Martin Truex Jr. won the 17th Annual Hollywood Casino 400 on Sunday at Kansas Speedway, despite losing the lead on a restart violation after the competition yellow of stage one.

The win came after Truex won the pole position Friday in stage three of qualifying with a speed of 188.029 miles per hour around the one-and-a-half mile oval at Kansas City. Kevin Harvick started in the No. 2 position on the outside row.

Truex's No. 78 Toyota had no problem pulling away from the competition, leading all 30 laps until the competition yellow. Severe weather on Saturday night had washed the track clean and brought out the competition yellow on lap 30, allowing teams to check their settings.

Later in the race, Kyle Larson's No. 42 Chevrolet blew its engine on lap 78, bringing out the yellow caution flag until the end of stage one at lap 86.

After the penalties and a pit stop for a loose tire incurred by the 78 car, Kyle Busch and Kevin Harvick dominated the lead positions of stage two. These two drivers would be nose to tail much of the second stage. Busch's No. 18 Toyota pulled away with Harvick's Ford hot on his tail; Busch would lead 112 laps of the race, more than any other car. Harvick's No. 4 Ford led the first 35 laps of stage three, then Busch again took the lead.

The game-changing incident for four of the 12 Chase drivers took place on lap 199. Fourteen cars were involved in a crash in the backstretch. Erik Jones, in his No. 77 5-Hour Energy Toyota, started a chain reaction that took out Jamie McMurray, Matt Kenseth, Chase Elliott and Brad Keselowski. Kenseth's car would be disqualified for having too many men over the pit wall during repairs. McMurray's car was too far damaged to return to racing. Elliott and Keselowski continued and finished the race. Kenseth, McMurray, Ricky Stenhouse and Kyle Larson would be eliminated from the Chase.

The race was red flagged for 10 minutes to get the track cleaned up and cars removed. Truex again took the lead on lap 211 with only one caution period when A.J. Allmendinger had an incident in turn four. Truex went on to win with an average speed of 125.2 MPH, beating Kurt Busch by two seconds.

On Saturday, Christopher Bell won his first XFINITY race in the Kansas Lottery 300. Erik Jones, in the No. 20 Reser's Toyota, took the lead on the first lap and dominated the race. He would lead 186 of the 200 laps, the most at Kansas Speedway for an XFINITY race, and it seemed like no other car would come close to Jones in the windy conditions on Saturday. Severe weather was expected sometime in the early evening. Only two yellow cautions were shown for incidents in the 300-mile race. The two other cautions were shown for the conclusions of the first two stages.

Bell would catch Jones on lap 196 and pass for the lead. Jones' car bumped into the rear end of Bell and damaged his own car to the extent that he finished 15th in the race. Bell took the checkered flag with a two-and-a-half second margin over Tyler Reddick. Bell's average speed was over 141 MPH, completing the race in just over two hours and seven minutes.
