ANAHEIM -- A's outfielder Rajai Davis made quite a splash in his Oakland debut last Thursday, going 3-for-4 with a triple in a blowout win the day after being claimed off waivers from the Giants.

He made another splash Monday night in another blowout win. After entering the game as a pinch-runner in the seventh inning, the fleet-footed 27-year-old stole second base and scored on a single by Ryan Sweeney, then capped what snowballed into an eight-run inning with a two-run single as the A's rolled to a 14-2 victory in the opener of a four-game series at Angel Stadium.

Given a fresh start after opening the season in a 1-for-18 slump before the Giants cut him loose, Davis -- who got his third start with Oakland on Tuesday -- is thoroughly enjoying the change of scenery.

"I'm just in a good place," he said before batting practice. "My body feels great, and I have a great opportunity here."

He's particularly digging the famously loose atmosphere in the A's clubhouse, where seriousness typically takes a back seat to frivolity until it's time to hit the field.

"It is a relaxed environment," Davis said, "and that allows players to go out and do what they do best. Some places, there's pressure, but it doesn't feel like that here. It seems like guys are just happy and motivated."

Davis is one of the more subdued members of this fairly boisterous A's team; manager Bob Geren called him a "very quiet guy." But when asked if he liked wearing Oakland's white shoes, Davis perked up.

"I used to wear white shoes in high school," he said with a big smile. "They make you look faster."

Looking fast has never been a problem for Davis. The man could fly in flip-flops, and he entered Tuesday's game 5-for-5 in swiping bags. According to Geren, running isn't the only thing Davis does quickly

"When I want to put him in the game, he's already all stretched out and ready to go," explained the skipper. "He anticipates the situation."

Much of Davis' playing time will come as a pinch-runner and late-game defensive replacement, but not when the A's face a left-handed starter. On those days, Geren said, Davis will be his starting center fielder.
