Briscoe overcame a pit road speeding penalty, spun out while leading at one point and used a nudge and pass of Ross Chastain with one lap remaining in overtime to win Saturday’s Pocono Green 225.
The is Briscoe’s fourth in the NASCAR Xfinity Series this season, including two of the last three, and sixth of his career.
Chastain ended up second and came away with the final $100,000 Dash 4 Cash bonus of the season. Chastain claimed two of the four bonuses this season.
“We were really not that good at the beginning and we didn’t have the speed I really anticipated us to have here,” Briscoe said. “The guys kept working on it and getting it better and better. We had the lead there after I sped on pit road – I was little worried but a lot of the good cars got torn up and it made it a little easier to get back through the field.
“Racing Ross was pretty fun. He’s also one of the hardest guys to race against and pass.”
Asked how much concern he had when Chastain quickly grabbed the lead on the final restart, Briscoe said, “There was a ton of concern. I was really tight and I felt if I went to the bottom (lane) I’d get too tight on exit.
“When I was catching Ross, I knew his trouble was in (Turn 2), he was just so loose. I just tried to use that to my advantage. It was fun. We raced clean the whole time. It’s fun when you can do that.”
Jeremy Clements finished third, Myatt Snider was fourth and Michael Annett completed the top-five.
The Xfinity Series returns to action next Saturday for its first-ever race on the Indianapolis Motor Speedway road course, part of a NASCAR-IndyCar Series doubleheader weekend.
