ms willingne s to listen to offers, as theyre reportedly working with around $15-20MM in payroll room and could use multiple hitters. Its unlikely that the Mariners would trade Castillo strictly for prospects. Theyd presumably need an MLB hitter to anchor the return. Casas might be too big an ask if theyre not sending one of their younger arms to Boston. Outfielder is another potential Red Sox trade candidate, though the Ms have le s need for an outfielder than they do for an impact bat in the corner infield like Casas. Whether anything will come of the Soxs pursuits remains to be seen. At the very least, its clear Breslow and his front office arent fully satisfied with a rotation comprising Crochet, , , and . They gave up a good package of young talent to get Crochet, but hes 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. Seth Halvorsen Jersey
