"Berkman drops appeal; Astros slugger serving two-game ban beginning Tuesday": MLB.com provides this report.

And The Houston Chronicle reports that "Berkman drops appeal, won't play 2 games against A's."

The suspension arises from Houston Astros first baseman Lance Berkman's ejection on June 5, 2007 by third base umpire Ed Rapuano in the eighth inning. The Astros defeated the Colorado Rockies in that game by a score of 4-1.
