C Chris Wallace
A 16th-round pick out of the University of Houston in 2010, Wallace hit .251 last season in Double-A before a late-season promotion to Oklahoma City. Wallace slammed 20 home runs with 78 RBIs at two levels last season.
C Jason Jaramillo
The Oklahoma State product, a second-round pick in 2004, owns a career .235 average in 336 major league at bats but has spent the bulk of his career in the minors. Jamarillo is a career .264 hitter in 2,181 minor league at bats.
C Cody Clark
Clark hit .180 with four home runs as the backup catcher for the Royals' Triple-A team (Omaha) last season.
1B/OF Marc Krauss
A power hitter acquired in a trade with Arizona last July. In three full pro seasons, Krauss has slammed 61 home runs with 231 RBIs. Krauss batted .271 with 20 home runs, 79 RBIs last season, most of his at bats with two Double-A teams.
2B Jake Elmore
A 34th-round draft pick out of Arizona State (2008), Elmore made his major league debut last season with the Diamondbacks after hitting .344 at Triple-A Reno. Claimed off waivers by Houston, Elmore, a career .292 hitter in the minors, can also play shortstop and third base.
SS Jonathan Villar
One of the Astros' top prospects. Houston's potential shortstop of the future, Villar was selected a Texas League All-Star. The Dominican Republic native missed half the season with a hand injury but still slammed 11 home runs with 50 RBIs in Double-A.
3B/1B Brandon Laird
Laird was claimed off waivers during the offseason. Three years ago, he slammed 25 home runs with 102 RBIs in the Yankees system. He's the younger brother of veteran major league catcher Gerald Laird, who also played for the RedHawks.
