Bautista powers Bucs’ win

Washington’s winning streak was snapped at four games.

WASHINGTON (AP) — Jose Bautista homered twice and drove in four runs and the Pittsburgh Pirates defeated Washington 11-4 Friday night, ending the Nationals’ winning streak at a season-high four games.

Ryan Doumit and Chris Gomez had two RBIs apiece for the Pirates, who have won three of five.

The game was delayed 25 minutes in the bottom of the fourth when rows of lights along the left- and right-field lines went dark. Umpires huddled with Nationals Park operations staff before the teams retreated to their dugouts to wait out the power failure.

Damaso Marte (2-0) pitched two hitless innings, and the Pirates bullpen gave up one hit in five innings.

Pittsburgh took a 6-0 lead in the second, sending nine men to the plate and breaking John Lannan’s scoreless streak at a Nationals-record 21 innings.

Nate McLouth led off with a double and Jason Bay drew a one-out walk before consecutive run-scoring singles to center by Doumit and Xavier Nady. Doug Mientkiewicz followed with a fielder’s choice grounder to short, but second baseman Felipe Lopez mishandled Cristian Guzman’s throw and Doumit scored. Bautista then ripped Lannan’s 1-2 pitch over the center-field wall for his second homer of the season.

Lannan (2-3) left after allowing six runs — five earned — on six hits and two walks in three innings.

Lopez hit an RBI double in the third, but Doumit’s run-scoring single in the fourth made it 7-1.

Pirates starter Phil Dumatrait retired the first eight hitters, but struggled after the lighting malfunction, which followed Ryan Zimmerman’s leadoff infield single in the fourth. The left-hander allowed a one-out double to Lastings Milledge and walked Austin Kearns to load the bases, then allowed a Wily Mo Pena sacrifice fly and a two-run double by Wil Nieves.

Bautista added a fifth-inning solo shot off Mike O’Connor for his second career two-homer game.

Dumatrait went four innings, giving up four runs on six hits, walking one and striking out four.

Gomez added a two-run single in the seventh, making it 10-4. Bay had an RBI double in the eighth.
