The Chicago White Sox agreed to terms with relief pitcher Dan Altavilla on a one-year, $1 million contract ahead of Friday's series opener at Baltimore.

The White Sox made room on the 26-man roster by placing fellow right-hander Miguel Castro on the 15-day injured list with a torn patellar tendon in his right knee.

Altavilla, 32, was released by the White Sox on May 24 after going 1-1 with a 2.49 ERA in 20 bullpen appearances at Triple-A Charlotte this season.

Altavilla is 8-8 with a 4.36 ERA and one save in 124 career games (one start) for the Seattle Mariners (2016-20), San Diego Padres (2020-21) and Kansas City Royals (2024).

Castro, 30, sustained the season-ending knee injury during the ninth inning of Wednesday's 9-4 road victory against the New York Mets.

Castro has no decisions and a 7.50 ERA in six relief appearances this year. He is 22-28 with a 4.24 ERA and 14 saves in 425 games (four starts) over 11 seasons with seven teams.
