He is a definite 3rd hole hitter against RHP, and I wouldn't hesitate to bat him lead off against LHP. If you have a better leadoff option, then he could hit 2nd, 6th, 8th or 9th (in that order).
He's hitting only .229 vs lefties, but he has a .362 OBP so he's been fine for in the lead off spot vs lefties. Doing very well in teh #3 spot vs righties too. :)
