OAKLAND -- The Raiders' hopes of reaching the halfway point of the season with a .500 record were buried under the rubble of big plays in a 42-32 loss to the Tampa Bay Buccaneers at O.co Coliseum on Sunday.

Rookie running back Doug Martin rushed for 251 yards on 25 carries and had touchdown runs of 45, 67, 70 and 1 yards as the Bucs amassed 515 yards of total offense.

Most galling to the Raiders, the Bucs got 437 of those yards and four touchdowns on 17 offensive plays of 10 yards or more.

"We talked all week about big plays and trying to prevent 'em," Raiders defensive end Dave Tollefson said. "You look at all those backbreaking scores ... we've just got to get some stuff cleaned up."

Instead of a three-game winning streak and a .500 record, the Raiders take a 3-5 record into the second half of the season, a game behind the second-place San Diego Chargers (4-4) and two games behind the Denver Broncos (5-3) in the AFC West.

Tampa Bay (4-4) had to work for it in the fourth quarter as the Raiders overcame a 35-17 deficit after Martin's 70-yard run to close within 35-32 on Carson Palmer's fourth touchdown pass of the game, a 13-yarder to Marcel Reece with 3:51 left.

With Darren McFadden out since the second quarter with an ankle injury of undetermined severity (X-rays were negative) and a big deficit, Palmer completed 39 of 61 passes for 414 yards.

The pass to Reece came after a 25-yard touchdown pass to Rod Streater and scores of 4 yards and 1 yard to tight end Brandon Myers, and the final scoring drive came on patient throws underneath.

After the Raiders came up with a defensive stand and a three-and-out, Palmer and the Raiders got the ball back with 2:42 to play and two timeouts -- plenty of time to get in position for a touchdown or game-tying field goal.

Instead, Palmer threw incomplete down the left sideline to Streater on first down, then tried it again on the very next pass to Denarius Moore, throwing a floater off his back foot that was intercepted by Ahmad Black.

Black returned it 34 yards to the Oakland 22, and three carries later, Martin had his fourth touchdown of the day, this one from a yard out.

The Bucs led 42-32 with 1:49 left, and all that was left was for Palmer to throw his third interception of the game, this one by E.J. Biggers.

Palmer and Raiders coach Dennis Allen were fine with the decision to take shots downfield, although there were problems with the execution.

Allen did take exception with the Raiders' ability to tackle, particularly against Martin, who had the biggest rushing game against Oakland since Seattle's Shawn Alexander gained 266 yards on 35 carries in the rain at Husky Stadium in 2001.

Martin, a Northern Californian native, had 221 yards on 17 carries in the second half, which began with the Raiders leading 10-7 after Palmer's touchdown pass to Streater with 1:20 left before intermission.

"We had an opportunity to make a few big plays and missed some tackles, and when you miss tackles on that guy (Martin), he takes them for big gains," Allen said.

Tampa Bay quarterback Josh Freeman completed 18 of 30 passes for 247 yards and touchdown passes of 25 yards to Vincent Jackson and 4 yards to Mike Williams.

"Doug comes out, explodes, Vincent made some explosive plays, Mike Williams made some explosive plays," Freeman said. "Guys are taking a lot of pride in their work and coming out and executing on Sundays."

Both of the scores, as well as a 64-yard pass to Jackson that preceded his touchdown, came against cornerback Michael Huff. Coming off three solid game, Huff made no excuses.

The long pass came on a third-and-15 when Huff bit on an in-fake by Jackson, only to see the wide receiver fly past him and into the clear.

"I should have stayed deep," Huff, the converted safety, said. "I should have trusted the coverage."

Strong safety Tyvon Branch, who led the Raiders with 11 tackles, said, "That wasn't our brand of football. That's not the way we've been executing the past few weeks. We've got to go watch the film, look ourselves in the mirror, come back in and fix it."
