The platoon split for Alcides is a concern, yes, but let's keep it in perspective-- even Hardy's career line is .258/.312/.404 vRHP, and Hart's is .263/.305/.464. He's a little beyond what you'd normally expect for a platoon split, but we shouldn't expect him to be hitting .300 against righties. And as TLB mentioned, that's one reason to keep him at AAA for a while yet. And in terms of BABIP, I did a long story at BCB a while back and eventually concluded that because of a bunch of factors we can expect a .330-.340ish BABIP for him (in the minors, anyway) due to his good rates of contact, rare popouts, frequent bunt hits, and speed.
