Harper is games started by a lefty .255/.344/.464
Harper in games started by a righty .248/.322/..384
It doesn't appear as if he has troubles with left handed starters, just the LOOGY types. Probably a good stat for LaRoche use to get a contract extension.
Blue - is that stat against only the starter or against all pitchers who pitch in that game? You wonder if the reason those stats start to look like each other is because lefties are more likely to get replaced by a righty (at least in a mid inning switch) while righties may be more frequently replaced by LOOGYs specifically fro the Harper match up.
