Assuming X-man continues to perform as well as he did yesterday, or basically at that level, I say start him at third over Burroughs. Let Burroughs be the "super utility man" (except, he'd be indirectly resting Giles and Ryno by playing third and putting X in the OF for those games)
My one major concern with X though, is that if he does great this year (which i'm hoping he does, obviously) I cringe at our shot of getting him back next year, considering his agent is Scott Bora$$
