ANAHEIM -- Torii Hunter couldn't help it.

After the Angels' crushing 6-5 loss to the A's on Sunday, the right fielder admitted Monday that he had a hard time getting a good night's sleep.

"I kept waking up all of Sunday night," Hunter said. "It was a tough one all around. You really can't explain it.

"I just feel bad. This late in the season, we need these games. It doesn't settle well. It doesn't settle well with any of the players in here. I'm still feeling it."

Yet, manager Mike Scioscia said no pep talk for his players was necessary before Monday's series opener against the rival Rangers, believing his team was ready to play.

"These guys are good at turning the page. Hopefully we are going to execute and get a win," Scioscia said. "As losses go, that was tough, but our guys have a lot of energy and will be ready to go."

Going into Monday's contest, the team sat three games behind the Red Sox and two games back of the Rays in American League Wild Card race with only three left to play.

"Hopefully we'll play at the level of our capabilities," Scioscia said. "With the position we are in, it is a crucial we win and get some help."

For bullpen, a season of upheaval

ANAHEIM -- In an up-and-down year for the Angels bullpen, Sunday against the A's had to take the cake.

With closer Jordan Walden surrendering four runs in the top of the ninth inning and the Angels eventually losing, 6-5, manager Mike Scioscia understands that much of the hardships are based on depth.

The struggles of Michael Kohn, Fernando Rodney and Kevin Jepsen throughout the season threw Walden and a slew of other pitchers into unexpected roles.

"Some saves have got away and leads haven't been held, and I think some of it has to be with the depth, Scioscia said.

"We have maximized the depth we've had in the bullpen and, for the most part, they held leads. Though, some have got away."

Another reason for the instability: youth.

With Bobby Cassevah at age 25, Trevor Bell at 24 and Walden at 23, "we knew when making the switches that some games would be lost to youth, but that's helped to maximize our depth," said Scioscia.
