Apparently it's Astros Day for Jonathan Mayo, who posted his 10 Astros Prospects to watch. They are:
Jay Austin
Jason Castro
Collin DeLome
Jon Gaston
Chris Johnson
Chia-Jen Lo
Jordan Lyles
Tommy Manzella
Jiovanni Mier
Ross Seaton
There were some subtractions from last year's list:
Felipe Paulino
Bud Norris
Brian Bogusevic:
As a guy who has the skills to play an outfield corner well (that pitching arm works from the outfield too), he will need to show he can hit for more power than he did last year.
