Bullpen implodes as O's top Sox

Boston Red Sox relief pitcher Craig Kimbrel reacts after allowing a run in the ninth inning against the Baltimore Orioles at Fenway Park.

There was good and bad in Chris Sale’s final start before the postseason. Sale went 4 2/3 innings, allowing three runs in the Boston Red Sox’ 10-3 loss to the Baltimore Orioles in the nightcap of a doubleheader at Fenway Park on Wednesday.

Sale struck out eight and allowed four hits, including a Trey Mancini RBI triple in the first and an Adam Jones RBI double in the fifth.

Boston (107-52) got an RBI triple from Tzu-Wei Lin, a run-scoring single from Blake Swihart, and scored a run on a fielding error.

The Red Sox’ bullpen struggled as Matt Barnes entered in the seventh inning of a 3-3 game and allowed three runs and four hits while retiring only one batter. Closer Craig Kimbrel also struggled, starting the ninth inning with a 6-3 deficit and then walking three batters and hitting another in a third of an inning. He was charged with four runs, all earned, and didn’t give up a hit.

Mancini drove in three runs for the Orioles (46-112). Tanner Scott (3-2) got the win.
