HOUSTON -

Houston Astros General Manager Jeff Luhnow announced today that the club has claimed infielder Steve Pearce (#13) off waivers from the Baltimore Orioles. Pearce will report to the Major League club tomorrow, at which time the Astros will make a corresponding roster move.

The Astros also officially purchased the contract of right-handed pitcher Armando Galarraga (#30) from Triple A Oklahoma City. To make room for Galarraga on the active roster, the club optioned left-handed pitcher Fernando Abad to Triple A. To make room for Pearce and Galarraga on the 40-man roster, the Astros outrighted right-handed pitchers Enerio Del Rosario and Aneury Rodriguez to Oklahoma City. Both players cleared waivers and will join the RedHawks.

Pearce, 28, was hitting .254 (18x71) with four doubles, three home runs and 14 RBI in 28 games for Baltimore this season. He was designated for assignment last Sunday. The right-handed hitting corner infielder and outfielder began the regular season with Triple A Scranton/Wilkes-Barre in the New York Yankees organization, where he hit .318 (61x192) with 11 home runs and 30 RBI in 53 games before being traded to Baltimore on June 2. Pearce has spent parts of each of the last six seasons in the Majors with Pittsburgh (2007-11) and Baltimore (2012) and has played in 213 Major League games.

Galarraga, 30, owns a 3-2 record and a 3.97 ERA (21ER/47.2IP) in 10 starts in the Astros minor league system this season (nine with Triple A OKC, one with Class A Lexington). The veteran right-hander was signed by Houston as a minor league free agent on May 21. He began his year in the Baltimore organization before being released following Spring Training. Galarraga, who will start for Houston tonight, owns a 26-30 Major League record with a 4.69 ERA (270ER/528IP) in 95 games (86 starts) across parts of five seasons with Texas (2007), Detroit (2008-10) and Arizona (2011).

Abad, 26, has posted a 3.86 ERA (10ER/23.1IP) in 30 appearances for the Astros this season. This is his second option to Oklahoma City in 2012, where he owns a 1-0 record with two saves and a 0.00 ERA (0ER/9.2IP) in seven appearances. Abad owns a career record of 1-5 with a 4.65 ERA (32ER/62IP) in 81 appearances over the last three seasons with Houston.

Del Rosario, 26, was optioned to Oklahoma City yesterday before being outrighted today. He owns a 7.80 ERA (13ER/15IP) in 15 relief appearances for the Astros this season. Other than a month-long DL stint, Del Rosario spent the entire 2011 campaign on Houston’s roster, posting a 4.58 ERA (27ER/53IP) in 54 relief appearances. He has a career 1-4 record with a 5.19 ERA (45ER/78IP) in 80 Major League appearances with Cincinnati (2010) and Houston (2010-12).

Rodriguez, 24, has spent the majority of his season with Triple A OKC, where’s gone 3-7 with a 6.67 ERA (62ER/83.2IP) in 23 games (13 starts). He made one start for the Astros on May 8 vs. MIA, tossing 6.0 innings, allowing two runs on two hits. The Astros 2010 Rule 5 Draft pick spent all of the 2011 season with the Astros, posting a 1-6 record and a 5.27 ERA (50ER/85.1IP) in 43 appearances, including eight starts.

With the moves, the Astros 40-man roster remains full.
