We seem to have issues with getting players known to be great vs LHPs, but who just don't carry over that greatness once they are here. Maybe, it's the Fenway wall that messes them up. Maybe, it's the large RF that messes them up.
Cody Ross was the last one, I remember, doing well for us, but he actually was forced to play FT due to OF injuries.
Cody Ross:
career: .710 v RHPs/.906 v LHP
2012 w BOS: .729 v RHPs/ 1.010 v LHPs.
Jonny Gomes:
career: .712/.855
2013: .745/.795
2014: .510/.743
Chris Young:
career: .708/.823
2016: .766/.999
2017: .793/.590
I may be missing someone, but it looks like they almost always do better than the norn vs RHPs and are up & down vs LHPs.
Pearce:
career: .739/.858
2018 all: .785/1.049
w BOS: .762/1.299
