Left fielder Josh Willingham and first baseman Brandon Allen both could factor heavily into the A's fortunes next season.

One continued raking Monday night and the other continued struggling, and both were noteworthy developments in the A's 6-3 victory over the visiting Los Angeles Angels.

Willingham drove in four runs, mashing a three-run homer in the first inning that got Oakland started on the right foot.

Allen went 0 for 3 (with a walk) and is mired in a 0 for 21 slump, the longest hitless streak of his still-brief major league career.

A's manager Bob Melvin will welcome all the offense he can get from Willingham, who is capping quite the impressive season as he prepares to enter free agency for the first time this winter.

Willingham's 25 homers are one off his career high set in 2006 with the Florida Marlins. At 88 RBIs, he's one shy of his career best from 2007. With 15 games to go, he has a legitimate chance to post the A's first 100-RBI season since Frank Thomas knocked in 114 in 2006.

Willingham entered Monday tied for fifth in the American League in homers since the All-Star break (13), but he shrugged off the strong finish he's enjoying.

"I feel good," Willingham said. "We signed up for 162 of them, so you've gotta play them all."
