As the Astros and Nationals get underway, just a few quick injury updates:

>>> Tom Gorzelanny’s right ankle remained sore today after he sprained it Sunday afternoon in a collision at home plate. Gorzelanny iced his ankle this morning and in the afternoon and said it was “way too soon” to know if he could make his next scheduled start. Since the Nationals have an off day both Thursday and next Monday, as Manager Davey Johnson pointed out, they could skip Gorzelanny without forcing any other starter to pitch on irregular rest.

Gorzelanny received an x-ray on his ankle, he said, and the results were negative.

>>> Ivan Rodriguez said he felt no pain as he hit off a tee and took soft toss today, his best progress yet as he rehabs from a strained oblique muscle that landed him on the 15-day disabled list, retroactive to July 7. Rodriguez also said he plans to take full batting practice and hopes to return Friday, the first day he is eligible to come off the disabled list.

“I’m pretty much right there,” Rodriguez said. “The way I feel right now is 10 times better than I was just five, six days ago.”

Johnson, though, seemed a little more apprehensive about a Friday return for Rodriguez. “First of all, he’s got to get through a full workout,” Johnson said. “I don’t think he’ll be able to do that while we’re [in Houston through Thursday]. As early as yesterday, he had problems still swinging. He was smiling today and sticking close to me, so I guess he must have had a good time in the cage.”

>>> The Nationals officially activated Jerry Hairston from the 15-day disabled list after he missed 14 games with a broken bone in his left wrist. Hairston said he felt comfortable Saturday in his final rehab game at Class AAA Syracuse. “I really got the chance to let the bat go, see how I feel,” Hairston said. “It feels good, man. I’m ready to go. It’s a non-issue, really.” Hairston will wear a small shield over his left hand, but said it would not affect him.
