First baseman Derrek Lee has passed his physical and signed a one-year contract, which could pay him up to $10 million, including bonuses.
Lee, 35, will be made available to reporters in a conference call this afternoon. He's already returned home.
Lee hit .260 with 19 homers and 80 RBIs last season before undergoing surgery to repair a torn ligament in his right thumb.
In 170 career games against the American League, Lee has batted .311 (191-for-615) with 27 homers, 103 RBIs and a .530 slugging percentage.
Since the start of the 2000 season, Lee played more games (1,596) than anyone else in the National League despite appearing in only 50 in 2006 due to a broken right wrist. He boasts a .994 career fielding percentage in 1,788 games at first base.
With the addition of Lee, the Orioles now have 38 players on their 40-man roster. Reliever Kevin Gregg will be the 39th once his physical is completed.
