He's the best defensive outfielder that we have after Victorino. He's the perfect late inning defensive replacement. Once Ortiz comes back, either Nava or Carp lose all of their ABs. Until yesterday, I would have bet on Carp getting sent out, but Carp looks like he can do some damage to RH pitching. His natural position is first base so he can spell Napoli as well as play some LF in Fenway.
