Chicago, IL (Sports Network) - Matt Wieters collected two hits and drove in two runs in support of seven strong innings from Brian Matusz, as Baltimore slowed down Chicago, 4-2, in the middle session of a three-game set.
Brian Roberts added a solo home run and Felix Pie singled twice and scored for the Orioles, who halted a two-game slide.
Matusz (6-12) received enough run support to pick up the win after allowing a lone run on just three hits, while walking one and fanning five. Koji Uehara gave up a run in the ninth but hung on to earn his second save for the visitors, who lead the season series, 4-2.
Mark Buehrle (12-10) was saddled with the loss after permitting four runs on six hits and four walks in seven innings for the White Sox, who fell four games behind front-running Minnesota in the AL Central.
Uehara took over with a 4-1 lead and set down the fist two batters before Paul Konerko singled and scored on a Carlos Quentin triple. The right-hander then struck out A.J. Pierzynski to end the game and preserve the win.
The Orioles broke up a scoreless game in the fifth when Pie walked to open the frame and scored when Weiters doubled into the left field corner. Weiters then advanced to third on a ground out and scored on a two-out single to left by Corey Patterson.
Ty Wigginton led off the sixth with a walk, moved station to station on a ground out and a Pie single and scored on Weiter's sacrifice fly to deep center to extend the visitors lead to 3-0.
Chicago got on the board in the home half on a solo home run from Gordon Beckham, who left the yard for a second straight game. However, Roberts one- out long ball in the next half inning put the Birds back on top by three.
Mike Gonzalez worked a scoreless eighth inning to get the game to Uehara.
