Astros Place Hunter Brown on IL With Right-Shoulder Discomfort

For the first time in five major league seasons, Hunter Brown landed on the injured list.

The Houston Astros placed the 27-year-old right-hander on the 15-day IL on April 5 with right-shoulder discomfort, making the move retroactive to April 2. The announcement came before Houston's 12-10 walk-off loss to the Oakland Athletics in Sacramento, a sobering backdrop for a team that had entered the day at 6-3 and alone atop the AL West.

Brown first noticed the issue during his between-starts throwing program Friday at Sutter Health Park in Sacramento. He underwent an initial MRI exam there before flying to Houston to be evaluated by the Astros' team doctors, with a full timetable for return dependent on additional diagnostic testing. Manager Joe Espada, speaking to reporters before Sunday's game, offered measured reassurance while acknowledging the uncertainty ahead. "He didn't sound concerned, which is good," Espada said. "But also it's new, right, so we're going to let the doctors evaluate him and then we'll see where we go from there." Espada added: "Hopefully, this doesn't keep him out for a long time."

The timing lands with particular weight given how Brown had performed. His final start before the IL came April 1 against the Boston Red Sox: six innings, one run, one hit, eight strikeouts, two walks, and a win. Through two starts in 2026, he carried a 1-0 record, a 0.84 ERA, a 1.03 WHIP, and 17 strikeouts across 10⅔ innings, building on what was already a career-defining 2025 season.

That 2025 campaign established Brown as a genuine frontline arm: a 12-9 record, 2.43 ERA, 1.03 WHIP, and a career-best 206 strikeouts over 31 starts and 185.1 innings, producing a 6.1 WAR that led the Astros staff. It earned him his first AL All-Star selection and a third-place finish in Cy Young voting behind Detroit Tigers ace Tarik Skubal and Boston Red Sox left-hander Garrett Crochet. He had entered Sunday fourth on Caesars' AL Cy Young odds board for 2026 before the announcement reset those projections.

In his place, Houston recalled right-hander Christian Roa from Triple-A Sugar Land. Roa, 27, carries a career 4.52 ERA over 171⅔ minor league innings as a swing man, with more favorable numbers in limited major league time with the Miami Marlins. Houston's remaining rotation, built around Mike Burrows, Cristian Javier, Tatsuya Imai, and Lance McCullers Jr., will carry the load in the near term. At Sugar Land, Jason Alexander was on regular rest as of Sunday and represented the most immediate candidate for a Monday start against the Colorado Rockies, while Spencer Arrighetti, who pitched Friday, would need additional days before being available.

This marks Brown's first IL stint in a professional career that dates to the Astros selecting him in the fifth round of the 2019 MLB Draft out of Wayne State University in Detroit. He made his MLB debut on September 5, 2022, and has since compiled a 3.44 career ERA over 94 starts. The Astros dealt with a rash of rotation injuries throughout 2025, and how quickly Brown's shoulder responds to rest and treatment will shape the tone of their 2026 campaign well before summer begins.
