Roberts gets key hit again for Orioles

Brian Roberts had the decisive hit for the second consecutive game, a tiebreaking single in the eighth inning, and the Baltimore Orioles completed a three-game sweep of the Philadelphia Phillies with a 2-1 victory Sunday.

Roberts hit a run-scoring single to center field against Cole Hamels (4-3) that made it 2-1 and sent the Orioles to their fifth consecutive victory. Roberts hit a two-run home run with two outs in the ninth inning against Ryan Madson in a 6-5 win Saturday night.

The World Series champion Phillies have lost a season-high six games in a row, getting swept at home in consecutive interleague series by Toronto and Baltimore.

Philadelphia fell to 13-22 at home -- the Phillies are a major league-best 23-9 on the road.

Jim Johnson tossed a scoreless eighth inning and George Sherrill worked a perfect ninth for his 15th save.

Roberts’ single made a winner of starter Jeremy Guthrie (5-7) for the first time since May 25. Guthrie tossed three-hit ball over seven innings and gave up only Greg Dobbs’ fourth home run, in the second inning.

Robert Andino led off the eighth inning with a double and advanced to third on a groundout. Roberts lined a single and the Orioles were on their way toward matching their longest winning streak of the season.
