The Astros are officially adding right-hander Ethan Pecko to the active roster, according to MLB Trade Rumors, giving Houston fresh pitching depth right when it needs it most. This isn't some throwaway September call-up either — Pecko has been the subject of real internal discussion in Houston's front office for over a week.

It's easy to see why the Astros are leaning on him now. Ronel Blanco, a guy Houston was counting on to help stabilize the rotation after returning from Tommy John surgery, got optioned back to Triple-A Sugar Land on August 16 after posting a brutal 7.71 ERA over his first 5 games back. He allowed 5 runs in 4 relief innings during a 10-5 loss to Seattle that made the decision easy. Add in the fact that Houston didn't add a starter at the trade deadline, and suddenly a rotation with real holes needed a real answer.
Enter Pecko. A 6th-round pick out of the 2023 draft, he was named the organization's minor-league pitcher of the year in 2024 and has spent this season grinding through 15 starts at Triple-A Sugar Land, putting up a 4.94 ERA across 74⅔ innings. Not eye-popping numbers, but respectable enough that GM Dana Brown was openly floating him as an option, telling reporters there was an "outside chance" Pecko could debut against the Angels — and that "we're having discussions right now." Pecko was even scratched from his own Triple-A start over the weekend just to stay available.
That's a fast track for a guy who wasn't a marquee prospect on draft day. Sixth-rounders don't usually get fast-tracked into a big-league rotation battle in year 3, but injuries and underperformance up top have a way of accelerating timelines. Pecko's readiness — not flash, just being the arm who's actually built up and stretched out right now — is what got him the call.
For the Astros, this is as much about survival as opportunity. Houston's rotation was supposed to lean on veterans and TJS returnees; instead it's leaning on a prospect who was pitching in Sugar Land two weeks ago. Whether Pecko sticks depends entirely on how he handles major-league bats in his first look — but for a team scrambling for length in the back half of August, he's the arm they've got.
Watch for Pecko to get thrown right into the fire, likely as a spot starter before Houston decides whether he's a rotation piece down the stretch or a stopgap while Blanco and Hayden Wesneski try to find their form again in the minors.
