White Sox's Miguel Castro: Shifted to 60-day injured list
Rotowire
The White Sox transferred Castro (knee) from the 15-day injured list to the 60-day IL on Wednesday.
The move frees up a spot on the 40-man roster for right-hander Ryan Cusick, whom the White Sox claimed off waivers from the Tigers. Castro will miss the rest of the season after undergoing surgery Tuesday to repair a torn patellar tendon in his right knee.

White Sox's Miguel Castro: Moves to injured list
Rotowire
The White Sox placed Castro on the 15-day injured list Friday due to a torn patellar tendon in his right knee.
Castro suffered the injury during Wednesday's game against the Mets and is set to miss the rest of the season, and it's unclear if he'll be ready for the start of the 2026 campaign. The right-hander will likely be shifted to the 60-day IL once Chicago needs an opening on the 40-man roster.

Miguel Castro: Released by Arizona
Rotowire
The Diamondbacks released Castro on Wednesday.

The veteran reliever missed significant time with a shoulder injury this season and when healthy posted a 5.93 ERA and 8:3 K:BB over 13.2 innings. However, Castro's solid track record should earn him another look somewhere, likely on a minor-league contract.

Diamondbacks' Miguel Castro: Allows eighth-inning run
Rotowire
Castro allowed one run on two hits over one-third of an inning in Friday's 6-5 extra-inning loss to Atlanta.
Castro, who entered with one out in the eighth inning and a string of righties due up, gave up a pair of doubles that started Atlanta's comeback from a 5-2 deficit. Kevin Ginkel could not hold the lead in the ninth, as the Diamondbacks didn't execute well -- pitching or fielding -- at the end of the game. The right-handed Castro is part of the setup crew and will get high-leverage appearances.

Diamondbacks' Miguel Castro: Blows lead, takes loss
Rotowire
Castro (5-4) was tagged with Thursday's loss to Atlanta. He allowed three runs on two hits and one walk over two-thirds of an inning.
Castro, who began the eighth inning protecting a 5-3 lead, sandwiched a pair of outs around a double before getting into trouble. He walked Ozzie Albies before Austin Riley took him deep for a three-run home run. Although Castro's 3.4 BB/9 is an improvement over previous seasons, it's still a high number and the right-hander walked a delicate line before Thursday's costly free pass. A one-time part of the closer picture, Castro has since returned to a middle-relief role, one in which he's had recent success. Castro entered the game with a 1.50 ERA over his previous 12 innings.
