Ka'aihue relishes new opportunity with A's

PHOENIX -- It's not exactly the most ideal situation, entering a first-base competition that includes three other players, but the A's Kila Ka'aihue wouldn't have it any other way right now.

Following a frustrating season in Kansas City, where he spent the first 10 years of his professional career, Ka'aihue enters camp with the A's feeling refreshed and "like I have control over my career." That wasn't necessarily the case when he was wearing a Royals uniform.

"Being here, it's a similar situation, where I have the opportunity to make the team," he said. "But, at the same time, if I don't, it won't be because they always had someone else in mind. I'm not having to look over my shoulder anymore. In Kansas City, they always had someone else they wanted. They never really wanted me there. I always did well enough to hang around but was always passed up."

Ka'aihue likened his role with the Royals to a bandage. He began the 2011 season as the club's regular first baseman but was quickly replaced by Eric Hosmer, whose arrival had long been anticipated, after just 23 games. At the time, Ka'aihue was hitting just .195 with two home runs and six RBIs. At designated hitter, where he could see time with the A's this spring, he was blocked by Billy Butler in Kansas City.

Ka'aihue ultimately spent the majority of the season in Triple-A and, in September, was designated for assignment before being traded to Oakland.

"I wouldn't say it was my toughest year, but I would say it was the least enjoyable," he said. "In 2006, I had a knee injury and struggled badly at Double-A. That was frustrating because I was hurt. Last year was flat-out not enjoyable. I did better, but it wasn't fun. It was just a hard year."

Ka'aihue couldn't be happier with the A's, a team that's much closer to his hometown of Honolulu. His brother, Kala, spent some time in the organization in 2010 and promised he'd "love it."

"Everything he's said has been right so far," he said. "The people here are awesome. It just has a different feeling here to it. It doesn't feel like you're on the outside, looking in on a bunch of older guys. This team, there's a bunch of younger guys, and it's refreshing. I feel refreshed. I feel like I want to be here."

The A's have long been enamored with Ka'aihue's power potential, after he shot to prominence in 2008 when he combined for 37 home runs and 100 RBIs with a .314 average for Double-A Northwest Arkansas and Triple-A Omaha. But he also wants to make them aware of his defensive skills, which, if proven to be above average, could further shake up the first-base competition with Daric Barton, Brandon Allen and Chris Carter.

"I'd say that's the best part of my game," he said.

Such confidence wasn't always there. It wasn't until the Royals put him on waivers and the A's reeled him in that he found motivation. Ka'aihue also gained plenty perspective when he learned his wife, Blair, was pregnant with twin boys, due on the Fourth of July.

"I feel like if I win a job, I might have a chance to stay here for a while," he said. "It's a good feeling, after having been passed up over and over. I love the guys in Kansas City, but I'm looking forward to this year so much more. And I can't wait to play them."

A's await injured Sizemore's prognosis

PHOENIX -- The wait continues for news on third baseman Scott Sizemore's left knee injury.

The MRI exam that was expected to take place Sunday won't happen until Monday morning, when Sizemore is scheduled to see a specialist.

"It's just tough to find a place where you know you're going to find a good image [on the weekend]," manager Bob Melvin said.

Sizemore was on crutches in the A's clubhouse on Sunday afternoon but, understandably, said he'd prefer not to comment on the situation until he knows more.

Having spoken to Sizemore Saturday night, Melvin said in the morning, "He's a little down, but we're holding out hope for good news. If ever there was a time to have that happen, it's early in camp so there's time to recover."

Melvin is calling the injury a sprain, but those nearby when Sizemore went down Saturday afternoon said they heard a popping sound. Depending on the severity of the injury, the A's could be forced to try several hands at third base during the next few weeks.

Among the candidates to fill in for Sizemore are Josh Donaldson, Eric Sogard and Adam Rosales.

Worth noting

• Melvin again raved about lefty Brian Fuentes, who had a mild hamstring issue for a couple days but was back on the mound facing hitters Sunday.
