Orioles 5, Phillies 4 (10): Matt Wieters plated Adam Jones with an RBI double in the 10th inning as host Baltimore kept Cliff Lee winless and took two of three from reeling Philadelphia.

After Jones reached on third baseman Ty Wigginton's fielding error, Wieters brought him home with a double to right field off Joe Savery (0-1). Baltimore, which posted a 6-4 triumph in 12 innings on Saturday, secured its league-best ninth victory in extra frames this season.

Philadelphia, which suffered its league-high seventh walk-off loss, suffered its eighth loss in nine games.

Darren O'Day (4-0) picked up the win after retiring the side in order in the 10th inning.

Staked to a 4-1 lead, Lee was unable to hold the advantage as he permitted a three-run homer just inside the left-field foul pole to Steve Tolleson in the fourth inning. The southpaw finished the inning, but exited after yielding four runs on seven hits in six innings.

Hunter Pence had a two-run single and veteran Jim Thome added an RBI single for the Phillies.
