Nearly all of them were either available to play on Wednesday or, in the case of the injured starting pitchers, in better shape to make starts before the end of the season.
Edgar Gonzalez, set to start Friday in Milwaukee, came through his bullpen session without any major issues with his hamstring. Fernando Abad, who left Monday's game with a right oblique strain, felt better on Wednesday and could be in line to pitch in the Astros' final series in Chicago.
The injured position players are also getting better.
Third baseman Matt Dominguez was back in the clubhouse after missing the last two games with flu-like symptoms. He took some early hitting before Wednesday's game and could be available to pinch-hit.
Infielder Marwin Gonzalez sprained his left ankle in Monday's game, but took full batting practice on Wednesday and was available off the bench.
Outfielder J.D. Martinez had surgery on Wednesday to remove the hook of the hamate bone in his left hand, a fairly common procedure among baseball players.
The procedure was performed by Dr. Tom Mehlhoff at the Texas Orthopedic Hospital. Martinez is expected to be unable to perform baseball activities for four to six weeks.
"I haven't found out how it came out but we're assuming everything went well," DeFrancesco said. "It should be four to six weeks before he can get back out swinging again."
