The Houston Astros went 0-2 to start the season and ended the week leading the majors in runs scored. Week one was a lot.

Lance McCullers Jr. took the mound Monday against Boston and delivered seven innings, one run, and nine strikeouts — his longest outing since September 2022. The crowd gave him a standing ovation. It was earned.

Also this week: Tatsuya Imai makes his MLB debut at Daikin Park with four walks in three innings, the Astros score 11 unanswered runs in a single comeback win, Isaac Paredes keeps making the front office regret trying to trade him, and all four minor league affiliates open within 48 hours of each other.

Prospect Spotlight: Miguel Olla, the $75,000 signing from the Dominican Republic who carried a no-hitter into the sixth inning in his 2026 debut.
