Athletics face Diamondbacks as managerial pressure mounts amid pitching struggles

The Oakland Athletics travel to Chase Field on Tuesday night for the second game of a three-game series against the Arizona Diamondbacks, a contest that underscores the stark contrast in fortunes between the two franchises. First pitch is scheduled for 9:40 p.m. ET, with the Diamondbacks listed as money line favourites in consensus odds. While Arizona sits half a game out of the final National League wild card spot, the Athletics are grappling with a 43-57 record and the worst run differential in Major League Baseball at minus-111.

Oakland’s managerial situation has drawn significant attention, with manager Mark Kotsay described as being on a major hot seat. Despite a 5-2 victory on Monday night, the Athletics have not won back-to-back games since late June. The team’s playoff probability has plummeted to 1.3 per cent, a sharp decline from a 30 per cent chance earlier in the season when they sat just half a game out of the division lead. The club’s struggles are compounded by a pitching staff that owns a 5.29 earned run average, ranking better than only the Colorado Rockies.

On the mound for Oakland is converted reliever Jack Perkins, making his seventh start of the season. Perkins enters the game having lost his past five outings, including a start where he allowed three runs over three innings in Detroit. The 26-year-old faces a familiar opponent, having been shelled by Arizona last year as a rookie. Projections suggest Perkins will face a tough challenge against an Arizona lineup that is expected to return star outfielder Corbin Carroll, who missed Monday’s game.

Arizona counters with the debut of rookie left-handed pitcher Kohl Drake, ranked as the franchise’s No. 10 overall prospect. Drake, a 6-foot-5, 220-pounder acquired in the 2025 trade deadline, posted a 6.92 ERA in 66.1 innings at Triple-A Reno this season. While the Diamondbacks are dealing with injuries to key starters Zac Gallen and Michael Soroka, who are on the injured list, and the potential loss of Corbin Burnes for the season, the team remains focused on the wild card race.

The Athletics’ offensive potential is anchored by young talent, including All-Star catcher Shea Langeliers and 2025 AL Rookie of the Year Nick Kurtz. However, the team’s inability to sustain wins and their poor run differential highlight systemic issues that extend beyond individual player performance. As the series continues, the pressure on Oakland’s leadership and pitching staff will likely intensify against a Diamondbacks side fighting to maintain its postseason positioning.
