LAS VEGAS – Kurt Busch was struggling in dirty air early in Sunday’s Pennzoil 400 at Las Vegas Motor Speedway.

The solution? Trade the dirty air for clean air at the front of the pack.

Busch and crew chief Matt McCall opted to stay on track as long as possible during the second stage of the race, pitting for tires and fuel with 15 laps left in the segment. That enable Busch to keep his No. 1 Chip Ganassi Racing Chevrolet on the track while others came to pit road for the stage break.

Busch led the field to green on Lap 168 before losing the lead briefly to eventual race winner Joey Logano for one lap. Busch then held the top spot on older tires despite huge pressure from Kevin Harvick before Harvick took the lead on Lap 188. Busch held on for a fifth-place finish in his third race with his new team.

“We got really tight in traffic, and our pit strategist was saying that, if we stayed long in the second stage, then we could stay out,” Busch said. “It played out to where we got clean air, and it completely changed the complexion of the car…

“It gave us a lot to learn from today, and I’m really proud of everybody to get a top five. Now we’ve got two top fives to year, but we know we’ve got some more work to do.”

The race-winning Team Penske No. 22 Ford of Joey Logano passed post-race inspection at Las Vegas Motor Speedway with no issues.

The No. 22 was found to be compliant with the NASCAR Rule Book. With the post-race teardown complete, the race results are official.

Two cars were found with one unsecured lug nut — the No. 95 Leavine Family Racing Toyota of Matt DiBenedetto, who finished 21st, and the No. 41 Stewart-Haas Racing Ford of Daniel Suarez, who finished 17th. The penalty for that typically is just a fine to the crew chief and is announced Monday.

The post-race process is part of a new, more timely approach to inspection for all three NASCAR national series. Competition officials announced in February that thorough post-race inspections would take place shortly after the checkered flag at the track instead of midweek at the NASCAR Research & Development Center in Concord, North Carolina.

Those inspections come with a stiffer deterrence structure that includes disqualification for significant rules infractions — “a total culture change,” according to Steve O’Donnell, NASCAR Executive Vice President and Chief Racing Development Officer. In the past, race-winning teams found in violation of the rules were penalized with post-race fines, points deductions and/or suspensions, but victories were allowed to stand.

Competition officials introduced the quicker post-race inspection timetable in an effort to make the results official on race day, aiming for a 90-minute target time frame to complete their scrutiny. The new post-race inspection process also was designed to deal with potential violations more promptly, avoiding any midweek news that might cloud the previous week’s results or the build-up to the following week’s event.

NASCAR will still inspect cars and parts at the R&D Center as needed, but the more comprehensive at-track inspection will take priority.

According to NASCAR statistical archives, the last time a premier series driver was disqualified occurred in 1973, when early retiree Buddy Baker was demoted to last place in the National 500 at Charlotte Motor Speedway. The last time an apparent race winner in NASCAR’s top division was disqualified came on April 17, 1960, when Emanuel Zervakis’ victory at Wilson (N.C.) Speedway was thrown out because of an oversized fuel tank on his No. 85 Chevrolet.

Kyle Busch had just taken the lead midway through the Pennzoil 400 at Las Vegas Motor Speedway and seemed headed toward his third win in three days at his hometown track when he brought his No. 18 Joe Gibbs Racing Toyota in for a green-flag pit stop.

That routine move proved to be his undoing in thwarting his attempt at a tripleheader sweep when he came onto pit road too fast, smoke billowing and tires screeching.

Busch was nabbed for traveling too fast on pit road on Lap 129 of the 267-lap race, and forced to serve a pass-through penalty.

Busch fell to 24th and one lap down after the mistake, but it didn’t mean the end of his opportunity at the trophy. He managed to work his way into the top five with about 65 laps remaining, but couldn’t manage one final push to the lead as he was held up by the lapped car of Corey LaJoie. He finished third.

“I certainly screwed up our day coming to pit road there,” he said after the race. “We tried a different brake package for us this weekend and trying to make up time in order to get a bigger jump on the guys behind me coming to pit road there and just ruined it for us and we had to come from the back. I think we passed the most cars today so I think we were the most impressive today, but that doesn’t matter because we don’t have a trophy.”

His crew chief Adam Stevens did take positives from the speed of the No. 18 Toyota, as it rallied from the back.

“Mistakes happen, you know,” Stevens said of the pit road error after the race. “He just got into pit road a little hot, locked ’em up and couldn’t get slowed down in time and sped in the first section. It’s not the first time we’ve seen that in this sport. He was trying to get all he could get. It’s part of it.

