8:50 pm - Friday Good Night - This concludes today's coverage from LVMS. Be sure to join us tomorrow for Cup Series qualifying, Xfinity Series qualifying and the Xfinity Series Rhino Pro 300. Good night!

8:35 pm - Austin Hill Records First LVMS Victory - Proving that it's never over until it's over, Austin Hill overcame what could have been a pit road miscue to win the Westgate 200 at Las Vegas Motor Speedway. The victory is Hill's first at LVMS and the third of his career in 70 series starts.

When the caution flew on Lap 80, Hill and his crew decided to stay on the track. When all the other leaders headed to pit road for fuel only, crew chief Scott Zipadelli made the decision to bring his driver in for tires and fuel.

That dropped Hill to 17th on the restart. With nothing to lose, Hill flew up through the field. When leader Ross Chastain wiggled with 12 laps to go, Hill was in the perfect position to take advantage of the bobble and take the lead. From there, it was no contest as Hill went on to beat Chastain to the checkers by 2.1 seconds.

"This was the hardest one I had to win," said Hill, who led six times for 29 laps. "We stayed out and everybody else pitted. So we decided we needed to pit or we were going to be screwed. Man, it stayed green. I had to drive all the way through the field. This truck was unbelievable."

Ross Chastain led 88 of 134 laps and won the first two segments but had to settle for the runner-up finish. Pole winner Christian Eckes finished third with Sheldon Creed and Todd Gilliland rounding out the top five.

Hill and Chastain both earned the right to advance to Round 2 of the Playoffs. They will be joined by Brett Moffitt, Stewart Friesen, Matt Crafton and Tyler Ankum.

ThorSport Racing teammates Grant Enfinger and Johnny Sauter were eliminated from title contention after engine failure put them behind the wall. Thorsport's third entry, the No. 88 driven by Matt Crafton also suffered engine failure but the points fell Crafton's way allowing his championship hopes to stay alive.

8:00 pm - Austin Hill Wins the Westgate 200 - Austin Hill cashed in on a big win in tonight's Westgate 200 to move on to Round 2 of the NASCAR Xfinity Series 2019 Playoffs. Hill battled back from a pit road miscue to take the lead with 11 laps to go and beat Ross Chastain to the checkers by 1.8 seconds. 

7:55 pm - Update, Lap 112 - Austin Hill takes advantage of a small wiggle by Chastain and sweeps into the lead with 11 laps to go. 

7:50 pm - Update, Lap 110 - Chastain continues to lead. He has about a 1.2-second advantage over Hill who flew up through the field after that pit miscue. 

3rd-5th: Eckes, Creed, Moffitt. 

7:35 pm - Back to Green - The drivers took advantage of that caution to come to pit road. Creed, Chastain, and Moffitt were among those that took on fuel only.

Hill had to make a second stop after a miscue. He'll drop to the rear for the restart. 

Top 5 for the restart is Chastain, Moffitt, Creed, Ankrum, Rhodes

Green flag on Lap 87 

7:27 pm - Under Caution, Lap 80 - We've slowed things down again. It's another engine issue and this times it's the No. 02 truck of Tyler Dippel. The Top 5, under caution, is Chastain, Creed, Moffitt, Rhodes and Burton. 

7:20 pm - Lap 69 Update - Sauter is done for good this time. He rolls to the garage. 

Back on the track: Moffitt, who has raced from last to first, chooses to restart on the inside lane. And we're back to green on Lap 73.

7:14 pm - Segment #3 - Green Flag - Brett Moffitt takes the lead on pit road. Behind him it's Eckes, Hill, Chastain, Poole, Gilliland, Creed, Rhodes, Ankrum, Burton

Sauter is back on the track. His crew thinks he had an oil leak. They're going to try to limp their truck along. 

We're back to green on Lap 67. And just like that, smoke pours out of Sauter's truck and we're back under caution. 

