The Athletics designated him for assignment on May 16, 2025.

Houston Astros (2025–Present)

The Houston Astros claimed Alexander off waivers on May 18, 2025, providing him with a fresh opportunity. Inserted into the Astros’ depleted starting rotation due to injuries, he responded with his best major league performances. On August 4, 2025, at LoanDepot Park against the Miami Marlins, Alexander hurled six scoreless innings to lead an 8–2 victory, recording the longest scoreless outing of his career to that point.

Alexander followed that effort with another standout performance on August 10 at Yankee Stadium, where he tossed six shutout innings against the New York Yankees. He carried a no-hit bid into the sixth inning before the Yankees broke through. For the 2025 season with Houston, Alexander appeared in 14 games with 13 starts, posting a 4–2 record and 3.66 ERA. Following the season, he was optioned to the Triple-A Sugar Land Space Cowboys to begin the 2026 campaign.
