J.A. Happ was offered arbitration, and will return in 2012.
This makes sense, given how cheap he is. Before you get all crazy, let's look at Happ's June/July:
1-9 record. 51.2IP, 71H/44ER, 46K:29BB, 8 homers allowed, .332/.408/.565, .389 BABIP, 7.66 ERA/1.94 WHIP.
Then Aug/Sept:
3-4 record. 41IP, 29H/16ER, 36K:23BB, 4 homers allowed, .201/.310/.333, .238 BABIP, 3.51 ERA/1.27 WHIP.
