Astros To Promote Colton Gordon

The Astros will recall left-hander Colton Gordon from Triple-A Sugar Land to start tomorrow’s game, reports Chron.com’s Leah Vann. Gordon, who’ll be making his MLB debut, will step into the rotation spot of the injured Hayden Wesneski. He’s already on the 40-man roster, so Houston will only need to make a corresponding 26-man roster move to bring him to the majors.

Gordon, 26, has gotten out to a terrific start in 2025. He’s taken the mound eight times and logged 42 1/3 innings of 2.55 ERA ball, fanning 25.3% of his opponents against a 4.7% walk rate. Both those marks are better than average — considerably so, in the case of that walk rate — as is his 43.5% ground-ball rate.

The Astros’ 2021 eighth-rounder out of the University of Central Florida, Gordon entered the 2025 season ranked 20th among Astros prospects at Baseball America and 14th at MLB.com. He doesn’t throw hard, sitting just 91.1 mph on his four-seamer, but the 6’4″ southpaw benefits from above-average command and a deep, six-pitch arsenal that helps keep hitters off balance. In addition to that four-seamer, Gordon also throws a sinker, slider, changeup, curveball and cutter.

With Wesneski (elbow inflammation) joining Spencer Arrighetti (broken thumb), J.P. France (2024 shoulder surgery), Cristian Javier (2024 Tommy John surgery) and Luis Garcia (2023 Tommy John surgery, and multiple setbacks) on the injured list, Houston’s pitching depth is being put to the test. Gordon and righties AJ Blubaugh and Miguel Ullola are the top internal options in Triple-A, while righties Ryan Gusto and Shawn Dubin are both on the big league roster and capable of starting. Dubin, however, just made his season debut after a lengthy IL stint due to shoulder inflammation and is not stretched out. He’s pitched only in one-inning stints so far and appears set for a second straight year working primarily out of the bullpen, so perhaps his days as a rotation option are behind him.

The ’Stros boast a formidable one-two rotation punch in Hunter Brown and Framber Valdez, but the rest of the group is on shakier standing. Lance McCullers Jr. just returned from an injury absence of more than two years, so it’s tough to know what to expect from him. Ronel Blanco was a godsend for the 2024 Astros but never seemed likely to replicate last year’s 2.80 ERA, which was propped up by a tiny .220 average on balls in play and bloated 83.6% strand rate. He’s worked to a 4.04 ERA in 2025, which is more in line with last year’s 4.17 SIERA and 4.15 FIP. To Blanco’s credit, he turned in one of the best starts by any pitcher in MLB this season last time out, blanking the Reds over eight innings of two-hit ball with 11 strikeouts, but he entered that start with a 4.98 ERA, a 21.9% strikeout rate and 11% walk rate.

Given the injuries up and down the staff, Gordon ought to get several chances to prove himself in 2025. He was only selected to the 40-man roster this past November, so he’s in the first of three minor league option years. He can be controlled through at least the 2031 season.
