The team activated shortstop Carlos Guillen from the 15-day disabled list before Friday night's game against the Mariners. Guillen was placed on the disabled list on Aug. 11 with a sore knee. He has been limited to 81 games this season after tearing his right ACL last Sept. 11. An All-Star last year, Guillen has hit .318 in 2005 with five homers and 23 RBI.
