According to Dan Connolly and Jeff Zrebiec of the Baltimore Sun, four Orioles players have cleared waivers: Aubrey Huff, Jay Payton, Kevin Millar, and Jamie Walker. Walker we already knew about. The Orioles can now trade any of the four to any team.
I had guessed that Huff would not clear waivers, on account of his .910 OPS (10th in the AL). However, the $10.1MM owed to Huff through ’09 proved too much for the other 29 teams. His limited defensive abilities probably also played a role.
The Sun also mentioned that George Sherrill was claimed by an AL team and pulled back, which was expected.
