Yamamoto did not factor into the decision in Monday's 9-0 win against Atlanta, allowing four hits and two walks with three strikeouts over four scoreless innings.
Yamamoto generated a solid 10 whiffs on 72 pitches but also threw just 42 strikes. Despite the shaky control, the 26-year-old was able to increase his workload from 59 pitches Tuesday and has not allowed an earned run over eight innings in his two outings since returning from the injured list. On the season, he owns a 2.63 ERA, 1.07 WHIP and 95:19 K:BB across 82 innings and lines up for a favorable home matchup with the Rockies this weekend.
