OAKLAND, Calif. – John Jaso doubled in pinch-runner Nick Punto with two outs in the 10th inning to lift the Oakland Athletics to a 4-3 win over the Washington Nationals on Saturday night.

The A's scored twice in the ninth off Nationals' closer Rafael Soriano to force extras and storm back for their third walk-off win this season after being limited to two hits over the first eight innings.

Alberto Callaspo singled off reliever Drew Storen (2-1) to lead off the 10th before Punto replaced him at first. Storen retired Eric Sogard and Derek Norris before Jaso hit a towering fly ball that ricocheted off the scoreboard in right field as Punto rounded the bases and scored.

Sean Doolittle (1-2) pitched one inning for the win to help Oakland overcome an uneven outing by starter Sonny Gray.

Jaso hit a solo shot in the third inning.
