Sowers pitched 5 1/3 innings and wound up with a no-decision as the Indians won 4-3 on Victor Martinez's RBI single in the ninth inning. The left-hander, who was demoted to the minors last season after starting the year in Cleveland's rotation, was pleased with the performance in his short stint.
"I did everything I could," said Sowers, who was beaten out for the No. 5 starter's job in training camp by Cliff Lee. "I was able to keep us in the game.
"I feel like I restored some of that lost confidence."
To fill the roster spot, the Indians recalled outfielder Brad Snyder from Buffalo. He was batting .236 with four homers and 10 RBIs in 20 games for the Bisons.
Although he would probably start for many other teams, Sowers is currently on the fringe of Cleveland's deep starting staff. He and Aaron Laffey finished behind Lee, who is off to a great start at 4-0 with a 0.28 ERA.
Laffey is expected to be recalled on Monday to start the finale of Cleveland's four-game series with New York. He could stay with the club for an extended period because right-hander Jake Westbrook is going to miss at least four weeks with a strained back muscle.
