ARLINGTON -- Astros catcher Jason Castro, who missed Monday's game with a mysterious pain in his left armpit, was improved Tuesday and did some hitting in the batting cage. Castro said he felt well enough that he was available to pinch-hit.
The cause of the pain still isn't known, even after Castro visited doctors Monday. He has been taking some anti-inflammatory medicine and some antibiotics, which seem to be working.
"I saw a few doctors yesterday and without getting into some in-depth testing, they can only guess to what it is," he said. "Everything seems pretty minor what their guesses are. They way I came to the field and felt today, it's really not worth trying to pinpoint it, I guess, just stick with what we're doing right and the progress."
The injury comes at a bad time for Castro, who was hitting .462 (6-for-13) in his last three games after getting moved into the No. 2 spot in the batting order.
"Hopefully, it won't be too much longer now," he said. "I'm pretty happy about the progress from yesterday to today."
