Arrieta seemed to damage his stock early on—his ERA stood at 5.44 in mid-May—but a final three months in which he had a 2.26 ERA and didn't allow more than three runs in any of his 13 starts pushed him back near the top of this list. He could be the rebuilding Phillies' version of Jon Lester: a long term cornerstone for a club for whom contention might not be far off.
