The Washington Nationals didn't score any runs for rookie sensation Stephen Strasburg, but their offense snapped out of its slump in time to rally for three runs off Mets closer Francisco Rodriguez in the ninth and beat the New York Mets 6-5 on Saturday at Nationals Park.

Adam Dunn laced a two-run double to center to tie it, and Ivan Rodriguez won it with an RBI single to right to complete Washington's 14th comeback victory and its fourth walk-off win.

Francisco Rodriguez (2-2) recorded only one out and allowed three hits and three walks in his fourth blown save of the season.

The Mets led 2-0 when Strasburg left after five innings, having allowed two runs on four hits. The Nationals haven't scored a run while Strasburg was in the game in any of his last three starts, but they scored six runs over the last four innings Saturday.

Nationals closer Matt Capps (2-3) pitched a perfect ninth for the win.

Dunn and Ivan Rodriguez each went 3-for-5 with two RBIs.

Washington's rally spoiled another solid outing from knuckleballer R.A. Dickey, who allowed two unearned runs on six hits over seven innings.

The Mets got two hits apiece from David Wright, Ike Davis and Josh Thole. Thole drove in two runs.
