The White Sox have outrighted right-hander Tayron Guerrero and left-hander Kodi Medeiros to Triple-A, the team announced (hat tip to The Athletic’s James Fegan). Guerrero and Medeiros each cleared waivers after being designated for assignment since the start of the new year.
Guerrero was claimed off waivers from the Marlins in early December following a season that saw the righty post a 6.26 ERA over 46 innings out of Miami’s bullpen. The hard-throwing Guerrero has yet to harness his 99mph fastball into a consistent force at the MLB level, as while he has a 9.4 K/9 over his 106 career big league innings, he has also issued a lot of free passes — a 7.0 BB/9 last season, boosting his overall career BB/9 to 5.7.
Control has been a persistent issue for Guerrero throughout his decade-long professional career, as he also has a 5.8 BB/9 (with a 4.02 ERA and 9.0 K/9) over 346 2/3 minor league innings. Guerrero just celebrated his 29th birthday two days ago, so while he’d count as a late bloomer, there’s still time for him to become a useful relief weapon if the White Sox can get him on track.
Selected 12th overall by the Brewers in the 2014 draft, Medeiros has yet to reach even the Triple-A level through six seasons in pro ball. Medeiros has a 4.77 ERA, 8.6 K/9, and 1.82 K/BB rate through 545 minor league frames (starting 91 of 139 games). The southpaw came to the White Sox in July 2018, as part of the trade package in the deal that sent Joakim Soria to Milwaukee.
Medeiros’ first full year in Chicago’s farm system was far from a success, as he had a 5.10 ERA over 83 innings for Double-A Birmingham. However, Medeiros saw much more work as a reliever than in the past, starting only nine of 28 games, and he fared much better out of the bullpen — a 2.55 ERA over 42 1/3 relief innings, as opposed to a 7.75 ERA over 40 2/3 frames as a starter. This could hint at a new direction for Medeiros, who is still just 23 years old.
