Joey Logano took the checkered flag in his #22 Team Penske Ford after successfully defending a challenge from teammate Brad Keselowski, who won last Sunday's race at Atlanta Motor Speedway, in the final turn of the final lap of the race.
Logano finished in the top three in both stages, winning stage two before winning the race itself.
Joey Logano raced to victory at Las Vegas Motor Speedway to pick up his first win of the NASCAR season.
His brother Kurt Busch ended up fifth after climbing to the front of the field with an alternate strategy adopted at the end of stage two. Logano passed his Team Penske team-mate for first on lap 97.
Busch will start third at the Pennzoil 400 on Sunday. The favorites - Kevin Harvick and Kyle Busch - are no strangers to this race but have plenty of others to contend with.
Busch had to bounce back from falling to 33rd place during an early unscheduled pit stop due to a loose wheel, but the veteran Cup Series driver rolled back into the lead and still led 98 laps. Logano won the race at the track in November of 2016.
Jose Mourinho: I always put the club’s needs first
More than two months on from his sacking, Mourinho has revealed that he fell out with Pogba because of his own need to be "a club man".
"The second half of the race, it's happened to us two weeks in a row", Harvick said. He also led 17 laps and received 43 points. "We got a lucky break with that caution in the second stage that got us back on cycle". In a ideal world, the changes will lead to increased drafting, a bit of door-banging, and more exciting finishes in a sport that already has much more parity and late-race excitement than the likes of Formula One.
Pole victor Kevin Harvick led a race-high 88 laps to finish fourth and Kurt Busch completed the Top 5. "We just still need that power feel of that attack to make sure we are the ones making the right call instead of trying to piece together the calls". When we get some baseline stuff here, we can start working on the details and not scrambling so much.
Joe Gibbs Racing's Kyle Busch needed a win at his home track to complete a weekend sweep of the three NASCAR races at Vegas.
"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 where we got clean air and it completely changed the complexion of the auto".
"It gave us a lot to learn from today, and I'm really proud of everybody to get a top five". If you sign up to a service by clicking one of the links, we may earn a referral fee.
