No it seems to be on all stats, player cards etc, i
think.
I thought it wasnt working right so i tested it out, started a test chise threw a fastball down the middle to the CPU to give him an easy hit, a left hander (Granderson) hits it, i press select and it shows batting average of .1000 against Right handed batters faced, when of course it should be left.
Its a minor stats bug, but its definately there, of course to get the correct readings just read them the other way round to see how your pitchers are doing against lefties and righties, i.e. if im Verlander and his stats say RHB .320 LHB .277 it actually means Righties are batting .277 against him and lefties .320, if you understand me.
Annoying but easy to live with.
