Barrett, batting .256 with nine homers and 29 RBIs, has had problems defensively and also been involved in two dugout exchanges this month with Cubs pitchers.

He and Carlos Zambrano got into a skirmish in the dugout June 1 and it carried over into the clubhouse where Barrett got a black eye and needed stitches in his lip.

Less than two weeks later, Barrett and pitcher Rich Hill had an exchange in the dugout during a game against the Seattle Mariners.

Barrett was the central figure in a brawl with the White Sox last season when he punched A.J. Pierzynski in the jaw after he'd been run over at the plate.

Barrett will be eligible for free agency after this season.

Koyie Hill has become Zambrano's catcher the last three starts. Henry Blanco, who was supposed to be Barrett's backup this season, has been on the disabled list with neck problems.
