BALTIMORE — It didn't take long for ex-Orioles pitcher Dean Kremer to get revenge on his old ball club. Just under two weeks ago the 30-year-old righty was traded to the Minnesota Twins for an 18-year-old minor leaguer. After spending all but two games of his 7-year big league career with the O's, Kremer now donning a Twins uniform put on a clinic. Kremer tossed seven innings of one-hit ball, while surrendering just one run en route to a 9-5 Minnesota victory. That result was made possible by Kremer retiring 20 out of 22 Orioles hitters he faced, including each of the final 10.
