WASHINGTON (AP) -- Ronnie Belliard homered twice and drove in five runs, Tim Redding finally got a victory after nine consecutive no-decisions and the Washington Nationals beat the Houston Astros 10-0 Friday night.

Redding (7-3) allowed seven singles, walked none and struck out six in six innings. The Astros had hits in the first five innings, but Redding consistently wiggled out of trouble to record his first victory since May 19.

Austin Kearns also homered and drove in three runs for the Nationals, who had lost seven of eight.

Steven Shell worked three innings for his first career save as Washington earned its seventh shutout of the season, and second in three days.

The Astros have been blanked three times this season and have lost eight of 10 overall.

Houston starter Roy Oswalt left with a strained left hip after throwing 17 pitches during a scoreless first inning. The right-hander, who was making his first start since June 30 and had been bothered by pain in his hip, was removed in the second inning for a pinch hitter.

Nationals first baseman Dmitri Young left in the third with tightness in his lower back.

Washington took a 2-0 lead in the second. Jesus Flores singled with one out and Belliard hit a 1-0 pitch from Chad Paronto (0-1) into the left-field stands for his eighth homer.

Belliard hit a three-run drive for career homer No. 100 in Washington’s five-run fifth. Flores also had a two-run single in the inning.

It was Belliard’s second multihomer game of the season. He also hit two June 10 at Pittsburgh.

Kearns hit a two-run shot in the sixth to make it 10-0.
