Harper hits 25th HR, Roark stops skid, Nats beat Brewers 7-3

MILWAUKEE -- Tanner Roark put an end to a seven-start winless streak, the longest in a season of his big league career.

Bryce Harper tied for the NL lead with his 25th home run, Roark pitched eight scoreless innings and the Washington Nationals beat the Milwaukee Brewers 7-3 on Wednesday.

Roark (4-12), the NL leader in losses, allowed three hits, struck out a season-high 11 and walked one, helping the Nationals avoided being swept in the three-game series.

Hernan Perez hit a three-run homer in the ninth off Sammy Solis and Brad Miller reached on an infield hit with two outs before Kelvin Herrera retired Manny Pina on a soft liner to third.

Peralta, recalled from Class A Wisconsin before the game, gave up seven runs, four hits and four walks in six innings.
