In Scherzer's 12 career playoff starts:
Through the sixth inning: 2.81 ERA, 0.97 WHIP, .178 BAA
After the sixth inning: 18.00 ERA, 2.75 WHIP, .429 BAA
I imagine he knows this stat better than anyone. And wants to prepare himself to go deeper into games so he is more effective in the postseason. I imagine he knows more about how to do this than anyone else. And certainly more than anyone here. It was a relatively meaningless game. If your 2 time CY Young Ace tells you that he wants to stay in and pitch 120 pitches in a game after you've clinched to better prepare himself for the playoffs you do it, every time, without question.
The fact that this is being questioned is beyond absurd.
