ARLINGTON -- While the Astros were forced to play without starting center fielder Carlos Gomez for a second consecutive day on Monday because of a mild intercostal strain, starting catcher Jason Castro (strained right quad) progressed to the point where he could be activated any day.
Meanwhile, versatile infielder Marwin Gonzalez is dealing with a swollen left index finger, an injury sustained sliding into the base on Saturday in Anaheim, and is considered day to day.
Castro, who's been out two weeks, on Monday worked on agility drills to test the leg, and also caught a bullpen session.
