The Boston Red Sox and Seattle Mariners could be ideal trade partners. One has plenty of young, top-tier pitching and the other has an excess of athletic position players, mostly lefties.
The Red Sox organization has picked up on their potential trade compatibility with the Mariners. Early in the offseason, Boston made them a shocking trade offer many fans didn't see coming.
Ryan Divish and Adam Jude of The Seattle Times reported that the Sox offered Triston Casas to the M's in exchange for one of their young starting pitchers, Bryce Miller or Bryan Woo. Seattle rejected the offer, and Casas remains a Red Sox, at least for now.
Potential trades between Boston and Seattle have been floated often since the two teams make so much sense as trade partners. The Mariners organization has previously expressed reluctance to trade from its rotation, and the denial of the Casas deal doubles down on that position.

Not only does Seattle wish to hold onto its elite rotation, Casas had a down year for the Sox in 2024. As his career stands now, he alone may not be an enticing enough offer to a team with quality pitching. The first baseman slashed .241/.337/.462 with a .799 OPS over 63 games last season. His injury-shortened campaign may have lowered his trade value in other teams' eyes —he's never played more than 132 games in the big leagues in his three-year career.
Despite the news that Boston missed out on a quality arm for the rotation, plenty of Sox fans are happy Casas remains in a Red Sox uniform. Boston's chief baseball officer Craig Breslow previously described Casas as "a guy that we think has 40-home run potential," and many Red Sox fans would like to see him get another chance to achieve his ceiling with the Sox.
It's still early in the offseason, though, and Casas has featured in plenty of proposed trade packages. This probably won't be the last time the Red Sox try and ship the 24-year-old elsewhere for pitching.
