Seattle Mariners vs Houston Astros Prediction
I’m not excited to get behind Miller, who will make his season debut after dealing with an oblique injury. However, the Astros’ pitching remains god awful and that includes McCullers, who has a 7.41 ERA and 1.50 WHIP through 34 innings. In 19.2 frames at home, McCullers has a 7.32 ERA and .257 allowed batting average. McCullers has allowed 3 or more earned runs in each of his last 6 starts. Miller can’t be worse than that. Give me the M’s on the road.
