Berkman has knee drained ... again

It's Opening Day at Minute Maid Park and pitcher Roy Oswalt has made his franchise-record eighth consecutive Opening Day start.

Despite beginning the season on the disabled list (DL), teammate Lance Berkman received a "big round of applause as he gingerly walks onto field..." as tweeted by MLB's Brian McTaggert.

Berkman, who missed 26 games in 2009, is eligible to return from the DL Saturday, however, that may be overly optimistic.

According to Bernardo Fallas of the Houston Chronicle, Berkman had his knee drained for a fifth time today and he's expected to get a cortisone shot.
