ATLANTA -- The Braves put right-hander John Thomson on the 15-day disabled list Friday after he left his last start with a blister.
Right-hander Lance Cormier was called up from Triple-A Richmond to replace Thomson, though the newcomer will actually make his first start Saturday in place of another ailing Atlanta pitcher.
Horacio Ramirez was struck in the forehead with a batted ball last Sunday and experienced dizziness when he tried to work out this week. Cormier will take Ramirez's turn in the rotation against the Boston Red Sox, making his first start in the big leagues since 2004.
Cormier, who was acquired from Arizona during the offseason, earned a spot in the Braves' bullpen out of spring training. But he was sent to the minors after posting a 6.10 ERA in 18 appearances and struggling with his control (17 walks in 20 2/3 innings).
The Braves don't plan to put Ramirez on the disabled list. The left-hander could be ready to start by next Thursday or the following weekend at the latest.
Thomson (2-6, 4.68 ERA) left Wednesday's start against the Florida Marlins when he developed a blister on his right middle finger.
"It's frustrating because I haven't had one in six years," he said.
