Lance Berkman aggravated his right shoulder during Tuesday's game against the Astros. Berkman was forced to leave the game after he felt a recurrence of discomfort when he grounded out in the fourth inning. "Honestly I thought I was going to be fine today," said Berkman. "When I got out there in the game, I took that swing. it's concerning to me, just because I don't want to do something and really hurt myself. It's like a pinch. When you go to accelerate, it's just there. it's like any kind of a strain. It doesn't feel good. Berkman will be examined by a doctor Wednesday and could receive an anti-inflammatory injection. He'll likely have to miss the next couple of games, but hopefully this doesn't become a lingering issue.
