Nate McLouth, J.J. Hardy and Chris Davis all homered Sunday, powering the Baltimore Orioles to a 6-3 win and series sweep of Boston. McLouth\'s shot came as he was leading off the first inning and the O\'s never trailed after that. Jim Thome provided a pair of run-scoring singles in Baltimore\'s fourth straight victory, which allowed the O\'s to hang onto at least a share of the American League East league. Joe Saunders (3-3) earned the win with 7 1/3 solid innings, yielding three runs on eight hits with no walks and five strikeouts. Bosox starter Zach Stewart (1-4) was touched for for five runs on seven hits in just 2 2/3 innings. Daniel Nava and Cody Ross homered as the Red Sox reached 90 losses for the first time since 1966.
