The Kansas City Chiefs won in dominant fashion on Sunday afternoon, defeating the rival Oakland Raiders at Arrowhead Stadium.

Here are 10 interesting notes about the victory.

1. The Chiefs continued their dominance over the AFC West.

The win helped Kansas City move to 25-3 against AFC West opponents since 2015, which are the most victories for any team against their own division in that span. Additionally, since Head Coach Andy Reid arrived in 2013, the Chiefs are 12-2 vs. Oakland and undefeated at Arrowhead Stadium.

Remarkably, Kansas City hasn't lost a Sunday divisional game since Week 13 of the 2014 season.

2. Kansas City didn't have a single penalty on Sunday.

The old adage of not beating one's self in big games couldn't have been executed better on Sunday as the Chiefs didn't commit a single penalty. Kansas City was penalized once during the game, but it was offset by a Raiders' foul and therefore didn't count in the box score.

That simply doesn't happen very often, as Sports Radio 810's Kurtis Seaboldt pointed out.

3. Tyrann Mathieu tallied another interception.

The Honey Badger picked off Raiders' quarterback Derek Carr on Oakland's first possession, leaping in air to notch his third interception of the year – Mathieu's most since his All-Pro season in 2015 (5).

Mathieu now has picks in back-to-back games as well.

4. Juan Thornhill brought a pick back to the house.

Thornhill also got in on the action, intercepting Carr late in the second quarter and returning it all the way back for a 46-yard touchdown.

Mathieu and Thornhill continued a trend for the Chiefs' defense against Carr, who has thrown 13 career picks – or 20 percent of his total interceptions – vs. Kansas City.

5. Rashad Fenton forced a fumble on special teams.

In what turned out to be a big night for the Chiefs' rookie class, cornerback Rashad Fenton created a turnover early in the game when he jarred the ball free from Raiders' return man Trevor Davis in kickoff coverage.

It marked the first forced fumble of Fenton's young career and his second takeaway of the season.

6. The Chiefs always seem to take the ball away in divisional matchups.

With three on Sunday, Kansas City now has 10 takeaways against AFC West opponents on the season, which are the second-most for any team vs. their own division in the NFL. That's been a trend for a while, too, as the Chiefs have forced a league-most 63 turnovers vs. divisional opponents since 2015. The next closest team, New England, is 10 takeaways behind.

7. Charvarius Ward returned a blocked extra-point the length of the field for two points.

In the type of play that simply doesn't occur very often, Ward picked up the blocked kick – courtesy of defensive end Tanoh Kpassagnon - and ran all the way to the other end zone to tally two points for Kansas City. It marked the first defensive two-point play by Kansas City since former safety Eric Berry intercepted an Atlanta Falcons' pass on a two-point try and brought it all the way back the other way in 2016.

Ward's play completed the ultimate team-victory for Kansas City, as the offense, defense and special teams units all found the end zone.

8. Patrick Mahomes set another record.

Mahomes didn't light up the stat sheet on Sunday, but he still managed to break yet another record. With one scoring strike to tailback Darrel Williams, Mahomes became the fastest player in NFL history to tally 70 touchdowns through the air, passing Pro Football Hall of Famer Dan Marino.

The reigning league MVP also notched his first rushing touchdown of the season on Sunday, scrambling for a 13-yard score early in the game.

9. Darwin Thompson scored the first touchdown of his career.

The rookie tailback pushed ahead for a 4-yard score late in the game for his first touchdown as a professional.

The score capped off a nine-minute and 32-second drive for the Chiefs, which marked Kansas City's second-longest touchdown drive since 1999.

10. LeSean McCoy tallied a pretty impressive career milestone.

McCoy caught his 500th career pass on Sunday, becoming one of just four tailbacks since 2000 to notch 500+ receptions during their career. Only LaDainian Tomlinson (624), Matt Forte (554) and Darren Sproles (553) have caught more passes out of the backfield than McCoy since the turn of the millennium.
