When you look at his statcast page, he's never been above 60th percentile for xERA, xBA, xSLG, xISO, K%. He's a fine pitcher who gives you a lot of innings without walking batters. If the Sox were going to put a really good IF defense out there, it'd make sense for them to lock him up. He's a better version of Derek Lowe IMO. Lowe was a pretty good pitcher until his late 30's. If Montgomery avoids injury, he could be decent. He's become a better pitcher as he's thrown his sinker more (up to 42% last year, was in the 20's in 20-21 and 30's in 22).
