Astros option Mike Burrows after rough start, recall Alimber Santa

The Houston Astros made a quick adjustment to their starting pitching plan on Tuesday, optioning right-hander Mike Burrows to Triple-A Sugar Land and recalling rookie right-hander Alimber Santa. The move comes after Burrows struggled in Monday’s 12-11 loss to the Nationals, when he allowed 10 runs (seven earned) in 4 1/3 innings. For a team that has been looking for stable production from its rotation, the decision indicates that the club is trying to find answers at the top of the pitching staff sooner rather than later.

Burrows’ most recent outing was not an isolated problem this season. Through 18 games and 17 starts, he has posted a 5.99 ERA across 94 2/3 innings, numbers that are among the worst for Houston’s rotation starters. also reported that Burrows has allowed 21 home runs, which ranks among the highest totals in baseball, and that batters are hitting.292 against him, again near the top of qualified starters in terms of unfavorable results.

The Astros’ offseason investment in Burrows makes the move more consequential. reported that Houston acquired him in December as part of a three-team trade with the Rays and Pirates, with the intent of adding rotation depth. According to that same report, the trade also sent Houston away with prospects Jacob Melton and Anderson Brito, underscoring why the club is actively monitoring how quickly Burrows can settle into consistent MLB form.

In Santa, Houston is choosing a different profile for the next look. noted that Santa pitched to a 0.71 ERA in eight earlier appearances with the big league club this season, and highlighted that he threw two perfect innings in his MLB debut, closing out a combined no-hitter against the Rangers on May 26. The recall gives the Astros a live option to evaluate whether Santa’s early-season effectiveness can provide more immediate relief at the major-league level.

The timing of the transaction also intersects with the Astros’ longer-term pitching health picture. reported that right-handers Ronel Blanco (Tommy John surgery) and Lance McCullers Jr. (right rotator cuff impingement) are scheduled to continue rehab assignments for Sugar Land on Tuesday night. It also noted that Cristian Javier was activated from the injured list last week, keeping the door open for additional rotation flexibility if needed.

What to watch next is whether Houston turns this into more than a one-for-one correction. Burrows’ option to Triple-A gives him a chance to work on command and run prevention away from major-league hitters, while Santa’s recall is an immediate test of whether the early results can translate into sustained performance. The next round of rotation decisions will likely clarify what the Astros believe they are working with in the current pitching mix, and how quickly the club can align its major-league needs with its rehabbing arms. If Burrows remains in a prolonged adjustment period, the Astros may also lean further on their depth to stabilize innings in the second half.

For now, the roster move sets a clear message: the Astros are not waiting for a fresh start to correct recurring problems. With Burrows’s struggles documented in both his recent outing and season-long numbers, and with Santa already shown at least brief effectiveness at the top level, Tuesday’s shuffle becomes a practical bet on change rather than continuity. The rotation will reveal whether that change produces more stable starts, or whether Houston’s search for consistency needs another pivot soon.
