Greinke allowed two runs on a hit and a walk in 1.1 innings during Tuesday's win over the Red Sox in Game 4 of the ALCS. He didn't factor into the decision.
Greinke had gone a month between starts since he's worked out of the bullpen to begin the postseason, and he wasn't able to provide much length Tuesday. He threw just 18 of his 37 pitches for strikes, and his free passes helped to contribute to a two-run first inning for the Red Sox. Across the right-hander's first two appearances of the postseason, he's recorded a 7.71 ERA and 2.57 WHIP in 2.1 innings. He'll presumably be available out of the bullpen later in the ALCS.
