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

Roberts hit an RBI single to center off Cole Hamels (4-3) that made it 2-1 and sent the Orioles to their fifth straight win. Roberts hit a two-run homer with two outs in the ninth off Ryan Madson in a 6-5 victory Saturday night.

The World Series champion Phillies have lost a season-high six straight, 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.
