Slugger Jason Giambi is expected to rejoin the Yankees today to continue his rehabilitation.

The five-time all-star has not played since July 23. He had a benign tumor diagnosed last month.

Giambi is hoping to again play before the regular season ends. The team has not set a timetable for his return. Giambi has been working out at the Yankees' complex in Tampa. He took batting practice Sunday for the first time since being diagnosed. The former AL most valuable player has hit .221 with 11 home runs and 36 RBI.

* JACKSON RELEASED: Reliever Mike Jackson, whose 1,005 career appearances rank eighth all-time among pitchers, was put on waivers by the White Sox for the purpose of giving him his unconditional release.

Jackson, 39, was 2-0 with a 5.01 ERA in 45 appearances this season, his 19th in the majors. The right-hander is 62-67 with a 3.42 ERA and 142 saves in his career.

The White Sox called up RHP Felix Diaz from Class AAA Charlotte for the third time this season. Diaz will start today against Oakland. Jason Grilli will pitch tomorrow because Freddy Garcia has a sore muscle in his forearm. The White Sox are expected to decide this week whether to put Garcia on the disabled list.

* SIZEMORE SENT DOWN: The Indians sent OF Grady Sizemore back to Class AAA Buffalo to make room for OF Ryan Ludwick.