“But (we’re) pleased with the speed we had in our car and the balance was close, so as a team I felt like we did a good job, and he did a good job on the race track overcoming from that. Kind of ran out of laps there. I think we had speed equal to the car that finished in front of us, but kind of gave our track position away.”

Busch is the only driver in NASCAR history to have won races in three national series at the same track in the same weekend. Both of those came at Bristol Motor Speedway, first in 2010 and most recently in 2017.

Team Penske drivers Brad Keselowski and Joey Logano swapped the lead three times over the final 40 laps of Sunday’s Monster Energy NASCAR Cup Series race at Las Vega Motor Speedway.

For a moment, it appeared there would be a fourth — coming out of Turn 4 on the final lap.

But Keselowski’s sweeping, attempted slide job just missed the mark as last week’s race winner took second place in the No. 2 Ford, watching teammate and defending series champion Logano win his first race of the year.

Keselowski caught and passed Logano for the lead on Lap 240, then lost it back to the No. 22 Ford on Lap 244. But Keselowski cut significantly into Logano’s lead with just two laps to go, then timed his last-gasp move nearly perfectly.

“I passed Joey with the lapped traffic there and caught a break there, and then lapped traffic cost me the lead to Joey and he pulled a good slide job,” Keselowski told FOX reporters after the race. “I tried to pull it back, and I was just a touch too nice to him.”

The implication, of course, is that Keselowski could have initiated contact or even wrecked the No. 22 vying for the win. As it stands, the teammates finished 1-2 for the fifth time in their respective careers.

That both cars had plenty of speed set up both the last-lap showdown, and also could portend future strong showings between the two — and perhaps similar finishes.

“Brad’s been doing a good job of doing that late in the race of getting all he can out of it, and we’ve had some really good cars, so that’s encouraging,” No. 2 crew chief Paul Wolfe said. “It was good racing with the 22, obviously. Brad’s pretty respectful of his teammates, and Joey’s been that way. I thought he raced him hard, but raced him clean. Thought it was a good race there at the end.”

LAS VEGAS – It was a victory for Joey Logano.

It was a victory for Team Penske.

It was a victory for NASCAR’s new higher-downforce, lower-horsepower competition package, which debuted in full flower Sunday at Las Vegas Motor Speedway.

In a pitched battle between teammates, Logano held off Brad Keselowski on the final lap of the Pennzoil 400 to score the second straight victory for Team Penske and the second straight for the new Ford Mustang, which was introduced into the Monster Energy NASCAR Cup Series this year.

Pennzoil sponsored both the race and Logano’s car.

“I said we’re going to do donuts on that giant infield logo after the race, and we were able to do it,” said Logano, who won for the first time this season, the first time at Las Vegas and the 22nd time in his career.

“What a great race. Brad and I were so evenly matched, and you just can’t drive away (with the lead). In the last five or six laps, Brad was catching me so quick, and I got stuck behind a lapped car. Man, it was so close. Lots of fun – my heart’s still running hard.”

Keselowski, who won last week at Atlanta, had a huge run through Turns 3 and 4 on the final lap, but Logano was able to clear his teammate off the final corner – with inches to spare – straighten his No. 22 Ford and head for the checkered flag.

“Yeah, I figured he’d run up against the wall there, and he made up more ground than I thought he would,” Logano said. “He made such a good run and I just barely cleared him there at the end.

“Team Penske going 1-2 shows the kind of speed we’ve got this season.”

RELATED: Keselowski: ‘Touch too nice’ to Logano

On Lap 240 of 267 in a race whose only two cautions were the breaks between stages, Keselowski passed Logano in traffic to take the lead. Four laps later, Logano returned the favor and held the top spot the rest of the way.

“It was a good battle,” Keselowski said. “We were both running really hard on the top. It seemed to come down to what the lapped cars were going to do. The lapped cars screwed the leader, and the second-place guy got a really good run.

“It happened over and over again. First, Joey got hosed by a lapped car, and I got by him. Then I got hosed by a lapped car, and he got by me. But it was definitely a good event.”

In the end, the event came down to the final few laps, with Keselowski trimming Logano’s lead from just over a second to next-to-nothing with two laps left. Keselowski’s last-ditch try through the final two corners came up just short. The driver of the No. 2 Ford would have liked one more lap to settle the issue.

“I’d sure like to find out,” Keselowski said. “I passed Joey with the lapped traffic there and caught a break there, and then lapped traffic cost me the lead to Joey and he pulled a good slide job (off Turn 4 on the final lap).

“I tried to pull it back, and I was just a touch too nice to him.”

