BOSTON - Roger Bernadina doubled with two outs in the ninth, driving in Bryce Harper for the go-ahead run and the Washington Nationals held on for a 4-3 win over the Boston Red Sox on Sunday, completing a three-game sweep.
Danny Espinosa doubled twice and drove in two runs for the Nationals, who as a franchise had never won at Fenway Park entering the series.
Harper, Washington's rookie phenom, was out of the starting lineup because of tightness in his back. He pinch-hit for Tyler Moore with one out in the top of the ninth and drew a walk from Alfredo Aceves.
Aceves (0-4) struck out Jesus Flores for the second out, but Bernadina doubled to the right-field corner and came all the way from first, sliding safely into home to put the Nationals up 4-3.
Reliever Tom Gorzelanny (2-1) pitched a scoreless eighth and Tyler Clippard closed the game with his third save of the series, striking out Dustin Pedroia to end it.
