Contending Athletics defeat Mariners in 10

OAKLAND, Calif. (AP) - Seattle Mariners manager Eric Wedge has embraced the opportunity for his club to impact the AL West and wild card races, relishing each game in a playoff-type atmosphere.

He'd only be happier if his Mariners made a more positive mark.

Brandon Moss hit a three-run homer in the 10th inning after Josh Donaldson's tying two-run shot in the ninth, and the Oakland Athletics gained ground on the first-place Texas Rangers with a stunning 7-4 win over the Mariners on Saturday.

"Those guys are feeling it over there," Wedge said. "The fans are feeling it. Obviously the players are feeling it. You can sense the excitement in the air, and it's great for our guys to be playing in that environment. You have to finish games off. We just weren't able to do that today."

Few teams have in extra innings in Oakland this season.

Coco Crisp singled off Oliver Perez (1-3) leading off the final inning for his fourth hit. Stephen Pryor entered with one out and walked Yoenis Cespedes on four pitches."

Moss hammered the first pitch against Pryor well over the wall in right for his 21st home run, sending Oakland (90-68) streaming out of the dugout to celebrate its major-league leading 14th walk-off win.

"What hurts us is that leadoff walk," Wedge said. "Now you bring the tying run into the game and then he hung a breaking ball. His stuff's good. That's the type of closer that we want and he's going to be. It just didn't work out for us today."
