OAK@BOS: A's get another run on Reddick's double

NEW YORK -- Josh Reddick entered Friday's game in New York hitless in his first 27 at-bats at Yankee Stadium. But that's not the skid the A's are worried about at the moment.

Reddick hasn't been hitting in any ballpark this year, having compiled just one hit in his last 16 at-bats going into the series opener at Yankee Stadium. Overall, he'd been just 12-for-81 (.148) on the season before Friday, after batting .164 in the final month of the 2012 campaign.

"I think it could potentially be more mental, as far as carryover from last year," manager Bob Melvin said. "But he had a good spring. We saw the same swing that he had for the better part of last year. He's just gotten off to a little bit of a slow start, and sometimes the longer you go, the tougher it is to dig your way out."

Reddick got a hit in Wednesday's game and also walked three times, using a plate approach that lent some confidence in Melvin's belief that he'll soon turn things around.

"Hopefully it's a couple games like that that get him going in the right direction," Melvin said, "because certainly the ability is still there."

Nakajima begins rehab stint in Triple-A

OAK@CLE: Nakajima sustains hamstring strain injury

NEW YORK -- Hiro Nakajima was officially added to Triple-A Sacramento's roster on Friday to begin a rehab stint with the River Cats, and that's where he'll stay for an undetermined amount of time.

His first appearance with Oakland, it seems, will come later rather than sooner.

"It almost is a complete start-over for him, based on the time he's had off," manager Bob Melvin said. "He's going to get multiple at-bats. We want him to be comfortable. We want him to have some success before we bring him here."

Nakajima, signed to a two-year deal worth $6.5 million this offseason to become the team's shortstop, strained his hamstring during the final week of Spring Training, which led to a rehab process that has spilled over into a second month.

There was doubt, though, as to whether he would've made the roster even if healthy, following an unimpressive spring next to a productive one by Jed Lowrie, who has since claimed everyday shortstop duties and thrived, entering Friday batting .327.

Nakajima can be with Sacramento in a rehab capacity for 20 days before the A's have to decide whether he's ready to join the big league club or if they need to officially option him to the River Cats should he need more at-bats.

"In this type of atmosphere, he can relax a little more," Melvin said. "He can't help but try to do a little too much, playing in a new country with a new team, playing a different brand of baseball. There are a lot of expectations, and then he gets injured. It was just a rough Spring Training for him, but we feel like this is the right way to go about it for him, getting him the at-bats and getting him comfortable and confident, because he's definitely a much better player than the numbers that we saw him put up in Spring Training.

"For me, I like to get my guys 60-65 plate appearances in Spring Training. I don't know that it will take that long, but that's a normal Spring Training for me to get ready for a big league season."

Nakajima was scheduled to play seven innings at shortstop on Friday, and that's where he'll mostly play, though, "I'm not ruling out some second base," Melvin said.

Young likely headed to DL; Taylor to join A's in NY

OAK@BOS: Young smacks second homer of game in eighth

NEW YORK -- There was thought that a pain-free running session would make A's outfielder Chris Young available off the bench for Friday night's 2-0 win against the Yankees.

But Young, sidelined by a strained left quad, "didn't have his best day running," said manager Bob Melvin, and it now looks like he's headed for the disabled list, with a source telling MLB.com on Friday night that outfielder Michael Taylor is heading to New York in time for Saturday's game.

Taylor was pulled from Triple-A Sacramento's game in the second inning Friday so he could catch a red-eye flight. Young, who has been held out of the starting lineup for three straight games after getting injured in Monday's 19-inning win against the Angels, would have been a natural choice to start against Yankees lefty CC Sabathia. Instead, with Coco Crisp also out, Melvin started Yoenis Cespedes in center field and Seth Smith -- who entered hitting .435 against southpaws this season -- in left.

Crisp, like lefty Brett Anderson, remained in the Bay Area to continue his rehab process on a strained left hamstring.

Worth noting

• With Crisp resigned to the disabled list, Melvin had to do some juggling with his lineup on Friday and opted to give Adam Rosales his first career start in the leadoff spot.

The decision proved a good one, with Rosales sending the first pitch he saw from Sabathia over the left-field wall for his first home run of the season.

"Someone had to hit there," Melvin said before the game. "He's excited about it. We'll see where we go. That just shows you what we miss when Coco's not there. That's one of the no-brainers, as far as the lineup goes, when Coco is there, that he will lead off. At this point, we're just trying to mix and match on a particular day."

• Prior to his Friday start, right-hander A.J. Griffin was singing in three different languages -- English, Spanish and French -- while playing his guitar in the A's clubhouse, with Yoenis Cespedes sitting beside him.

"It looked like he was serenading Cespedes to me," said Melvin, laughing.

Griffin eventually passed the guitar onto catcher John Jaso, who showcased some impressive musical talent.
