Humberto Quintero said he plans to rejoin the Astros after the break following an eight-game rehab assignment with Triple-A Oklahoma City.
Quintero, who went on the disabled list on May 28 with a right ankle sprain, said he plans to join Oklahoma City in Memphis on Friday, exactly one week after J.R. Towles took a foul tip off the chin and received 11 stitches.
Quintero participated in catching drills before team batting practice on Tuesday.
"Everything's good," Quintero said. "I feel 100 percent. I feel like I'm in good shape."
Carlos Corporan has spelled Towles and Quintero, catching in 15 games this month, including Tuesday night against the Rangers. The Astros have been so depleted at the position they brought another catcher, Brian Esposito, to the Majors on June 25.
