Minute Maid Park — Houston, Texas
Takeaway: Seattle sends its ace, Luis Castillo, to the mound looking to take the series and climb back to .500, while Houston turns to Spencer Burrows, a young left-hander trying to stabilize a rotation that has been battered all season. The Astros’ 16–27 start is their worst in over a decade, and they desperately need pitching consistency. Seattle, meanwhile, has relied heavily on its rotation to stay afloat while the offense continues to search for rhythm. With Castillo on the mound and Houston’s lineup still dangerous at home, this matchup has the feel of a tense, low-scoring battle early with potential late-inning volatility.
