5:00 pm - Good Night - That will do it for today's coverage from the track. Please join us tomorrow for the Cup Series Pennzoil 400 and Kyle Busch's attempt for the hometown weekend sweep. 

4:30 pm - Christopher Bell Leads Points - Christopher Bell takes an 18-point lead over Cole Custer into next weekend's race in Phoenix. Bell led two times for three laps and finished 13th after being collected in the crash that brought out the final caution.

3:54 pm -  Kyle Busch Wins Boyd Gaming 300 - Kyle Busch hung on through a pair of overtime restarts to record career Xfinity series win #93 and complete the 2nd leg of the Las Vegas weekend tripleheader. 

John Hunter Nemechek finished second with Noah Gragson, Austin Dillon, and Michael Annett rounding out the top five. 

The results show that Busch led 98 of 213 laps but that hardly tells the story. An unscheduled pit stop under green for a loose wheel put Busch a lap behind the leaders before 15 laps were in the books. Unfortunately for the competition, it was only a minor setback for the series' most successful driver.

A well-timed caution on Lap 60 helped Busch make up the lap, and it was just a matter of time before he was leading the way. Crashes in the closing laps sent the race into double-overtime but Busch was able to hold off Tyler Reddick and then John Hunter Nemechek to record his second series victory at his home track.

"I just knew to keep fighting and keep working," said Busch. "We got lucky with that caution and we were able to get back on the lead lap. It's cool to come out here and have the opportunity to race in front of my hometown."

John Hunter Nemechek gave it all he had on the final restart. For a split second, it looked like he was going to clear Busch on the backstretch. 

"I was hoping Austin Dillon was going to be able to come back and give me a little bit of a push there," said Nemechek. "But the 1 (Michael Annett) got to his (Busch's corner) and the 18 and I were side-by-side, stalling out. The the 1 car gave him a huge push, that's for sure. I gave him a run for his money."

3:45 pm - Under Caution on Lap 207 - Restart on Lap 206: Reddick was racing Busch side by side in Turn 4 for the lead when Reddick got loose and spun out, collecting Smith and Bell in the process. Busch drove away but the caution flies before he can get to the white flag. So we'll do it all again. 

Running order for restart: Busch, Nemechek, Dillon, Annett, Sieg, Gragson, Brisco, Custer, Chastain

3:35 pm - Under Caution on Lap 199 - We were within one lap of finishing the race when Jones crashed hard to bring out the caution and send the event to over time. Jones was running fifth at the time.

2:05 pm - Lap 60, Under Caution - We're under caution for a crash involving Smith and Cindric. Smith got a little loose underneath Cindric and clipped the corner of the No. 22 Ford. Cindric barely taps the outside wall and then is lucky to avoid traffic as he sweeps back across the track.

Custer takes the lead and just as we complete Lap 1, wee're under caution for the first time. Joey Gase and Donald Theetge crash hard in Turns 3 & 4. The entire front end of Gase's car is demolished. Gase must be OK because he's asking his spotter for guidance since he can't see past the pushed up hood blocking his windshield. 

Running order under caution: Custer, Cendric, Allgaier, Jones, Busch

1:10 pm- Boyd Gaming 300 Pre-Race - The driver's have been introduced, the sun is peeking through the clouds, and we are about ready to go racing in today's Boyd Gaming 300.

This is the 24th Xfinity Series race at LVMS. We have seen 11 different winners in the last 11 races. Three former winners in today's field are anxious to break that streak they are Kyle Busch (2016 winner), Ross Chastain (2018 winner) and Austin Dillon (2015 winner).  

Jeff Green is the only other former winner in the field. Green is the man who christened Victory Lane for the series back in 1997.

We'll go racing for 200 laps (300 miles) with Stage 1 ending on Lap 45 and Stage 2 ending on Lap 90.

12:30 pm - Dillon Leads Final Practice - Austin Dillon and Dale Hemric laid own their quickest laps in the opening minutes of the session and no one else could catch them. Rick Stenhouse, Jr. was third quickest and ran 61 laps, which was more than any other driver. Aric Almirola and Brad Keselowski were fourth and fifth fastest respectively. The Busch Brothers ended the session in the top 10 with Kurt 7th quickest and younger brother Kyle 9th overall. 

11:30 am - Cup Final Practice Underway - We're back on track with the final Cup practice of the weekend. Richard Childress Racing's Austin Dillon and Dale Hemric are the early leaders. 

9:45 am - Xfinity Qualifying Cancelled - The rain has stopped for now, but in the interest of time, NASCAR officials have cancelled Xfinity qualifying. We're gonna line up the grid based on owner points and that puts Cole Custer on the pole and Chad Finchum starting second. Kyle Busch's quest for the weekend tripleheader begins eighth in (hopefully) this afternoon's race. 

When the track is ready, we'll get the Cup drivers on track for their final practice. 

9:00 am - Cup Practice Cancelled - Good morning from a slightly soggy speedway. On-track activities are on hold for showers in the area, although track-drying efforts have begun. 

NASCAR officials have already scrubbed this morning's Cup Series second practice, which was scheduled for 55 minutes beginning at 8:30 am. 

The forecast looks promising with Weather Channel predicting the winds to pick up and the rain to move out entirely by 3:00 pm. But the weather in Southern Nevada is notoriously unpredictable, and let's not forget it was snowing on the Strip just last week. 

The good news is we do have lights, and we're not afraid to use 'em. So stay tuned and we'll keep you updated throughout the day.
