LAS VEGAS >> Patrick Mahomes passed for 262 yards and two touchdowns and the two-time defending champion Kansas City Chiefs remained undefeated with a 27-20 victory over the reeling Las Vegas Raiders on Sunday.

The Chiefs (7-0) extended their winning streak to 13 games, including the playoffs. Their last loss was at home to Las Vegas, but the Chiefs are 5-0 against the Raiders at Allegiant Stadium and 6-0 there including the Super Bowl in February.

Las Vegas (2-6) has lost four consecutive games, but this was the first time the Raiders had scored at least 20 points since a 20-16 victory over Cleveland on Sept. 29.

Mahomes became the fastest quarterback in NFL history to reach 30,000 yards, doing it in his 103rd game. Matthew Stafford had hit that mark at 109 games.

Mahomes’ top target was Travis Kelce, who had 10 catches for 90 yards, both season highs.

Kelce also had a touchdown catch, his 75th to pass Jason Witten for fifth on the NFL tight end list. Kelce moved within two of breaking Tony Gonzalez’s team record.

Gardner Minshew completed 24 of 30 passes for 209 yards and two touchdowns for Las Vegas, but was sacked five times. Jakobi Meyers, who missed the two previous games because of an ankle injury, caught six passes for 52 yards and the TD.

Minshew had the burden of carrying an offense that had virtually no running game, finishing with 33 yards, averaging 1.6 per carry.

The Raiders, however, made the champs work for this victory. But Las Vegas failed to take advantage of key opportunities.

Las Vegas trailed 17-13 in the third quarter when safety Tre’von Moehrig intercepted Mahomes’ pass to give the Raiders the ball at the Chiefs 3. Running plays resulted in plays of 2 yards, a no gain and a loss of 2 before Minshew was sacked on fourth down.
