BOSTON, Mass. -- The Indians have activated first baseman Nick Swisher from the disabled list and placed DH Jason Giambi on the disabled list with a sore left knee.

Swisher just completed a two-game rehab assignment at Class AA Akron. He went 3-for-4 with two doubles and two RBI on Wednesday night for the RubberDucks.

The switch-hitting Swisher went on the disabled list on May 27 with a hyper-extended left knee. He received cortisone shot in both knees.

This is Giambi's third trip to the disabled list this year. He opened the season on the DL with a broken rib. A strained right calf put him on the DL for the second time, now comes an injury to his left knee.

Swisher, who was in Thursday night's lineup at DH, is hitting .211 (39-for-185) with 11 doubles, three homers and 19 RBI in 49 games.

Giambi, who played Wednesday against Kansas City, is hitting .128 (6-for-47) with two homers and 15 RBI.
