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.

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.
INF Jose Martinez
Combined to hit .289 with 13 home runs and 84 RBIs last season with Double-A Corpus Christi and Triple-A Oklahoma City but probably will play a utility role this season.
INF. Ruben Sosa
The Oklahoma City University product led the NAIA in stolen bases (41) two years ago. A 23rd round draft pick in 2011, Sosa hit .261 at two lower levels last season.
LF Trevor Crowe

CF Robbie Grossman
One of the Astros' top 20 prospects, Grossman last July was acquired from Pittsburgh for pitcher Wandy Rodriguez. Grossman hit .266 in Double-A last season. Two years ago, Grossman became the first player in the minors since Nick Swisher in 2004 to score 100 runs and draw 100 walks.
RF Jimmy Paredes
A converted infielder. The Astros are trying to find a position for a player who last season hit .318 and ranked in the top five in the PCL in hits, runs and stolen bases. The Dominican Republic native is a career .290 hitter in the minors with 151 stolen bases.
OF Che-Hsuan Lin
Claimed off waivers from the Red Sox in the offseason, the Taiwan native has 147 career minor league stolen bases, including 25 or more stolen bases three of the past four seasons. Lin is a career .257 hitter in 633 minor league games.
