Briscoe lost the lead late in Saturday’s Pennzoil 150 only to come back and went three-wide with then-leader A.J. Allmendinger and Austin Cindric with two laps remaining and emerged the leader.
Briscoe then quickly began to pull away as the battle for position heated up behind him and he held off Justin Haley to win the inaugural NASCAR Xfinity Series race on the Indianapolis Motor Speedway road course.
The win is the fifth this season for the 25-year-old driver from Mitchell, Ind., which ranks as the second-most wins in series history in the first 13 races. Hall of Famer Sam Ard won six of the first 13 races in the 1984 season.
“Everybody knows that I grew up and my hero in racing was Tony Stewart. To get to drive for him and watch him win the Brickyard, that was always his signature thing and I just wanted to do it. Obviously it is not the same prestige as winning on the oval but you still won at Indianapolis Motor Speedway,” Briscoe said. “It doesn’t matter if you are racing on the oval, the road course, the dirt track or even the parking lot, it is special when you win here.
“Growing up, coming here all the time, it is unbelievable to think that I just won here.”
Asked if he considered this the most significant win of his career, Briscoe said, “From a personal standpoint, Darlington meant a ton just because of what I was going through. I have dreamed of coming to this race track and just getting to race here. To win here is unbelievable. I can’t put it into words. To get our sponsors in Victory Lane and driving for Stewart-Haas at Indianapolis.
“It doesn’t get any better than that.”
