OAKLAND, Calif. -- Dressed in a full-length bright yellow A's bathrobe, Josh Reddick snuck up on Brandon Hicks and planted a whipped cream pie in his teammate's face right there at his locker.

"How dare you avoid me!" Reddick screamed.

"I sure wasn't expecting that one," Hicks said, grinning.

He should have been after he led off the bottom of the ninth with a towering home run to center for his first major league clout, lifting the Oakland Athletics to a 4-3 victory over the Texas Rangers on Wednesday.

Hicks connected off Michael Kirkman (0-1) for Oakland's majors-leading ninth walkoff win. He became the fourth player in franchise history to hit a game-ending homer for his first career longball and the second this year -- joining Derek Norris, who did it June 24 against San Francisco.

"It's exciting to get that big hit in that situation," Hicks said. "That's awesome. I've been waiting a little while."

Reddick hit a tying two-run double with two outs in the seventh to help the A's salvage a two-game split with the AL West-leading Rangers.

Evan Scribner and Sean Doolittle each pitched a perfect inning, and All-Star Ryan Cook (3-2) worked the ninth for the win. Cook hasn't allowed a run in his last nine outings.

Then Hicks drove a 1-1 pitch high over the center-field wall and rounded the bases to a home-plate celebration that's becoming commonplace at the Coliseum.

"What a homer!" pitcher Jarrod Parker hollered through the clubhouse.

Michael Young hit a go-ahead RBI single in the sixth but the Rangers couldn't hold it.

Craig Gentry hit an RBI double and Nelson Cruz added a run-scoring single for Texas, which now heads into a key weekend road series against the second-place Angels.

The A's, meanwhile, host the New York Yankees in a four-game series having won 10 of 12 -- with a remarkable four walkoff wins in their last seven home games after getting three total all of last year.

"The way we're playing, if we'd lost both of these games it would have been demoralizing," manager Bob Melvin said.

Josh Hamilton went 1 for 4 and kept his average right at .300 for the second straight day. He hasn't fallen below that mark this year.

Starter Colby Lewis lasted five innings in his comeback from the disabled list, allowing three hits and one run on 75 pitches. He struck out three and walked two.

After Gentry's double put Texas ahead in the top of the fifth, Brandon Inge homered leading off the bottom half to tie it.

In the sixth, Inge stumbled after fielding Adrian Beltre's grounder and missed a chance for an out. Young singled moments later as Texas took the lead.

Texas is headed into a stretch with seven of its next 13 games with the Angels. The Rangers open a three-game series at Anaheim on Friday following an off day Thursday.

"Yes, it's a significant series, significant in that they can either catch up or we can move ahead," manager Ron Washington said.

Lewis came off the DL to pitch for the first time since allowing season highs of 12 hits and eight runs June 23 against Colorado. It marked his first DL stint since rejoining the Rangers in 2010, and the right-hander had been out since June 24 with tendinitis in his right forearm.

The A's loaded the bases against Lewis in the fourth and pitching coach Mike Maddux made a mound visit following a two-out walk to Brandon Moss. Then Lewis escaped the jam when he got Norris on an infield popup.

Yoenis Cespedes, back in left field after nursing a sprained left thumb, singled but missed a shot at a fifth straight multihit game.

Coco Crisp returned to Oakland's lineup, playing center field after missing three games with a sore left shoulder he aggravated on Friday night at Minnesota. He beat out an infield single to start the bottom of the first, then drew a walk and stole second and third in the fifth for his 17th and 18th steals. It was his fourth multi-steal game this season and 28th of his career.

A's starter Travis Blackley gave up three runs on six hits in 5 1/3 innings and pitched well considering his long layoff. He worked out of the bullpen July 7 against Seattle before the All-Star break, but this was his first start since beating the Rangers on July 1 at Texas with seven strong innings.

And he was thrilled with how things turned out.

"Everyone calls us scrappy," Blackley said. "Don't sleep on us. All 27 outs, we're going to keep coming."

Inge was 0 for his last 11 and mired in an 8-for-63 funk spanning 17 games before connecting for his eighth home run to snap a 27-game homerless streak.

"You have to give them credit for constantly fighting and then pulling it off," Washington said.
