TORONTO — The Oakland Athletics placed catcher Kurt Suzuki on the 15-day disabled list Friday with a strained muscle in his side, and optioned outfielder Matt Carson to Triple-A.

Suzuki, a Baldwin High alum from Maui, was put on the disabled list retroactive to April 24.

Left-hander Trevor Cahill was added to the roster to start against the Blue Jays Friday, in place of left-hander Brett Anderson (elbow), and catcher Josh Donaldson had his contract purchased from Triple-A. Pitcher Joey Devine (right elbow) was transferred to the 60-day DL to make room for Donaldson.

Oakland also announced that right-hander Justin Duchscherer, who left in the fourth inning of Thursday's game with a sore left hip, will visit Dr. Thomas Byrd in Nashville on Monday. Duchscherer (2-1) missed all of last season after having elbow surgery and was limited to 17 games in 2007 with a right hip injury that required two surgeries, one that year and another in 2008.
