His first two years he had a .923 and .959 OPS vs. LHP with 11 HR in 193 PA and 10 HR in 185 PA, respectively . This year he's at .716 and hasn't hit a HR yet and has hit 20 vs. RHP, which ties him with D. Lee for the season high.
Any explanations? Did they figure out how to pitch him from that side? Is this the part of his game that gets hot as the year goes on?
