Three starters—Cristian Javier (15-day IL, right shoulder strain), Jake Meyers (10-day IL, right oblique), and rookie Tatsuya Imai (tired arm)—have been lost to injuries during the road trip, forcing Mike Burrows to the mound against Mariners right-hander George Kirby (1-2, 3.60 ERA). Jeremy Peña remains sidelined with right knee tightness, thinning the Astros lineup further, while Mariners enjoy home-field advantage and J.P. Crawford's return from the IL bolstering their infield. Both teams hover around 6-10 in the AL West standings, highlighting a tight divisional matchup.
