ARLINGTON -- The Astros have essentially been playing with one catcher since J.R. Towles tweaked a muscle on the back of his right leg running the bases on Wednesday. Towles hasn't played since, meaning Carlos Corporan started his sixth game in a row Tuesday.
"[Towles] said he was better, but it was hard to stick him in the lineup because you could lose your catcher," Astros manager Brad Mills said. "Ideally for him, he probably won't be able to start until Friday. We'll see how it goes."
Towles said Tuesday he feels his strength is getting better, but it's still painful for him to perform short, quick movements. He feels most of his discomfort when he has to come out of his crouch to field a ball and throw it to a base.
Towles fouled a ball off his left ankle Wednesday and later in the game scored from second base on a single by Michael Bourn, injuring his leg.
"I was talking with [head athletic trainer] Nate [Lucero], and he said maybe because my ankle was hurting at the time, my right side was trying to compensate for the left side," said Towles, who has been treating the area with ice, heat and massage.
