A week ago, Mets top prospect Ike Davis was running on fumes.

Following a 114-game Minor League season split between two levels, he spent nearly a month playing for gold medal-winning Team USA at the IBAF World Cup.

"I feel pretty decent right now," Davis said Tuesday following his Arizona Fall League debut with the Surprise Rafters. "I feel pretty much even keel."

His bat said otherwise.

Davis exploded for a grand slam, two doubles and six RBIs on a four-hit afternoon, powering the Surprise Rafters to a 17-4 rout of the Peoria Javelinas.

Was it the few precious days of rest Davis enjoyed before suiting up in the desert? Perhaps. Or maybe it was just another example of the seemingly unlimited potential that the former first-round pick exhibits every time he swings the bat.

"It was a blast," Davis said of his AFL debut. "We have all these different teammates, different jerseys. It felt like kind of an All Star Game."

Davis certainly played like an All-Star. The 22-year-old first baseman scored twice and joined Yankees prospect Brandon Laird as the only players with four-hit debuts. Major League veteran Ian Kennedy (Yankees), who is coming back from an aneurysm in his pitching arm, allowed a run on two hits over four innings to pick up the win.

"It was a good first game," Davis said, adding that picking up the season-opening victory helped settle any pregame jitters he and his teammates may have had.

Judging from Davis' recent numbers, however, his nerves are a non-factor.

Selected by the Mets with the 18th overall pick in the 2008 Draft, he overcame a slow start this season to enjoy a breakout second half. After batting .288 in 59 Florida State League games, Davis found his stroke at Double-A Binghamton, where he improved his average (up to .309), slugging percentage (from .486 to .565) and OPS (from .862 to .951).

With Team USA, Davis continued to enjoy success at the plate, hitting .333 with three homers and five RBIs in 10 games.

"I'm basically just continuing to do what I did during the second half of the season," he said. "I found an approach that is working right now and am squaring up on the ball."

Laird also drove in three runs and scored twice, while fellow Yankees prospect Colin Curtis went 3-for-6 with two RBIs and a run scored for the Rafters.

Dodgers Minor Leaguer Lucas May hit a solo homer and Tigers farmhand Casper Wells contributed two hits and an RBI for the Javelinas. Sergio Santos (White Sox) scattered three hits over two innings of scoreless relief.
