The Joe Gibbs Racing pilot jumped 11 spots over the course of Sunday's Pennzoil 400 to secure his sixth top-five finish in front of his hometown crowd at Las Vegas Motor Speedway.
The seven-time Monster Energy NASCAR Cup Series champion entered the race a dismal 35th in the standings after crashes in the first two races of the season, at Daytona and Atlanta. The Stewart Haas Racing star led the most laps of any Las Vegas victor ever with 214.
"It's early, this is only race three - we aren't anxious yet", Busch said.
From his dynamic opening laps to his comfortable cruise to the checkered flag, Kevin Harvick was the safest bet in Sin City this weekend. It's good to score playoff points because we saw how important they were previous year for the 78. when things are going good, you need to hammer it home.

Turkish soldiers, 116 FSA militants killed in Afrin Operation
Late on Thursday, the Turkish military said eight Turkish soldiers had been killed and 13 injured in clashes in Afrin. PKK has fought for independence in South-Eastern Turkey since 1978 but the YPG has denied any links to the group.
Harvick started the day strong, leading 72 of the first 82 laps to win Stage 1 at Las Vegas. This year marks the first time in the sport's history that the speedway will host two races in a season. Kyle Busch won the Cup race in 2009, but he also has victories there in the Xfinity Series and the Truck Series race, which he won Friday night.
The cycle of stops were completed on Lap 51 and Harvick remained in the lead but his advantage over Truex had dropped to under a second.
Kirt Busch spun on Lap 183, collecting Chase Elliott in the process after both had run in the top 10 most of the day. "By the time we come back in September and you look at the downforce and things the auto makes at that time compared to the beginning of the year - if you look at what we raced here last year compared to what we will race today - is all progression [throughout] the year".
"At the end of a year ago, and even in Atlanta, I was trying too hard", Johnson said. The 39-year-old Busch has never won at Las Vegas Motor Speedway, which was built while he grew up in town.
