Boston, MA (Sports Network) - Adam Jones hit a three-run homer off of Darnell McDonald in the top of the 17th inning on Sunday and the Orioles outlasted the Red Sox, 9-6, to sweep a three-game series.

McDonald (0-1), an outfielder, entered the game as a pinch-runner in the eighth inning and scored the tying run, then took the mound in the 17th in support of a spent Red Sox bullpen.

Baltimore, which has won five games in a row and 11 of 13 overall, took advantage. J.J. Hardy doubled and Nick Markakis walked in front of Jones, who belted a 1-1 offering high over the wall in left.

Chris Davis (1-0) went 0-for-8 with five strikeouts as a designated hitter before tossing two scoreless innings of relief to earn the first win of his career.

The Red Sox nearly won the marathon in the 16th inning when Marlon Byrd reached on an error by third baseman Wilson Betemit and Mike Aviles followed with a deep fly to center off of Davis. The ball fell in for a double but Byrd was thrown out at the plate by Hardy, who hit two home runs earlier in the game.

Boston has lost five straight overall and 10 of its last 11 games at Fenway Park.
