OAKLAND, Calif. -- Having discovered his power stroke at the Oakland Coliseum, Athletics catcher John Jaso was more impressed by the ball he hit that didnt leave the park than he was by his second home run in as many days. That might be because it came in the 10th inning and gave Oakland its third walk-off win of the season. Jaso doubled in pinch-runner Nick Punto with two outs in the 10th inning to lift the As to a 4-3 win over the Washington Nationals on Saturday night. Jaso, who had not hit a home run in Oakland until his solo shot in Fridays 8-0 win, also homered in the third before delivering the fourth game-ending hit of his career. "Its funny because I thought that last ball I hit I hit harder than the other two and it hung up for some reason," Jaso said. "I dont know if the wind shifted, but I thought I hit it harder than the other two." After being limited to two hits over the first eight innings, the As scored twice in the ninth off Nationals closer Rafael Soriano to force extras and storm back for their third walk-off win this season. 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. "Sometimes certain guys come up key in games when you dont get many hits," Oakland manager Bob Melvin said. "(Jaso) did most of the damage. When you get down to those situations, it just becomes a grind." The Nationals were three outs from winning and had their rock-solid closer on the mound before Oakland greeted Soriano with three consecutive hits to open the ninth. Jaso singled and scored on Jed Lowries double. Josh Donaldson followed with a line drive single to drive in Jaso with the tying run. "Going into the ninth with a two-run lead and a guy that hasnt given up a run in 25 innings and it doesnt happen for you, its disappointing," Washington manager Matt Williams said. "Thats baseball." It was Sorianos first blown save since Aug. 17, 2013, and ended his career-high streak of 25 consecutive scoreless innings. That spoiled a stellar outing by Washington starter Tanner Roark. Coming off the worst start of his season, Roark was masterful while shutting down the As offence. He allowed two hits over 7 2-3 innings, struck out five and didnt walk a batter. He gave up Jasos two-out home run in the third before retiring the next 13. The Nationals backed him with just enough offence until the bullpen broke down. Danny Espinosa hit a towering home run off Oakland starter Sonny Gray with one out in the third to give the Nats an early lead. Zach Walters and Denard Span followed with singles before Kevin Frandsen lined a two-run double to the gap in left-centre to make it 3-0. Jasos two-out home run off Roark in the bottom of the third trimmed Washingtons lead to 3-1. "Its strange how a pitcher can get on a roll like (Roark) did and everything we put in play was caught," Jaso said. "Those kind of days, thats when you want to get into the bullpen and change the momentum." Roark left with two outs in the eighth after a throwing error by Espinosa allowed Reddick to take third. Roark fielded Eric Sogards grounder cleanly, but his throw to first hit Reddick in the back of the helmet and ricocheted near the Nationals dugout. Tyler Clippard replaced Roark and retired pinch-hitter Derek Norris before the As rallied for the tying runs off Soriano. Sean Doolittle (1-2) pitched one inning for the win to help Oakland overcome an uneven outing by Gray. Gray, the AL pitcher of the month in April, struck out three and walked two.

CHICAGO -- Everything was going just fine for the Oakland Athletics. And then? "The circus came to town," Josh Donaldson said. Thats one way to look at it. Avisail Garcia drove in two runs with a bases-loaded single in the eighth inning, and the Chicago White Sox beat the struggling Athletics 2-1 on Wednesday night. Oakland was in line for the win after Jeff Samardzija threw seven scoreless innings, and Adam Dunn singled in a run against his former team. Instead, the As lost for the 10th time in 13 games because the bullpen failed again to protect a lead. Luke Gregerson (4-4) came on in the eighth, and things quickly fell apart. It was the third time in four games that the Athletics relievers blew a lead. Gregerson gave up a leadoff single to Carlos Sanchez, and first baseman Nate Freiman threw wildly trying to force pinch-runner Leury Garcia at second after fielding Adam Eatons grounder. The runners moved to second and third with one out when Gregerson bounced an 0-2 pitch to Jose Abreu before striking him out. He intentionally walked Conor Gillaspie to load the bases, and Garcia lined a pitch up the middle for a two-run single that made it 2-1. The late rally made a winner of Zach Putnam (5-3), who pitched a scoreless inning. Jake Petricka worked the ninth for his 12th save in 15 chances. "It does a lot for us," Eaton said. "It really does. We want to show were not dead. The White Sox are here to stay. We want to be better next year, and were going to continue to push to be better. It starts with this month." Samardzija looked sharp in his first start in Chicago since the Cubs traded him to Oakland on July 5. He gave up six hits, struck out six and walked two. "They made me battle out there, a leadoff walk, a couple of leadoff hits," Samardzija said. "So I was really grinding out there." White Sox rookie Chris Bassitt was almost as good. In his second major league start, thhe right-hander gave up one run and five hits.dddddddddddd He left to loud cheers after Derek Norris led off the seventh with a broken-bat single. Dunn, recently acquired from the White Sox, gave Oakland a 1-0 lead with two out in the fourth when he drove in Coco Crisp with a single past a diving Gillaspie at third. It looked as though that would be enough before the game turned in the eighth.
