Napoli with runner on first, less than 2 out: 111 PA, .843 OPS, 33 RBI, 13 GIDP
Pedroia with runner on first, less than 2 out: 141 PA, .865 OPS, 25 RBI, 18 GIDP
Napoli hasn't been horrible in that situation. I would guess the GIDP rate is about average for a RH hitter with power. The strikeouts would certainly reduce the number of productive outs he has.
