OAKLAND -- John Jaso said it was his biggest night in an A's uniform, and by the end of the A's 4-3, 10-inning win over Washington on Saturday, it was certainly his messiest, too.

Jaso's 10th-inning double off the right field wall scored Nick Punto from first base with the game-winner, earning Jaso a whipped cream pie in the face, shoulders and torso, the Oakland symbol of late-inning success.

The catcher had already homered and started a two-run ninth-inning rally with a single before launching the double that had the A's swarming him between second base and the pitcher's mound.

The A's improved to 22-15 after one of the more improbable wins of the season.

Oakland had just three base runners in the first eight innings, but Jaso, Jed Lowrie and Josh Donaldson combined to rip Nationals closer Rafael Soriano for two runs to tie it. Given that Soriano had a streak of 19 consecutive saves and a run of 25 consecutive scoreless innings, that was whipped cream-worthy all by itself.

"It's funny how the game changes," Jaso said. "We were hitting the ball hard against their starter (Tanner Roark), too, but everything was being caught. The momentum changed right there."

Soriano was replaced in the 10th by Drew Storen, a pitcher who throws as hard as anyone in the Nationals bullpen. Jaso prepared for that by altering his batting stance a bit.

"He's going to come at me harder, I knew he had a little more velo than the other guys," Jaso said. "So I opened up to get a better look at the fastball. I wanted a fastball."

He got one, slamming a rocket to the wall, a ball Jaso said he "thought was hit harder than either of my other two homers." (He also homered in the series opener Friday). Right fielder Nate McLough made a desperation leap, came close, but didn't get the ball which bounded back toward the infield as Jaso and the A's watched pinch-runner Punto race home.

"Jaso's already had some big, big hits for us," winning pitcher Sean Doolittle said. "He's working long at-bats. He's seeing a ton of pitches. And now he's driving the ball all over the place. When you add someone like that to a lineup that's already pretty good, that's a real asset.

"Tonight he just put the team on his back."

All that was left was the whipped cream pie, which, as usual, was delivered by right fielder Josh Reddick.

"This is a walk-off kind of team," Jaso said. "This was my first here, and I'm just so glad that it was whipped cream and not shaving cream (which stings the eyes). It was probably my biggest night in this uniform.

"I was glad to do it. We'd already gone 10 innings, and I didn't want to be squatting (behind the plate) any more tonight."

Jaso had never homered in the Coliseum until Friday, when he went deep to right-center. Then he did it again in the third inning against Roark, but for seven innings that was all the A's had to show for their night against Roark. They finally got him out of the game in the eighth, and once the A's were into the Nationals bullpen there was at least a sense of starting over.

Soriano came in as untouchable as any pitcher in the game this season, but in the ninth Jaso singled, Lowrie double for one run and Donaldson tied it with a single to right.

Lowrie might have been out if the throw had made it to the plate, but Soriano cut it off, after which catcher Wilson Ramos chastised him.

"It was going to be close; I know that," Lowrie said. "But we scored, which is all that counts."

The A's have three walk-off wins at the Coliseum this year and eight wins in their final at-bats or, as Jaso said, "we've been the walk-off team here the last couple of years."

  • Coco Crisp missed a third straight start Saturday with neck stiffness and there is no telling when the center fielder will return to the lineup. Manager Bob Melvin said he doubts Crisp will start Sunday and isn't sure if he'll even be back for the three-game series with the Chicago White Sox that begins Monday. "There's no timetable right now," Melvin said.

  • A's starter Sonny Gray allowed six hits in seven innings Saturday, but four of the hits, including a home run by Danny Espinosa and a two-run double by Kevin Frandsen, came consecutively in the third inning.

  • Left-handed reliever Eric O'Flaherty, originally scheduled to be back around the All-Star break, is on a path that would have him back in the A's bullpen sometime in June. He threw to hitters Saturday for the first time since his Tommy John surgery of last May 21 when he was with Atlanta. He threw only fastballs. "In the first live session they didn't want me to get too amped up," O'Flaherty said. "I felt comfortable out there."

  • The postgame fireworks were themed around the music of Journey, and Melvin said he could remember coming to a Day on the Green concert to see the rock group many moons ago. "I saw them here at Day on the Green and at Toso Pavilion," Melvin said.
