The Toronto Blue Jays have activated right-hander Jesse Litsch from the 60-day disabled list and optioned left-handed reliever Rommie Lewis to triple-A Las Vegas.
The moves were announced before Wednesday night's game against Tampa Bay.
Litsch, who had elbow ligament replacement surgery in June 2009, will replace left-hander Brian Tallet in the rotation and is scheduled to make his first start of the season Sunday at Colorado.
Tallet will move to the bullpen.
Also, right-hander Scott Richmond, out with a right shoulder injury, will make the first of three scheduled rehab starts with single-A Dunedin on Thursday.
