How long are you going to hold on to that tired theory? I know it matches your views on TLR but just look at this ballclub.
Before today's game:
Carp 2: BA .278 obviously much better after today.
Kamatsu: .286
Shane Robinson: .556
Only Carp2 has a few more PA this year. Some players just can't for whatever reason put it together at the MLB level. He has plenty of chances everything else is just excuses. Rasmus tried the same one and it isn't working any better for him. I think he just has a mental issue he needs to overcome or he will be a AAAA player until he does.
