The Astros have placed starting 2B Kaz Matsui on the 15-day disabled list with a irritated disc. Matsui has played in 85 games for the Astros this season and he is 96 for 337 (.285 avg, .763 OPS) with 49 runs scored, 5 homers, 28 RBIs and 19 stolen bases. Mark Loretta will likely take over for Matsui at 2B and he’s a solid, steady veteran. Loretta has played in 80 games for the Astros this season and he is 57 for 211 (.270 avg, .731 OPS) with 23 runs scored, 4 homers and 33 RBIs. The Astros have recalled 28-year old righty swinging catcher/1B J.R. House from AAA to replace Matsui on the active roster. House has played in 119 games in AAA ball this season and he is 128 for 422 (.303 avg, .853 OPS) with 61 runs scored, 17 homers and 55 RBIs. House has also played in 1 game this season for the Astros and he is 0 for 1 with a RBI. House hasn’t had much of an opportunity to show what he can do in the majors but this could be his shot. House has played in 30 games in his major league career and he is 10 for 58 (.172 avg, .592 OPS) with 6 runs scored, 3 homers and 4 RBIs.
