I'd commented recently about Porcello at that 90 pitch level. Interesting stats -
Porcello ERA for innings 1-3:
4.06, 4-6:
4.73, 7-9:
7.84!
In comparison, for Max it's 4.47, 3.35, 1.84. He had some early games where he couldn't get untracked early on.
For Verlander, numbers are 3.20, 2.64, 2.33.
Opponent BA each time through the order:
Porcello: .276, .296, .360, .500
Max's #'s: .240, .240, .278, .200
For JV it's: .205, .254, .194, .194
Overall, Porcello has averaged about 93 pitches per outing.

Stretching him long just doesn't pay off.
