Corky BowmanThis guy is in my one world (Summer of 49), let's disregard that vsL. versus righties though he is a little similar to your guy, except the power and contact are transposed
here are his slash numbers vs righties in Hiram Bithorn (0,+2,0,+2,+3)
.317 /.421 /.748
quite impressive, although i think given low splits (below 30) i'd rather have great power and average contact than great contact and average power
my guess for a slash line would be .280/.360/.320
