HOUSTON (AP) — Justin Smoak homered to cap an eight-run burst in the seventh inning, leading Hisashi Iwakuma and the Seattle Mariners over the Houston Astros 9-8 Saturday.
Four straight walks started the Mariners' big burst as they overcame a 2-1 deficit.
Iwakuma (1-0) made his first appearance after starting the season on the disabled list because of a sprained middle finger.
Iwakuma allowed four runs and six hits in 6 2-3 innings. Fernando Rodney pitched the final 1 1-3 innings for his seventh save.
Dallas Keuchel (2-2) left after walking the bases loaded with no outs in the seventh.
