Getting more extreme

You wouldn't think the disparity between the Yankee starters and relievers could get even larger, but they have:

Starters: 21.2 innings, 9.97 ERA, .360 OBA (OUCH!)
Relievers: 23.1 innings, 1.16 ERA, .145 OBA

The Yankees would be doing much better if they could just limit their starting pitchers to 1 or 2 innings.
