Baseball America posted a Prospects of the NL Central article. Now, about those Astros:
Prospect Star of Camp: Sam Gervacio
In a relatively unsettled Astros' bullpen there is room for Gervacio to move into a more prominent role if he keeps pitching like he's been pitching.
Keep an Eye on: Chris Johnson
He'll have to keep hitting as the Astros will be looking for a roster spot for Lance Berkman when he returns from the disabled list in the not-too-distant future.
Rough Spring: Brian Bogusevic
Bogusevic will have to hit for more power to be a big leaguer, but a .071/.071/.143 line in 14 at-bats didn't give him a chance to make much of an impression this spring.
