Red Sox chief baseball officer Craig Breslow met with the Boston beat on Monday to discu s the teams offseason. MLBTR has Breslows notes on and , respectively. and were among those to cover Breslows other comments. Most notably, the CBO pushed back against trade rumors swirling around first baseman . Im not totally sure where it comes from. Were not shopping Triston , Breslow said. We see him as a guy that can hit in the middle of the lineup for a really long time here in Boston. Ive seen some of the speculation about what deals may or may not have existed, or what may or may not have been proposed, and there was nothing that was remotely close. Were certainly not shopping him. Reporting has generally characterized the Sox as being open to a Casas trade without suggesting theyre actively trying to deal him. That has been most prevalent in the context of attempting to line up a deal with Seattle for a controllable starter. reported during the Winter Meetings that the Mariners Jovel Smith Jersey had rebuffed interest from the Sox in swapping Casas for a young starter like or . Boston has seemingly not had interest in a Casas for framework. wrote last week that the Sox wouldve wanted Seattle to take on the underwater contract in that situation. In any case, it looks increasingly likely that Casas will remain on the Red Sox going into next season. Boston has added and to a rotation that already included , and . Giolito is shooting for an Opening Day return from internal brace surgery. That gives the Sox at least six viable starters, while and are on hand as depth options. is likely to kick back to the bullpen once he returns from his own elbow surgery.

Theres a decent amount of upside, but its not surprising that Breslow indicated theyll look for another addition. The free agent relief market has barely moved. Only three relievers , and have signed multi-year deals. Holmes is stretching out as a starter after signing a three-year contract with the Mets. Chapman and (who accepted a qualifying offer from Cincinnati) are the only other relievers to sign for a guarantee above $10MM. The slowly-developing relief market in part reflects a weaker than average free agent group. However, the top two relievers, and , remain unsigned going into the new year. , , and are other relievers who have yet to sign. is the top name on the trade market, though the Cardinals seem to prefer to hold him until the deadline. In contrast to the bullpen, Boston has yet to make a move for a right-handed hitter aside from a trade for backup catcher . The Sox lost from a group that was already very left-handed. Breslow reiterated that the Sox wanted impact production from a right-handed bat out of the middle of the lineup . He left open the po sibility of internal improvements but noted theyre certainly also engaged in conversations for players that arent yet in the organization .
