6:40 p.m.: The White Sox have announced the trade, also saying they will send a player to be named later or cash to the Red Sox as part of a swap.
6:11 p.m.: The White Sox are trading catcher Reese McGuire to the Red Sox, per Jesse Rogers ESPN. Robert Murray of FanSided reports that veteran left-handed reliever Jake Diekman is headed to Chicago in a deal.
McGuire, 27, gives Boston an immediate option to pick up the playing time left by tonight’s Christian Vazquez trade to the Astros. While McGuire hasn’t been able to put together much of a consistent streak in the big leagues, he’s a former top prospect with three more seasons of club control remaining beyond the current year. He’s hitting .225/.261/.285 on the season but has the best defensive output on the year: +7 Defensive Runs Saved, a 31% steal rate and positive pitch-framing scores from both FanGraphs and Statcast.
McGuire is out of minor league options, so the acquisition suggests the Red Sox plan to carry him on the big league roster for the foreseeable future. With Vazquez now in Houston and Kevin Plawecki set to become a free agent following his season, McGuire gives the Sox a defensive-minded option as a backup for at least next year. Prospects Ronaldo Hernandez and Connor Wong give the Sox some in-house options in 2023 (and possibly up the ranks this year), but the front office could look at ways to improve behind the dish during the offseason (or when possible). with more transactions in the next 22 hours).
The 35-year-old Diekman, meanwhile, has been rumored to provide an option for Chicago’s veteran left-hander in the front office. He’s having a somewhat typical season by his standards, missing a lot of at-bats but walking too many hitters. He currently has a 4.23 ERA with a 29.8% strikeout rate but the worst walk rate of any reliever in the majors (17.5%) for Diekman’s command has always been an issue.
Despite the flood of free passes, Diekman added a hard-throwing, swing-and-miss southpaw to the late-innings mix for manager Tony La Russa. He is playing on a two-year, $8MM contract that runs through the 2022-23 season and carries a $4MM club option for the 2024 campaign. As such, the Chisox could consider Dykman for at least one more season and possibly between two late-innings options, depending on his value over the next 14 months.
The White Sox have been without lefty Aaron Baumer for most of the summer thanks to a strained lefty, and youngster Garrett Crochet underwent Tommy John surgery earlier in the season. That led general manager Rick Hahn and his staff to target some more lefty help in the bullpen. 30-year-old rookie Tanner Banks was previously La Russa’s only southpaw option out of the ‘pen. Triple-A lefties Anderson Severino and Bennett Sousa are both on the 40-man roster, but each has been hit hard in limited MLB work this season.
