With active rosters expanding from 26 to 28 today, the Red Sox are calling up right-hander Zack Kelly and catcher Ali Sánchez, per Tim Healey of The Boston Globe. The latter had signed a minor league deal with the Mets just over a week ago but the Red Sox traded for him last night, per Healey. The Mets received cash in the deal, per Christopher Smith of MassLive. The Sox opened a 40-man spot for Sánchez by moving infielder Marcelo Mayer to the 60-day injured list, per Jen McCaffrey of The Athletic.
At first blush, it might be a bit confusing that the Sox and Mets swung a trade after the deadline. However, as MLBTR explained last month, certain trades are still allowed. A player on a minor league contract which has not been selected to the majors can be traded. That’s true even if the player was in the majors earlier in the season via a different contract. Last year, for instance, Cavan Biggio played for the Dodgers. After being designated for assignment and released, he signed a minor league deal with the Giants. After the deadline, he was traded from the Giants to Atlanta.
The situation is basically the same with Sánchez, who has played for the Blue Jays and Red Sox in 2025. The Sox designated him for assignment a couple of weeks back. He cleared outright waivers, elected free agency and signed with the Mets. Since this Mets deal hadn’t been selected to the majors, he was eligible to be traded back to Boston. By being acquired last night, prior to September, he’s eligible to be on Boston’s postseason roster.
Sánchez will give the Sox a three-catcher setup for the final month of the season, joining Carlos Narváez and Connor Wong. Sánchez still has a fairly limited major league track record. He has appeared in four big league seasons but with just 47 total games played. In those contests, he has a .185/.222/.235 slash line.
However, he’s generally regarded as a strong fielder and his offensive numbers have been better in a larger sample of minor league playing time. From 2022 to the present, he has stepped to the plate 943 times at the Triple-A level with a .272/.348/.418 line. That translates to a 96 wRC+, which is 4% below league average but decent for a catcher, especially a backup catcher.
Wong is slashing just .189/.253/.231 on the season, so perhaps there’s a scenario where Sánchez plays himself into the #2 slot behind Narváez and cracks the postseason roster. For now, he’ll give the club a bit more cover for a potential injury while also giving the skipper a bit more freedom for in-game roster moves. Sánchez is out of options but has just over a year of service time and can therefore be retained beyond this season if he’s holding a roster spot at season’s end.
