OAKLAND, Calif. -- It's been more than three decades since a quarterback played a game as poorly as Jake Delhomme did and still ended up on the winning side.

That's what facing a team as bad as the Oakland Raiders will do.

Delhomme threw a touchdown pass on the opening drive but completed only six other passes while throwing four interceptions in the Carolina Panthers' 17-6 victory over the Raiders on Sunday.

"I'm so glad we won, because you want to talk about a long plane ride home? We just didn't get this team going," Delhomme said. "It wasn't a good day offensively, but you know you're going to have those days, and the great thing about it is we won."

Delhomme, who had thrown only five interceptions in the first eight games for Carolina (7-2), finished 7-for-27 for 72 yards. The 26 percent completion rate was the worst in any of Delhomme's 74 starts and he threw four interceptions for just the third time in his career.

He became just the second quarterback since the merger in 1970 to complete fewer than 30 percent of his passes and throw four interceptions in a victory, according to STATS LLC. Cincinnati's Ken Anderson went 4-for-19 with four interceptions in a 14-10 victory over the Raiders on Oct. 19, 1975.

But against a Raiders team that hasn't scored a touchdown in nine quarters, that was more than enough to keep Carolina in first place in the NFC South.

Delhomme has been a big part of Carolina's success this season, throwing a go-ahead 65-yard TD pass to Steve Smith that helped the Panthers win their previous game, 27-23 over Arizona before their bye week.

"Jake knows he didn't have a good day," said defensive end Julius Peppers, who had three sacks. "He's a veteran. We all have bad games. We thanked him last [game] for bailing us out against Arizona. We couldn't stop nobody last [game], and they bailed us out."

DeAngelo Williams ran for 140 yards and scored on a 69-yard run for the only touchdown after the opening drive for Carolina. John Kasay added a 32-yard field goal in the fourth quarter after a 55-yard punt return by Mark Jones.

Andrew Walter, playing in place of an injured JaMarcus Russell, threw two interceptions before leaving temporarily with an ankle injury in the fourth quarter. Marques Tuiasosopo couldn't do much better in his first appearance in more than two years as Oakland (2-7) lost for the fourth time in five games under interim coach Tom Cable.

Oakland has just nine touchdowns on the season and none in its past 135:36 of game action.

"We couldn't catch a break," said Walter, who went 14-for-32 for 143 yards. "It was tough as an offense. We couldn't get into a rhythm all day. But I thought penalties put us in long down and distances."
