WASHINGTON — The Washington Nationals are prospering in their new ballpark.

Tim Redding allowed one run over 6 1-3 innings, Boone homered and the Washington Nationals beat the Pittsburgh Pirates 5-2 on Sunday.

Redding (4-2) closed out an 11-game homestand, Washington's longest of the season, by helping the Nationals to their sixth victory in seven games. Washington finished the homestand 8-3.

"We were (6-15 overall) coming into this homestand. We had to come back in here, save face and protect our park," said Redding.

Washington begins a three-game series in Houston on Tuesday, then concludes a stretch of 14 of 17 games at National Park by hosting Florida next weekend.

"It's encouraging. We had a tremendous homestand. We won three series and that's great — not only for our team but for our fans. ... They got a good taste of our team," Washington manager Manny Acta said. "And if you look at it, we're still not hitting the way we're capable of and we were able to have such a tremendous homestand."

Redding, who has twice as many wins as any other Nationals starting pitcher, allowed six hits, walked none and struck out five.

"He pounded the strike zone with his fastball and was very aggressive, especially with the first pitch. ... And he kept his pitch count low, which gave him an opportunity to go all the way to the seventh," Acta said.

Redding departed after Adam LaRoche's one-out double in the seventh put runners at second and third. Reliever Saul Rivera induced comebackers to the mound from Jose Bautista and pinch-hitter Doug Mientkiewicz to escape the jam.

"It didn't go unnoticed. ... How huge was that? That was the game right there," Acta said.

LaRoche had three hits, including a homer, and two RBIs for the Pirates, who have lost seven of 10 games and 13 of 18. It was the second homer of the year for LaRoche, who hit 21 home runs last year and hadn't connected since April 9.

"He's been swinging better," Pirates manager John Russell said of LaRoche, who increased his average to .202, his first time above .200 since opening day. "He's hit some balls at people. I saw glimmers of it a couple of weeks ago, and I see his confidence building."

RBI singles by Nick Johnson and Austin Kearns staked Redding to a 2-0 first-inning lead.
