At the plate, Houston has relied heavily on José Altuve and Jeremy Peña with Yordan Álvarez sidelined. Altuve sits at .263 with 26 home runs and 74 RBI, while Peña has posted a .305 average and .364 OBP to balance the lineup. Christian Walker’s 82 RBI lead in run production. Even with some key names out, Houston’s success at home has been effective.

Mariners vs Astros Pick

Prediction: With Woo and Brown on the mound, runs will be at a premium. Both pitchers are capable of working deep and keeping the ball in the yard, and Houston’s slight edge in lineup depth, plus home field, gives them a narrow advantage. Astros 3, Mariners 2.