Kyle Busch recovered from a pit road speeding penalty to run third, his chances to make the final run a three-way fight for the win ending when he ran afoul of traffic on the final three laps. Pole winner Kevin Harvick dominated the first stage, but the handling of his No. 4 Ford deteriorated in the second half of the race, as it had done last week at Atlanta. He finished fourth.

RELATED: Busch’s sweep falls short

Kurt Busch parlayed a divergent pit strategy into a fifth-place run. Ricky Stenhouse Jr., Aric Almirola, Martin Truex Jr., Chase Elliott and Daytona 500 winner Denny Hamlin completed the top 10.

Logano led 86 laps, second only to Harvick’s 88. With the race running green except for the stage breaks, 18 cars finished on the lead lap.

The new competition package kept the racing closer at the front and more fluid within the pack. The event produced 47 green-flag passes for the lead versus nine in last year’s race. All told, there were 19 lead changes at the completion of laps as opposed to 11 in 2018.

Seventeen drivers each accounted for more than 100 green-flag passes, according to NASCAR’s loop data.

Joey Logano, looking for his first Las Vegas win, took home Stage 2 in Sunday’s Pennzoil 400 presented by Jiffy Lube at Las Vegas Motor Speedway.

The lead traded hands several times between Logano, Brad Keselowski, Kyle Busch and William Byron after Kevin Harvick dominated Stage 1. It was Logano that wound up with the stage win, however, aided by a costly penalty by Busch.

Kevin Harvick, Martin Truex Jr., Keselowski and Denny Hamlin rounded out the top five.

Keselowski took two tires during stage break to come off pit road first before ceding the lead to Logano on Lap 97. Busch then worked his way in front of Logano’s No. 22 Ford takes the lead on Lap 112, before Logano took it right back.

Busch re-inherited the lead on Lap 120, but got hit with a speeding penalty on Lap 129 to put a damper on his attempt to sweep the weekend at his home track. He worked his way back up to 18th by the end of the stage, however.

During green flag cycles, Byron took over at the front of the field to lead 21 laps before his pit cycle washed him back to a still-respectable 11th. Logano re-took the lead upon the No. 24’s pitting, and cruised the rest of the way.

The Final Stage is scheduled for 107 laps.

STAGE 1

Kevin Harvick cruised to his second stage win of the season when he took advantage of his pole position to dominate Stage 1 Sunday in the Pennzoil 400 presented by Jiffy Lube at Las Vegas Motor Speedway.

The Stewart-Haas Racing driver and defending race-winner earned the Busch Pole on Friday, helping him lead 62 laps in the opening stage of the third race of the Monster Energy NASCAR Cup Series season.

Kyle Busch, going for the weekend sweep in his hometown after winning the Gander Outdoors Truck Series and Xfinity Series races earlier this weekend, was second.

Joey Logano, who has six straight top-10 finishes at Vegas, placed third.

During green flag pit stops, Austin Dillon and Kyle Larson were hit with penalties for having too many men over the wall. They started fourth and seventh, respectively, but both wound up missing out on stage points. Michael McDowell’s team was later penalized for having his crew over the wall too soon.

Harvick’s SHR teammate Daniel Suarez led 12 laps after Harvick came in for his scheduled stop. The third-year-driver placed ninth in the stage.

Ryan Blaney was forced to come back down pit road on Lap 51 after he had a left rear tire going down. He sits 30th.

The No. 13 Germain Racing Chevrolet of driver Ty Dillon and No. 00 StarCom Motorsports Racing Chevrolet of driver Landon Cassill both will start Sunday’s Monster Energy NASCAR Cup Series race at Las Vegas Motor Speedway (3:30 p.m. ET, FOX, PRN, SiriusXM NASCAR Radio) from the rear of the field following unapproved adjustments.

The No. 00 team changed a gear Sunday and the No. 13 team swapped in a new engine.

PHOTOS: Lineup, team rosters

Dillon had qualified 14th, his best starting position since the Texas spring race in 2017. Cassill qualified 31st. The drivers officially will “keep” their starting positions, but will roll to the back of the field on the warm-up laps.

This story will be updated if other cars are forced to start from the rear.

Richard Childress Racing drivers Austin Dillon and Sunoco Rookie of the Year contender Daniel Hemric are the biggest movers on the Las Vegas odds board prior to Sunday’s Monster Energy NASCAR Cup Series race (3:30 p.m. ET, FOX, PRN, SiriusXM NASCAR Radio).