7:04 pm - Chastain Wins Segment #2 - Chastain hangs on to win the second segment.  Chastain's strong performance thus far puts him into Round Two of the Playoffs. 2nd-10th: Hill, Moffitt, Rhodes, Poole, Eckes, Creed, Gilliland, Ankrum, Dean. 

6:58 pm - Back to Green on Lap 46 - We're back to green flag racing with Hill leading the way. According to Crafton, the problem he and Sauter had was related to debris on the track. Sauter hit whatever it was first and then Crafton hit the same piece of debris. 

6:47 pm - Under Caution, Lap 41 - We are under caution as the remaining two Thorsport Motorsports' trucks blow engines at exactly the same time.  That will put Sauter and Crafton out of this race. Enfinger was already out of the race after blowing a rear seal. 

Top 5 under caution: Hill, Chastain, Moffitt, Eckes, Rhodes.

6:45 pm - Segment #2, Green Flag - After pit stops Hill takes the lead, followed by Burton, Chastain (who had a slow stop), Eckes, Creed, Sauter, Crafton, Ankrum, Gilliland and Moffitt. 

Stewart Friesen is the second Playoff driver to have trouble. Friesen's truck is down on power. The crew is replacing a plug wire, so he'll lose at least one lap on pit road. 

Safety violation for No. 5 - Lupton will restart at the rear of the field.

Back to Green on Lap 37

6:27 pm - Back to Green on Lap 13 - We are back to racing with Chastain on the point. 

Lap 14 - Moffitt has battled from the back of the field up to 12th. 

6:20 pm - Lap 5, Under Caution - Grant Enfinger brings out the first caution of the race as a huge plume of smoke erupts from his truck. Enfinger is a Playoff driver.

Eckes led the first 3 laps before he was passed for the lead by Chastain. Running 3rd through 5th under caution are Crafton, Hill and Creed.

Enfinger's truck was still running on pit road, so the engine's not dead yet. The crew is now trying to find the oil leak that caused the smoke and dampened the track.

6:05 pm - Westgate 200 - Green Flag - The engines are fired and we are ready to roll. Christian Eckes leads the field off pit road. 

John Hunter Nemechek's truck fails to roar to life and instead of joining the field on the track, his crew is pushing the No. 8 Chevrolet behind the wall. Nemechek was slated to start 11th. 

Moffitt is dropping to the rear of the field. His team had to change a flat tire. Moffitt gives up 4th on the grid to start last. 

Eckes starts on the inside lane and Green Flag!!

Eckes gets a push from Gilliland and takes the lead.

4:45 pm - NGOTS Westgate 200 Preview - This evening's NGOTS event marks the end of this year's Playoffs Round 1 and will trim the championship field from eight to six. Brian Moffitt is the defending Series champion and took a big step toward making it two-in-a-row with victories in the first two races of this round (Bristol and Canadian Tire Motorsport Park). If Moffitt can take the checkers, he will become the first driver to sweep a round since the Playoffs were introduced to the series in 2016.

Christian Eckes earned the right to lead the field to green with his second pole in 10 Truck Series starts. This is Eckes' first start at LVMS but he does have the advantage of driving for Kyle Busch Motorsports, the team that took their boss to Victory Lane in March. Starting alongside Eckes is Ross Chastain, who is ranked 2nd in the standings coming into this race.

Todd Gilliland and Brett Moffitt will line up on the second row, in 3rd and 4th, respectively. Moffitt leads the points and is the only driver who is locked in for Round 2. Moffit's peace of mind comes courtesy of his current two-race winning streak. He won the first race of this playoff at Bristol and made it back-to-back at Canadian Tire Motorsport Park. 

Moffitt's most recent race at LVMS ended with a runner-up finish to Kyle Busch in March. He finished 11th in this event last year.

Three drivers failed to qualify for tonight's event. They were Cory Roper, Justin Johnson and Tyler Hill.
