DET@OAK: Reddick receives his Gold Glove Award

OAKLAND -- Josh Reddick was presented with his 2012 Rawlings Gold Glove Award before Friday's matchup against the defending American League champion Detroit Tigers, and the A's outfielder celebrated by returning to the starting lineup.

Reddick, who missed the past three games with a sprained right wrist, was greeted with a video compilation of some of his catches and a standing ovation.

"At the time of the injury. I didn't think he'd be back this soon," A's manager Bob Melvin said of his assessment following Reddick's collision with the wall in foul territory attempting a sliding catch in Houston on Sunday. "He could have played yesterday, but we wanted to be cautious and give him one more day."

Reddick became the eighth Athletics player to win a Gold Glove, and the fourth outfielder. He ranked third among American League outfielders with 15 assists.

"About halfway through last season, people started talking about his defense, and that carried over and over," Melvin said. "It's an award he takes pride in. Winning a Gold Glove on top of his offense shows he's an all-around player. He's accurate, charges the ball and has a good throwing arm."

The A's are also glad he's back in the lineup simply because of his leadership and ability to hit Tigers pitching. He entered the series opener 15-for-41 (.366) with two home runs and eight RBIs in 11 games against Detroit.

Cespedes, Crisp injured before A's walk off

DET@OAK: Cespedes nabbed at second base in eighth

OAKLAND -- Outfielders Yoenis Cespedes and Coco Crisp were injured during Friday night's opener with the Detroit Tigers, forcing the A's to finish their dramatic 4-3 walk-off victory in 12 innings without a designated hitter.

Manager Bob Melvin wasn't sure when Crisp was injured, only saying he tweaked his left groin "somewhere along the way."

Cespedes hurt his hand while being thrown out at second base on a steal attempt that ended the eighth inning. After receiving some attention from the medical staff, he stayed in the game and moved to center field when Crisp left the game in the top of the 11th, but he was unable to swing the bat, so Derek Norris pinch-hit for him in the bottom of the inning.

"X-rays were negative," Melvin said. "We'll see how he is tomorrow."

With no more position players available, Melvin spoke to home-plate umpire Paul Nauert to clarify his options. Chris Young, who hit for Seth Smith at the DH spot in the seventh, trotted out to center while relief pitcher Jerry Blevins, who recorded five outs, took over in the cleanup spot originally occupied by Cespedes.

"If someone was on base, I could bunt him over, otherwise I'd try not to embarrass myself," Blevins said.

Luckily no pitcher had to worry about stepping in the batter's box. Chris Resop, who relieved Blevins with two outs in the 12th, was four batters back when Josh Donaldson's walk-off homer ended the game.

Rosales is '90 percent' recovered

OAK@SF: Rosales' two-run homer extends the A's lead

OAKLAND -- Oakland infielder Adam Rosales stayed behind to rehab from a strained muscle (intercostal) on the left side of his torso while the A's went on their first road trip of the season.

He used the time wisely.

"I'm confident I am on the right path and healing quickly," said Rosales, who can play any infield position. "I'd say 90 percent. I'm almost there. I can swing it 100 percent, but that's not against live pitching. I've made a lot of progress the last week."

A's head trainer Nick Paparesta said he needed to see Rosales take grounders and batting practice before making any kind of judgment to send him on a rehab assignment.

"He will take batting practice sometime this homestand," Paparesta said. "So far he's had no problems."

Infielder Hiro Nakajima also spent the week getting back into playing shape after a pulled hamstring put him on the disabled list to start the season.

"He's been taking ground balls and he'll hit," Paparesta said. "When I see him run I can give you a better indication of where he stands."

Teammates feel for injured Sizemore

OAK@LAA: Sizemore injures knee, leaves game in fourth

OAKLAND -- A's infielder Scott Sizemore will undergo surgery on Tuesday in Florida and will miss his second consecutive season with a torn ligament (ACL) in his left knee.

"My stomach dropped when I saw him walk off the field," teammate Adam Rosales said. "It's the same knee. My heart goes out to him."

Sizemore is scheduled to fly to Pensacola on Sunday, confer with Dr. James Andrews on Monday and undergo surgery on Tuesday.

"Size is strong and a competitor," Rosales said. "He'll do his best to go through what he did last year. Nobody wants to experience that."

Former A's catcher Landon Powell also sustained the same injury twice in a short span.

"It doesn't happen a lot, but we do have some history with it," A's head trainer Nick Paparesta said.