After Dillon opened at 70-1 odds (meaning a bet of $100 would win $7,000, should AD win on Sunday) on Tuesday, he’s now a 30-1 favorite after leading both the opening practice Friday and the lone practice Saturday afternoon in Sin City. Dillon also qualified fourth for today’s race, and his 30-1 odds equal those of Jimmie Johnson and are better than Daniel Suarez, Ricky Stenhouse Jr. and Alex Bowman.

Hemric is an even bigger move. Opening at 125-1 odds, the driver of the No. 8 Chevrolet now is 70-1 — a huge jump for the rookie still looking for his first win in a NASCAR national series start. Hemric finished second to Dillon in both practices, and he qualified fifth. His Chevrolet and Dillon’s No. 3 ran the draft beautifully at Las Vegas, which utilizes both tapered spacers to target 550 horsepower and aero ducts to foster tighter racing.

Other notes on the pre-race odds updates:

Kevin Harvick still is the race favorite, but dropped from 5-1 at open to 11-2.

Clint Bowyer is one of the biggest fallers, going from 16-1 to 25-1.

Despite qualifying eighth and posting the third-fastest time in final practice, Ricky Stenhouse Jr. fell from 40-1 to 60-1.

Hendrick Motorsports driver William Byron plummeted, going from 66-1 to 100-1.

NASCAR is in the hometown of newly signed Philadelphia Phillies outfielder Bryce Harper this weekend — yes I am a big fan of that team as followers on Twitter know all too well — and Stewart-Haas Racing’s Kevin Harvick will start from the pole position for Sunday’s Pennzoil 400 presented by Jiffy Lube at Las Vegas Motor Speedway (3:30 p.m. ET on FOX, PRN, SiriusXM NASCAR Radio).

Once again, I’ve ripped up most of my original lineup from the start of the week after seeing a taste of the new rules package on display. I’m keeping two Penske cars given how well they have run at Las Vegas in the past. Keselowski has three Las Vegas wins since 2014 and had the third-best 10-lap averages in final practice. Yes, he’s starting 19th, but I think we’ll see some movers from the middle on Sunday. Logano has been a top-10 machine at Las Vegas, will line up 10th on Sunday and has 27 stage points in the three previous Vegas races.

The Richard Childress Racing camp has looked stout this weekend with Dillon and Hemric topping both practice sessions and both atop the 10-lap board in final practice. I will acknowledge that it’s risky relying on both in your lineup, but the RCR group has found something early on with this package. The strongest reason to play them is the lack of ownership across leagues as of Saturday at 8:50 p.m. ET; Dillon was owned by 12 percent of players and Hemric by 5 percent. A real chance to gain points others might not if you believe they are for real.

The decision to play both RCR cars leads me to put an experienced hand in the garage, so I am tapping Harvick. He is on the pole, and Harvick won the 2018 All-Star Race where this package outline was first used. I preferred to save Harvick heading into the weekend, but the pole position swayed me. Truex seems a little off, and I’d like to save Kyle Busch for a host of upcoming tracks — ISM Raceway (Phoenix), Fontana, Martinsville, Bristol and Richmond. The uses with him are going to stack up real fast, so I will be more conservative with him early on.

The last spot in my lineup was a toss up between Ryan Blaney and Erik Jones. Blaney has the better Vegas history and starting spot but Jones had the better 10-lap average by quite a bit in final practice — sixth vs. 24th. I’ve also yet to use Jones this season — same with Blaney — and I want the last spot I have to be a driver I’ve yet to use. Giving the nod to Jones for now.

For the stage winners, I’m going Harvick in Stage 1, Logano in Stage 2 with Kyle Busch winning the race as a hedge for not having him in my lineup.

Each week in this space, we’ll also highlight two Props Challenge items for players.

MORE: Play the Props Challenge today

1. The average starting position for the last three Las Vegas March winners is 2.67. O/U starting position of 4.5 for this year’s winner? I like the under here and it’s largely because the top four consists of Kevin Harvick, Denny Hamlin, Kyle Busch and Austin Dillon. Harvick and Busch both have wins at Las Vegas and Dillon had shown speed all weekend long. Hamlin has yet to win at Las Vegas, but I like having Harvick and Busch in the top four of this prop.

2. After showing speed at Atlanta, will rookie Daniel Hemric finish in the top 15? I am a resounding yes for this one. He and Richard Childress Racing teammate Austin Dillon have been fast all weekend as RCR has finished 1-2 in both practices. Hemric also topped the 10-lap board in final practice and qualified fifth. He enjoyed a really good run at Atlanta before a cut tire ruined his finish. I’m in on Hemric maintaining a top-15 spot throughout the race and finishing in the top 15.
