Emil Brown singled home the winning run in the 10th inning, and the Oakland Athletics beat the Baltimore Orioles 2-1 on Monday night.
With two outs, Daric Barton singled against Jim Johnson (0-1), and Frank Thomas followed with a walk to set up Brown's third hit of the game.
Joey Devine (3-0) pitched a scoreless 10th for the win, handing Baltimore its third consecutive defeat.
Ramon Hernandez tied the score in the ninth with a slow RBI groundout to shortstop. Melvin Mora doubled to start the inning and advanced to third on Kevin Millar's long flyout.
Oakland closer Huston Street blew his second save in 11 chances. He had converted his previous nine in a row.
Rajai Davis' bases-loaded infield single with two outs in the seventh gave the Athletics a 1-0 lead in a game dominated by the starting pitchers.
Dana Eveland gave up three hits in seven innings, matching the longest outing of his career. He walked four, struck out four and allowed one baserunner as far as second.
Orioles starter Garrett Olson was just as unhittable, giving up one run and four hits in 6 1-3 innings. He walked one and struck out seven.
After getting the first out of the seventh, Olson gave up a hit to Brown and walked Jack Cust. Matt Albers took over for Olson and got Bobby Crosby to fly out before pinch-hitter Jack Hannahan beat out an infield single against Jamie Walker to load the bases.
The speedy Davis hit a slow roller into the hole between first and second and easily beat Walker to the bag, allowing Brown to score.
Adam Jones and Jay Payton opened the eighth with singles. After Luis Hernandez sacrificed both runners against Andrew Brown, Alan Embree came on to retire Brian Roberts on a short fly to right field and Nick Markakis on an infield grounder.
The A's hit .234 against left-handed pitching in their previous 12 games against them. Olson, in his second start of the season, was as tough as any of those lefties.
Eveland was coming off his worst start of the season, when he gave up six runs in 5 1-3 innings in at the Los Angeles Angels last Wednesday. Against the Orioles he looked like the guy who opened the season allowing one run in his first 16 innings.
