Porcello has been f***ed raw by this defense over and over, 4 starts loss because of them. About 60+% of ball in play to left are not converted when he pitch, up from 25% last season. There were 2 last night that were routine plays.
The only thing he has done differently is using the fastball too much up. He has a great K/BB.
A good defense infield can shave over half a run off his ERA, which he should sit in the mid 3, an excellent #2 behind Sale.
