For all the naysayers in this thread: Please check out De Aza's stats at Charlotte.
Last night he went 5 for 6 with a couple of doubles.
He's hitting .476 with a .532 OBP, over his last 10 games.
On the season he's now hitting .320 with a .403 OBP.
He's 9 for 9 in stolen bases, and already has 3 more extra base hits than Pierre, in just 122 at bats, which is less than half as many at bats as our pathetic current lead off hitter.
De Aza has also driven in 3 more runs than Pierre, and has his slugging % up to .431.
I don't think that his recent play is a total fluke. Just look at his stats from last year at AAA. I say he can't be worse than Pierre.
Bring him up, and make Pierre a pinch runner.
