ANAHEIM, Calif. -- Jordan Walden literally had the game in his grasp in the ninth inning.
Then it all came apart for the rookie closer and the Angels in a devastating defeat that left Los Angeles on the brink of elimination.
Walden wasted a three-run lead in the ninth inning, throwing away a potential game-ending, double-play grounder Sunday in a 6-5 loss to the Oakland Athletics.
Los Angeles dropped three games behind Boston and two back of Tampa Bay in the AL wild-card race with three games left.
"It hurts to lose a game like that," Angels right fielder Torii Hunter said. "We got insurance runs in the bottom of the eighth and just couldn't close it out. There were some mistakes there, and they capitalized on them. When you've got a chance to get that wild card, you just can't make mistakes -- defensively for sure. So this game really hurts, trust me. We've got an uphill battle. But at the same time, we've still got life left and we're still breathing."
Trying to get a four-out save, Walden gave up Josh Willingham's 28th homer leading off the ninth.
"I knew I was working with Aybar," Walden said. "But the ball was hit back to me so hard and so quick, I hesitated for a second and the ball just sailed on me."
"I blew one by Suzuki and then threw another one that was better, but he just stuck his bat out there and it went down the line," Walden said. "I let the team down. We battled all day, and I lost the game for us. It's tough. I'm really disappointed in myself. I feel like if I take it home with me, I might stay awake until 6 in the morning and not get any sleep."
"We were down three runs and we battled back," Willingham said. "They gave us a couple of things, and we took advantage of it. We had a couple of great at-bats, like Kurt Suzuki on that ball to right field in a key situation, and then that ground ball up the middle that could have ended the game gave us a chance."
Joel Pineiro made his final start of the season for the Angels on his 33rd birthday, allowing three hits over 6 1-3 scoreless innings and retiring his first 13 batters. He took a one-hitter and a 3-0 lead into the seventh, then watched the collapse on television in the clubhouse.
Oakland's Rich Harden allowed three runs and eight hits in six innings and finished his season with a 5.12 ERA.
Jemile Weeks' RBI single and Crisp's first sacrifice fly cut the gap to 3-2 in the eighth -- the latter driving in the first run against Downs at home in 28 appearances this season.
"You can never count anybody out until the last out is made," Pineiro said. "No lead is safe at any time. This one hurts a lot. We've got our work cut out for us the next three days."
