DiFelice did not have bat splits in AAA because there are no LH bats with big pop in the minors, except for the rare Gamel type who has not been called up yet. When Brad Nelson and such are the big power bats to avoid, you'll have success, but that does not translate to the bigs. As I said, his splits versus major league LH hitters is atrocious, and he'd be lucky to make it through a lefty laden lineup as a SP. When you have the numbers right there, and still think maybe he'd have success, the only argument is that stats are meaningless. He's correctly placed as a righty specialist.
