One name that hasn't been mentioned enough this offseason and a potential game-changing rotation arm is Marcus Stroman. Sure, he is not coming off a season like Jordan Montgomery (more on him shortly), Blake Snell, or Gray had, but he is just one of those guys that puts up consistent results year in and year out that could be a major boost to Boston's rotation.
It was somewhat surprising to see Stroman opt out of his deal with the Cubs and leave $21 million on the table, but he is clearly betting that the current market for starting pitching is going to play in his favor. For the vast majority of his career, Stroman has been a lock to post a 3ish ERA, miss an okay amount of bats, and get a TON of soft groundballs. While a pitcher who has the ball put in play against him a decent amount isn't completely ideal given the state of the Red Sox's infield defense, it should certainly help that the quality of contact against Stroman is usual very poor.
Given that Stroman left a guaranteed $21 million in Chicago, he is probably going to be looking for at least a three or four year deal especially considering that it is likely that his is going to be his last chance at a big pay day at 32 years old. However, it wouldn't be the first time that Craig Breslow was in a front office that targeted him as Breslow was a key voice on the Cubs' pitching decisions when Stroman signed with Chicago back in 2021.
