UPDATE: Houston made two more roster moves before Wednesday's game, promoting David Carpenter from Oklahoma City and demoting catcher Brian Esposito. They also transferred Alberto Arias to the 60-day disabled list, which opened up a spot on the 40-man roster for them to claim outfielder Luis Durango from the Padres and send him to Oklahoma City.
After Tuesday's game against the Texas Rangers, Houston made a pair of roster moves. Backup outfielder Jason Bourgeois was placed on the disabled list with a strained quadriceps muscle. He apparently suffered the injury in the fifth inning of the game after hitting into a 5-4-3 double play to end the inning.
It's the second time this season that Bourgeois is spending time on the disabled list and he will be replaced on the 25-man roster by Oklahoma City outfielder Brian Bogusevic, who's now on his second stint with the big league team this season.
Bogusevic hit .222/.323/.222 in 31 plate appearances over his first 25 games with Houston this season. Bourgeois was hitting .353/.371/.422 in 105 plate appearances in 45 games.
The Astros also made another roster move of sorts, sending Humberto Quintero on a rehab assignment to Triple-A Oklahoma City. Quintero suffered a high ankle sprain in a collision at home plate on May 28 and has been on the disabled list since. The plan for his rehab stint, according to the Chronicle's Steve Campbell, is for Q to play five innings at a time, then take a day off before playing more to test the ankle.
