Notes

Cody Bolton gets the start for Houston as the Astros look to avoid a sweep in Seattle. With the rotation depleted by injuries, Bolton steps into a larger role against a Mariners lineup that has shown signs of life this series. Houston’s offense remains capable of putting up runs, but the challenge continues to be limiting damage on the mound.
