NASCAR Cup Series at Kentucky results: Rookie Cole Custer picks up first career win in wild finish

Here's what you need to know from Sunday's race at Kentucky Speedway

Cole Custer won the 2020 NASCAR Cup Series Quaker State 400 in a mad dash on the last lap to become the first rookie winner in nearly four years. The 22-year-old took the lead on the final lap to earn his first NASCAR Cup Series win in his 20th career start after a late restart at Kentucky Speedway. 

With the victory, Custer will have a spot in the All-Star race on Wednesday.

"We were so good all day, our car was so good," Custer told FS1 after the race. "That was the best car I've ever driven in my life. That was unbelievable."

Martin Truex Jr. finished second in Sunday's race. Matt DiBenedetto took third, and Kevin Harvick came in fourth.

Custer got a push from DiBenedetto on the outside down the backstretch, surging past Truex and Harvick, who were battling for the lead on the final restart. The move made Custer the first rookie Cup Series winner since Chris Buescher took the checkered flag at Pocono on Aug. 1, 2016.

After Jimmie Johnson became the first NASCAR Cup Series driver to test positive for the novel coronavirus (COVID-19), he was cleared to return to race at Kentucky, a rare track that he's never won at. Johnson finished 18th on Sunday, extending his Cup Series winless streak to 110 starts over 11 Cup Series races. His last win was at Dover International Speedway in June 2017.

The positive COVID-19 test also caused Johnson to miss the first race of his career at Indianapolis last week. This is Johnson's last full-time season in the Cup Series.

The Cup Series heads to Texas Motor Speedway for the O'Reilly Auto Parts 500 on Sunday, July 19. Before that, the Cup Series will host its All-Star festivities at Bristol Motor Speedway on Wednesday, July 15.
