Here is the minor league report for the 2010 Round Rock Express, the Triple-A affiliate for the Houston Astros.

The key name to note on the roster is catcher Jason Castro. He gets high marks for his defense with his offense coming on strong. He has a .295 minor league average with 12 home runs in 584 at bats. He has shown a good eye at the plate with 77 walks against only 108 strikeouts. I would expect the Astros to have him spend most of the season in Triple-A with a September call up.

How they rank:

Baseball America: Castro (1)
Keith Law: Castro (2)
John Sickels: Castro (1)
