According to Baseball America, six of the Houston Astros' top 20 prospects are on the RedHawks' roster.
No. 1 prospect — outfielder Jonathan Singleton — must serve a 50-game suspension to start the season for violating minor league baseball's drug policy, according to ESPN.com.
Fifteen players spent time with the RedHawks last season, but only five originally were drafted or signed by the Astros.
Nearly half of the current roster (12 players) came via trades, including five players acquired since Jeff Luhnow was named Astros general manager a year ago. Half the roster wasn't with the organization before last season.

Talented Staff: Eight starters will piggyback in a four-man rotation. Jordan Lyles started 25 games for the Astros. John Ely was the PCL Pitcher of the Year last season as a member of the Dodgers organization. Jarred Cosart is one of the Astros' top prospects who eventually could become a fixture in Houston's rotation. Jose Cisnero possesses dazzling stuff and might emerge as the best of the group. Jose Valdez recorded 21 saves with the RedHawks last season.
9 Jason Jaramillo (30); Sacramento (AAA)
19 Cody Clark (31); Omaha (AAA)
Two veterans: Cody Clark and Jason Jaramillo are veteran stopgaps while catchers develop at lower levels. Jaramillo, who played at Oklahoma State, hit .237 with Double-A and Triple-A teams in the Brewers and A's systems last year. Clark played a backup role for the Royals' Triple-A team in Omaha.
