At 10:10pm ET, my AL West GOW is on Seattle. Give me Luis Castillo and the Mariners over Hunter Brown and the Astros in the opening game of this important series. Castillo is already 2-0 with an exemplary 0.71 ERA in July. Castillo also has a 2.98 ERA and 1.04 WHIP at home. Brown is 0-2 with an ERA of 7.88 in 4 appearances versus the Mariners in his career. He also has a 5.70 ERA and 1.64 WHIP on the road with a .304 opponent's batting average. Play on Seattle
