According to the LA Times, the Dodgers have claimed second baseman Ronnie Belliard off waivers from the Nationals. Belliard is hitting .240 with 10 HR and 33 RBI in 77 games this season for the Nationals. It is safe to assume that the Dodgers were not going after Belliard, but they wanted to block the Diamondbacks from landing him because of Hudson's injury.
Belliard is locked up through 2009, but has an easy contract to move. He is making 1.9 million next season, so it is possible that they would move him.
