Rookie Brian Matusz pitched eight innings, and the Baltimore Orioles used a four-run seventh to defeat Colby Lewis and the skidding Texas Rangers 4-0 on Thursday night.
Matusz (5-12) gave up five hits, walked one and struck out six. Only two Rangers reached second base and none advanced to third.
It was the fourth straight defeat for the Rangers, who were coming off a three-game sweep in Tampa Bay. Texas received a fine pitching performance from Lewis (9-10) until the seventh, when Baltimore did all its scoring on five hits.
After Corey Patterson hit an RBI single, Brian Roberts doubled in two runs and scored on a single by Nick Markakis.
The Orioles improved to 11-6 under Buck Showalter, whose previous managerial job was with Texas from 2003-06.
