The Cincinnati Reds have announced that left-handed pitcher Brandon Williamson has been moved to the 15-day injured list, citing fatigue in his left shoulder. This decision follows a period of significant recovery for Williamson, who sat out the entire 2025 season after undergoing Tommy John surgery. In a corresponding roster adjustment, the team has brought up right-handed reliever Zach Maxwell from their Triple-A affiliate, the Louisville Bats.
Williamson's recent performance on the mound saw him exit Wednesday night's game after just three innings, where he conceded four runs on four hits, along with four walks and four strikeouts, in a substantial home defeat to the Colorado Rockies. The following morning, he underwent an MRI scan to assess the extent of his shoulder issue. Fortunately, the structural integrity of his shoulder was confirmed to be sound, providing a measure of relief for the team and the player.
Manager Terry Francona confirmed the positive MRI results, stating that Dr. Tim Kremchek examined Williamson and administered a cortisone injection into his shoulder. Williamson is now set to embark on a structured rehabilitation program, focusing on regaining his range of motion and building strength in the affected area. This recovery plan is crucial for his return to the pitching rotation.
Throughout the current season, Williamson has accumulated a 2-3 record, an earned run average of 6.11, and has recorded 19 strikeouts. Notably, he has also issued 20 walks across 28 innings over six starts, leading the National League in this category. His career statistics reflect a record of 7-8 with a 4.69 ERA, 64 walks, and 129 strikeouts over 159.1 innings, spanning 33 appearances (32 starts) for the Reds from 2022 to 2024, and again in 2026.
Williamson's recent injury history includes a five-month stint on the injured list in 2024 due to a left shoulder strain. Shortly after his return from that injury, he sustained a torn ulnar collateral ligament in his left elbow, which necessitated Tommy John surgery and led to him missing the entirety of the 2025 campaign. The latest setback underscores a challenging period for the pitcher.
Zach Maxwell, who is now joining the Reds' active roster, is recognized as the 17th-ranked prospect within the organization by MLB Pipeline. The 25-year-old reliever made his rookie debut in 2025, pitching 10 innings with a 4.50 ERA, four walks, and 13 strikeouts over eight relief outings. This season, the imposing 6-foot-6, 275-pound Maxwell has posted a 1-0 record with a 5.91 ERA in 12 appearances for Louisville. Maxwell was drafted by Cincinnati in the sixth round of the 2022 MLB Draft out of Georgia Tech.
In summary, the Cincinnati Reds have placed left-handed pitcher Brandon Williamson on the 15-day injured list due to a fatigued left shoulder. This move highlights the persistent injury struggles for Williamson, who is now initiating a targeted rehabilitation regimen. In response, the team has called up promising right-handed reliever Zach Maxwell to reinforce their bullpen.
