5:45 pm - Good Night - That's gonna do it for this weekend's coverage from the race track. Congratulations to Brad Keselowski, Ross Chastain and Grant Enfinger for their victories. Thank you for joining us and we'll see you back here in March!

5:00 pm - Truex Takes Points Lead - Martin Truex, Jr.'s third place finish boosted him into the points lead by two over Kyle Busch. Keselowski is in third place, 18 points behind the leader.

Busch clinched the regular season championship and had to battle back in today's race after an early pit miscue and a crash with less than 40 laps to go. Despite the trouble, Busch finished seventh.

"Our M&M's Camry guys did a great job fighting through that and getting me some good repairs and stuff like that on pit road," said Busch. "That's what this time of year is all about is minimizing the bad days and being able to recover and come back."

4:35 pm - Keselowski Wins Three in a Row - Brad Keselowski and the No. 2 team are on fire after winning their third race in a row, and it couldn't come at a better time in the season. In addition to scoring his 27th series victory, Keselowski also handed Team Penske its 500th victory overall. 

Keselowski led eight times for 75 laps, including the final 22 laps that saw the caution fly no less than four times. The No. 2 Ford was strong on the restarts, which was key to the victory.

"I didn't think it was ever gonna end," said Keselowski. "I was worried about running out of gas there at the end. What a special day for 500 wins for Penske, three in a row here, first win in the Playoffs. There are too many storylines for me to get it all right, but we're very thankful and very proud for all of them."

Playoff driver Kyle Larson finished second after rebounding from an early unscheduled pit stop for a flat tire. Larson swapped the lead back-and-forth Keselowski four times over the final 30 laps and ultimately finished 1.3 seconds behind the leader.

"I needed it to stay green," said Larson. "I was terrible on short runs today but once I could get the top going I was really good. Right when I moved up to the top in Turns 3 and 4 and pulled away the caution came out.
Martin Truex, Jr. led 21 more laps than the winner.

"Brad clearly found the horseshoe," said Truex. "Three races in a row he has won, he has not had the best car. He's on a streak. That's the way it goes."

"Well, there was something wrong from the time we put the tires on. It was like Russian roulette every time you put these piece of crap tires on and try to drive around the race track. One time it is tight, one time it is loose, one time they are blistered. We had a great car and then you put a set of tires on it and you can't hardly make it through the field. I just hate it for everyone on our Mobil 1 Ford."

9:50 am - Sizing Up the Big 3 - The "Big 3" Erik Jones identified as the favorites to run for this year's title are Kyle Busch, Kevin Harvick, and Martin Truex, Jr. Las Vegas' Kyle Busch, is a six-time winner in 2018 and kicks off the playoff season with the biggest advantage as the season's regular season champion.

Busch holds the record as the youngest Monster Energy Series winner and polesitter in LVMS history. He finished second to Harvick in March.

"I've won here before, but it was a long time ago," said Busch. "We'd love to have the opportunity to go out there and win and just move ourselves automatically through to the next round and not have to worry about the roval (at Charlotte)."

Harvick is looking for back-to-back LVMS wins. He dominated the March race, leading 214 of 267 laps. He has seven victories this season and has led 1,220 laps so far, more than any other driver.

Truex is a four-time winner in 2018 but is coming off a miserable performance at Indianapolis that saw him finish last with mechanical problems.

Busch starts today's race 4th on the grid. Harvick takes the green one lap back in 5th, while Truex qualified 10th.

9:00 am - South Point 400 Pre-Race - We are getting set to kick off the MENCS playoff season and Erik Jones, driver of the 20 DeWalt Toyota will lead the field to the green flag.

Jones readily admits that he may not be a favorite to run for the championship at Homestead but that doesn't mean the fans should count him out.

"I don't mind (being a dark horse)," said Jones. "I don't think it's wrong. You look at the three guys who have won all of the races and it's only been a few who have won a couple of races. I would say there's a few dark horses. I don't think I am the only one. I would say the big three are definitely the favorites to get to Homestead, but that last spot needs to be filled. We're all fighting for it."

The 16 playoff drivers qualified in the top 18 for today's race. Jamie McMurray (starting 12th) was the highest qualifying non-playoff driver. Ricky Stenhouse, Jr. crashed the playoff qualifying party with a 14th place qualifying effort.

Ross Chastain, yesterday's Xfinity Series race winner lines up 34th on the grid in the 15 Xchange of America Chevrolet.

Las Vegas Mayor Carolyn Goodman is on hand to welcome fans to today's events. As mentioned, NASCAR driver Brendan Gaughan will give the command to start engines on behalf of the South Point Hotel and Casino. Our flyover today will feature four A-10s from the 66th Weapons Squadron at Nellis Air Force Base.

7:45 am - Good Morning - For the Cup drivers it's all over but the racing. Las Vegas' own Brendan Gaughan will give the command to start engines at 12:07 pm and we'll set 'em loose for 267 laps. 

Stay tuned here for all the action as it happens.
