The Indians have sent righthander Sung-Wei Tseng, the No. 17 prospect in the Indians system entering the season, from Double-A Akron to high Class A Kinston after the 23-year-old struggled in nine relief appearances with the Aeros.
Tseng, who signed out of Taiwan in 2006 for $300,000, allowed 15 runs—including three homers—in 15 1/3 innings with Akron, giving him an 8.80 ERA. He had 12 strikeouts and six walks.
In a corresponding roster move, the Indians promoted righthanded reliever Erik Stiller from Kinston to Double-A. A nondrafted free agent out of Princeton, Stiller had a 2.79 ERA and a 27-9 K-BB ratio through 19 1/3 innings in his nine appearances.
