If you cherry pick it to try to include games after the All-Star break in the first half, then there is a dramatic difference. But that's rather misleading. His best stretch of the year was the three games he had after the All-Star break, coming off 8 days of rest. That was the only time all year he had 3 quality starts in a row. Like I said, he had very poor peripherals all year. In the first half he had a 9.81 H/9, 4.25 BB/9 and a 1.56 WHIP. It's not like he was a good starter until he got tired later in the year. He greatly overperformed the entire season and if he pitched down to the level of his peripherals he probably wouldn't have kept his spot in the rotation.
