A.J. Burnett left his start after four innings because of a sore right elbow. Burnett, who signed a five-year, $55 million deal with the Blue Jays in the offseason after spending seven seasons with the Florida Marlins, began the season on the DL after scar tissue broke off in his elbow March 18 during spring training. Blue Jays spokesman Jay Stenhouse said it was "consistent with what (Burnett) experienced in spring training." But Burnett will be examined by Dr. James Andrews in Birmingham, Alabama. The scar tissue is left over from elbow ligament replacement surgery three years ago. "Something wasn't right," Burnett said. "It's pretty frustrating. I feel about two inches tall."
