SEATTLE -- The Athletics' rotation took a hit Saturday when the club placed right-handed starter J.T. Ginn on the 15-day injured list, citing an elbow impingement in his throwing arm. The move, announced just before the team's series in Seattle, comes after Ginn had his most recent start pushed back due to fatigue and lingering soreness in his elbow.

In a corresponding transaction, the A's recalled right-hander Jack Perkins from Triple-A Las Vegas. Perkins, who has appeared in limited big-league action this season, is expected to provide depth out of the bullpen or possibly step into a spot-start role.

Ginn, 27, last pitched on August 26, a start in which he labored through five innings. The team initially cited fatigue when they delayed his next turn in the rotation, but further evaluation revealed the impingement, leading to the IL placement. The timeline for his return remains unclear, though the 15-day designation suggests the club hopes he will be back before the season ends.

Despite the injury, Ginn's 2024 campaign has been a rare bright spot for the struggling Athletics. He entered the season with modest expectations but quickly established himself as the most reliable arm in the starting staff. Over 24 starts and 138 1/3 innings, he has posted a 3.71 ERA while striking out 121 batters and walking 57. His 9-8 record, while not spectacular, reflects the limited run support he has often received.

Twice this season, Ginn came within striking distance of a no-hitter. The most memorable of those bids came in May against the Los Angeles Angels, when he carried a no-hit bid into the ninth inning before surrendering a hit. That performance, along with his consistent command and improved secondary pitches, cemented his status as a potential building block for the A's future.

His absence now leaves a gap in a rotation that has already been plagued by inconsistency. The A's, who are in the midst of a rebuilding phase, have relied heavily on young arms. Ginn's injury is a setback not only for the team's immediate depth but also for his personal development, as he was on pace to set career highs in nearly every category.

Perkins, 26, has made a handful of appearances for the A's this season, posting a 4.50 ERA in 12 innings out of the bullpen. He will likely be used in long relief or as a spot starter while Ginn recovers. The A's have not announced who will take Ginn's next scheduled turn in the rotation.

As the season winds down, the focus for the Athletics will be on getting Ginn healthy and back on the mound. The elbow impingement, while not considered a major structural injury, requires careful management to avoid further complications. The club's medical staff will monitor his progress closely, with an eye on preparing him for a full offseason program.

For now, the A's will have to find a way to fill the void left by their most consistent starter. The performance of Perkins and other call-ups in the coming weeks will be critical as the team evaluates its pitching depth heading into the winter.
