Chastain took the field three-wide on a restart with 16 of 267 laps to move into the lead but Logano – among a group of cars that had pit for new tires during the previous caution – was coming up fast through the field.
Logano finally caught Chastain with two laps to go and easily made his way around him to reclaim the lead and held on by 0.817 seconds for the victory.
With the win, Logano automatically advances to the Championship 4 at Phoenix and will compete for the 2022 series title regardless of how he finishes in the next two races – next weekend at Homestead, Fla., and Oct. 30 at Martinsville, Va.
The driver who has won the first race of the semifinal round of the playoffs has gone on to win the championship in three of the last four seasons.
“We’re running for a championship – let’s go,” Logano said after exiting his No. 22 Ford. “The Penske cars were all really fast today. All you want to do is get to the Championship 4 when the season starts and race for a championship and we’ve got the team to do it. I don’t see why we can’t win at this point.
“Things are looking really good for us, and man, just a lot of adversity fought through the last 50 laps or so. I thought we were going to win and then we kind of fell out and then had the tires, and racing Ross was fun.
“He was doing a good job air blocking me, and just trying to be patient, and eventually I was like, ‘I’ve got to go here.’ Just great to win out here in Vegas again, and it means so much getting to the championship.”
Kyle Busch finished third, Chase Briscoe rebounded from a lap down to finish fourth and Denny Hamlin rounded out the top-five.
Completing the top-10 were Tyler Reddick, Martin Truex Jr., Erik Jones, A.J. Allmendinger and Austin Dillon.
With two races remaining in the semifinal round of the playoffs, the four drivers lowest in points and in danger of elimination are William Byron, Briscoe, Ryan Blaney and Christopher Bell.
Both Blaney and Bell were involved in wrecks in Sunday’s race.
During the break between Stages 2 and 3, the lead-lap cars all pit with Logano first off pit road. Ty Gibbs was penalized for speeding on pit road and had to restart from the rear of the field. Daniel Suarez was forced to pit twice to tighten a wheel.

The lead-lap cars all pit with Haley first off pit road thanks to a two-tire pit call. After his stop, Busch had the left-front wheel come off his No. 18 Toyota, which will likely result in a four-week suspension for his crew chief.
On the restart on Lap 233, Justin Haley was followed by Chastain, Almirola and Byron.
Suarez spun off Turn 4 and slid down the frontstretch on Lap 240 which brought out the seventh caution of the race.
Several drivers elected to pit but Haley remained on the track and in the lead on the restart with 22 to go. He was followed by Briscoe, Reddick, Chastain and Harvick. Logano, the first off pit road among those who pit, restarted 13th.
Just after Briscoe cleared Haley for the lead on the restart, NASCAR displayed the caution again as Landon Cassill wrecked in Turn 4.
Byron elected to pit for new tires during the caution. On the restart on Lap 252, Briscoe led the way followed by Haley, Chastain, Truex and Allmendinger.

With two laps to go, Logano caught Chastain and cleanly passed him for the lead.
Blaney held off teammate Logano by 1.5 seconds to take the win in an eventful Stage 2.

During the break between Stages 1 and 2, the lead-lap cars all pit with Bubba Wallace first off pit road.
On the restart on Lap 86, Wallace was followed by Suarez, Logano and Truex.
Suarez powered to the lead on the restart as Chastain moved into second and Wallace dropped to third.
On Lap 95, Kyle Larson ran up into Wallace and knocked him into the wall. As Wallace came back down the track, he slammed into Larson’s No. 5 Chevrolet, leaving both cars knocked out of the race.
After exiting his car, Wallace walked over to Larson’s wrecked car and the two got into a brief shoving match on the frontstretch before they were separated. Playoff driver Bell was also collected in the incident on the track.

Reddick started on the pole and race side-by-side with Cindric for two laps until he cleared for the lead on Lap 3.
With 50 laps remaining in the first stage, Reddick held a small but steady lead over Cindric as Blaney moved up to third.
On Lap 34, Cindric cleared Reddick in Turns 1-2 to take the lead just as a handful of cars hit pit road to kick off a round of green-flag pit stops.
