Season 22 is exactly what I would expect from him.
Since Rp's throw so few innings (small sample size every season) the stats can vary widely with just a couple of bad outings. Take away the following preformances, 4/3 PM2, 4/4 PM, 4/16 AM and 4/29 AM and he looks quite a bit better in his other 44 games even with a couple bad games left in.
