It was his first and his third start where he gave up 8 ER a piece. Most of the rest were good/decent, but he had a few stinkers late. 3 of his last 4 starts were "meh" or worse.
And to BorntoRun's point, he had 15 scoreless interleague innings against the AL, 7 against us and 8 against Minnesota and a 6 inning 4 ER effort against the Chisox.
