Yamamoto struck out eight but allowed four runs on seven hits with no walks across six innings during a no-decision against the Twins on Thursday.
Eight strikeouts set a new season high for Yamamoto, but the offense had to come through with three runs in the ninth inning to get him off the hook for his third straight loss. The right-hander owns an unsightly 9.64 ERA in his last three outings, and overall he is 4-2 with a 3.94 ERA, 1.04 WHIP, .169 batting average against and 49 strikeouts in 48 innings this season. Yamamoto will pitch next at the Mets on Tuesday.
