The Athletics designated veteran pitcher Aaron Civale for assignment on a busy day of moves that were announced on MLB.com’s transactions log on Wednesday ahead of their return from the All-Star break on Friday.
Right-handed reliever Yunior Tur was selected to the major league roster in Civale’s place, lining the organization’s No. 27 prospect, per MLB Pipeline, up for a potential big league debut this weekend when the Athletics host the Washington Nationals in West Sacramento, Calif.
According to an MLB.com report, the Athletics are also calling up No. 7 prospect Tommy White from Las Vegas to make his major league debut this weekend.
Civale, 31, signed as a free agent with the Athletics in February. His season started well with a 5-1 record and 2.70 ERA over his first nine starts. But he had an 8.25 ERA in three June starts and a 10.29 ERA through two July starts and has lost his last six starts.
He has a 48-51 record and 4.26 ERA with 723 strikeouts and 226 walks over 156 appearances (150 starts) for the Cleveland Guardians (2019-23), Tampa Bay Rays (2023-24), Milwaukee Brewers (2024-25), Chicago White Sox (2025), Chicago Cubs (2025) and Athletics.
Tur, 26, has a 1-0 record and 4.59 ERA over 27 appearances (five starts) spanning 51 innings for Las Vegas this season, striking out 64 and walking 26.
White, 23, was the 40th overall pick in the 2024 MLB Draft out of LSU. He has 24 home runs in 194 total minor league games, including 10 with a .303 batting average in 76 games this season between Double-A Midland and Triple-A.
The A’s are also calling up left-hander Brady Basso from Triple-A Las Vegas and utility player Donovan Walton, who they claimed off waivers from the Angels on Sunday.
As corresponding moves, they optioned catcher Brian Serven, first baseman Joey Meneses and right-hander Mason Barnett to Las Vegas.
