KANSAS CITY, Mo. (AP) -- The Chiefs finally clinched their third consecutive AFC West title and the No. 1 seed in the playoffs, and Patrick Mahomes and the rest of Kansas City's offense continued to shatter records in a 35-3 whitewash of the rebuilding Oakland Raiders on Sunday.
Mahomes threw for 281 yards, highlighted by a 67-yard TD pass to Tyreek Hill and an 89-yard TD toss to Demarcus Robinson. That gave the first-year starter 5,097 yards and 50 touchdown passes, joining Peyton Manning as the only QBs to hit 5,000 and 50 in the same season.
Manning had 5,477 yards and a record 55 TD passes for the Broncos in 2013.
Hill finished with five catches for 101 yards, becoming the Chiefs' single-season leader for yards receiving with 1,479, while adding a fourth-quarter touchdown run. Damien Williams added 51 yards and a score on the ground as the Chiefs (12-4) beat the Raiders for the eighth time in nine games.
The decisive win came after Kansas City squandered a chance to clinch the division with a fourth-quarter collapse against the Chargers and again in a shootout loss last weekend in Seattle.
Derek Carr had his league-leading streak of 332 passes without an interception snapped when the Chiefs' Daniel Sorensen returned a pick for a touchdown in the first quarter. Carr threw another pick and lost a fumble as Oakland (4-12) turned the ball over on its first four possessions.
He finished 23 of 32 for 184 yards, while Doug Martin ran for 100 yards but also lost a fumble.
The Chiefs eliminated any postseason drama in the first 20 minutes.
Mahomes started the scoring barrage when he threw a perfect post pass to Hill, who waltzed into the end zone for his long touchdown reception. And a few minutes later, Sorensen stepped in front of tight end Jared Cook — who had inexplicably stopped his route — for a 54-yard pick-6.
The Chiefs defense kept causing turnovers, and Williams capped another effortless drive with a short touchdown run to give Kansas City a 21-0 lead late in the first half.
The league's highest-scoring offense continued its onslaught after the break.
Mahomes delivered the dagger when he floated a pass deep downfield to Robinson, who ran out of the grasp of his would-be tackler. Robinson was so far ahead of the defense that he turned around at the 15-yard line and backpedaled into the end zone — getting a taunting call as his reward.
Not that it mattered for the Chiefs, who were already celebrating their postseason bye and what they hope is a Super Bowl road through Arrowhead Stadium. Hill merely added to the party when he added his rushing touchdown in the fourth quarter to put the game away.
