Who won the NASCAR race yesterday? Complete results for Sunday's Pocono race

The winner of Sunday's NASCAR Cup Series race at Pocono had just enough left in the tank to capture the checkered flag.

Kyle Busch risked running out of fuel in the closing laps to come home first in the Explore the Pocono Mountains 350, the nightcap of a weekend doubleheader at the track. William Byron and Denny Hamlin were ahead of Busch with three laps remaining but had to pit for fuel after running out.

Busch added the win to his second-place finish in Saturday's weekend-opening race at Pocono.

Who won the NASCAR race yesterday?

Kyle Busch's team gambled that the 18 car would have just enough fuel left in it after pitting with 46 laps to go, one lap later than Byron and Hamlin did. It turned out to be a winning call, but there was major concern right up until the final turn.

The team was also nervous about Busch's car not being able to get out of fourth gear because of a broken shifter.

"Yeah, stuck in fourth gear, about out of gas, just saving, just riding, playing the strategy the best we could with what was given to us," Busch said after the race, per NASCAR.com.

Denny Hamlin remains without a win this season despite leading the point standings.

"I mean, you're trying to win or you’re trying to get the best finish that you can," said Hamlin, who finished 14th. "But ultimately, we just didn’t save enough. The 18 I think came in and got topped off because he had transmission issues. That was essentially the race."

NASCAR results from Pocono

Kyle Busch earned his second win of the season by prevailing in a fuel-mileage duel. Kyle Larson came home second after starting the race at the rear of the field. The rest of the top five: Brad Keselowski, Kevin Harvick and Bubba Wallace, who earned his first top-five of the season.

Larson was starting at the back because he wrecked on the final lap of Saturday's race and had to go to a backup car Sunday. He was leading on the final turn Saturday when the left front tire on his No. 5 car went flat. His Hendrick Motorsports teammate Alex Bowman zoomed past for the win.

Next up for the Cup Series is a trip to Road America in Plymouth, Wis., for the Jockey Made in America 250 on Sunday, July 4 (2:30 p.m. ET; NBC, MRN, SiriusXM NASCAR Radio). The road course will be hosting a Cup race for the first time since 1956, per NASCAR.com.
