I honestly didn't think of Verlander's Series shortcomings until I came across it in a comments section for the Series. What makes it a trifle puzzling is that his numbers in both the ALDS (8-1 W-L, 3.08 ERA in 13 starts) and the ALCS (7-4 W-L, 3.01 ERA in 12 starts) are stellar.
After Dave McNally's first start against the Dodgers in Game 1 of the 1966 Series, his ERA stood at 7.71. He didn't last three innings, walking five and giving up two earned runs (the last runs the Dodgers would score in the entire Series). Needless to say, he did a little better after that.
Some other Orioles notables:
Mike Flanagan had a 3.32 Series ERA (in 19 IP), but it ballooned to 5.51 in three ALCS starts (one with Toronto).
Scott McGregor was the true postseason stud for the Orioles. In four Series starts, he was just 2-2, but posted a 2.12 ERA in 34 innings. He was just as good in the ALCS, going 1-1 with an 0.57 ERA in two starts.
That's good stuff.
I forgot McGregor being such a clutch pitcher.
