Blog post by Baseball America on the first round picks who have already signed (12 of them), and who have already made their pro debut (10). Jiovanni Mier, of course, has done both of those things. What did BA say?
The top prep shortstop taken in the draft, Mier has gotten off to probably the hottest start of any of the ‘09 first rounders. The Astros dispatched him to Rookie-level Greeneville of the Appalachian League afer signing him for $1,358,000, and Mier, whose bat was his biggest question mark, has handled the transition to pro ball nicely, hitting .323/.425/.516 through 62 at-bats. His four triples are tied for the league lead, while his 13 RBIs are good for the team lead. Mier has already had seven multi-hit games in 15 starts and is currently riding a five-game hitting streak.
