Martin Truex Jr. took the lead with two laps remaining in Stage 2 of the South Point 400 as Joey Logano got caught up in lapped traffic, and the driver of the No. 19 Joe Gibbs Racing Toyota went on to collect his fourth stage win of the season on Sunday.
Logano, who had led 72 laps of the 80-lap stage, finished second in the stage.

Kyle Larson, Kevin Harvick and Chase Elliott rounded out the top five in the stage as the top 11 finishers were playoff drivers.
Erik Jones had trouble with his throttle on the Stage 2 restart, and his No. 20 Joe Gibbs Racing Toyota reportedly was stuck in second gear. He came to pit road on Lap 87 for repairs, and then went to the garage.
He returned to the track on Lap 102, but was 15 laps down — last in the 39-car field. He finished the stage 14 laps down.
Kyle Busch attempted to better his position on track after his early race incident knocked him a lap down, but his strategy to delay his pit stop was foiled when no cautions came during the stage. He finished Stage 2 in 28th place, two laps down.
Polesitter Clint Bowyer also slowed during Stage 2, dropping to 20th and one lap down.
The race is scheduled to end on Lap 267.

Logano, the defending Monster Energy NASCAR Cup Series Champion, is also the most recent winner at Las Vegas, having won at the 1.5-mile track in March.
Stewart-Haas Racing teammates Kevin Harvick, Aric Almirola and Daniel Suarez finished 2-3-4 behind Logano in the stage. Suarez and Austin Dillon were the lone non-playoff drivers to score stage points.
Regular season champion Kyle Busch encountered early trouble when he got loose on Lap 5 and his No. 18 Joe Gibbs Racing Toyota scraped the outside wall. He made an unscheduled pit stop on Lap 11 for his crew to make repairs and change right-side tires, and went down a lap early. Though he exited pit road 39th out of 39 cars, he finished Stage 1 in 29th and two laps down — lowest among the 16 drivers in the playoffs.
