| 8/26/25 | A's Calling Up Former Kansas City Royals Prospect For MLB Debut. Following the diagnosis of a Grade 1 flexor strain for Jacob Lopez on Monday, the A's officially placed the left-hander on the IL on Tuesday. Taking his place on the roster will be former Kansas City Royals prospect Mason Barnett, whom the Athletics acquired at the 2024 MLB Trade Deadline as part of the return for Lucas Erceg. Barnett is ranked as the A's No. 11 prospect by MLB.com. Barnett had not been on the A's 40-man roster before the move, but to make room for Zack Gelof on the roster yesterday, they decided to designate Luis Urías for assignment, which left them with 39 players on the 40-man roster, essentially clearing up a spot for Barnett.

| 8/20/25 | A's Jacob Lopez Has Scoreless Streak Stopped in Win Over Minnesota Twins. A's left-hander Jacob Lopez is slowly but surely making his name known around baseball following yet another impressive start. This time he was facing a depleted post-deadline Minnesota Twins roster, but that shouldn't take away from the run that he's been on since July 26, a span of five starts. In his last five outings, Lopez has now tossed 30 innings, given up a total of 18 hits, two earned runs, five walks, and has struck out 36. The A's as a team went into Tuesday's game in Minnesota with a cumulative 3.36 ERA since the date that Lopez's streak began, which has led them to a 13-8 record.
