Hendrick Motorsport driver Byron made a timely charge to the front of the field following the final round of green flag pit stops.
After a massive late wreck, Byron bolted to the lead on a restart with four of the 200 laps remaining. Approaching the white flag to signal one lap remaining, Byron moved to block the oncoming charge of Ross Chastain's Trackhouse Racing Chevrolet, who then clipped the Penske Ford of Austin Cindric.
That triggered another multi-car wreck and as Cindric's car slid back up the track, NASCAR made the decision to throw the caution. Per NASCAR rules, a caution flag on the final lap means the field is frozen and the race is over.
Bowman, who had pushed Chastain into contention, continued his momentum to pull alongside his team-mate Byron as the caution flag few.
After much speculation, NASCAR posted the following explanation on social media:
Added Mike Forde, the Managing Director of Racing Communications: "NASCAR uses all available resources at the end.
"Here is the aerial photo at the time of caution. You can also see the #2 car [Cindric] coming back up the racetrack. That's why the yellow was called.
"[We] had hoped it would have stayed down on the apron like the #1 [Chastain] did and end under green."
Bowman never questioned NASCAR's decision and was "proud" of Byron, saying: "They deserved it there at the end. They did all the right things, and I feel like we did too there at the end.
"Had to go up and block the top lane and that just killed the middle for a bit. We got the middle back rolling and then they all started crashing."
Jeff Gordon knows a thing or two about being a superstar in the NASCAR Cup Series and sees another quickly blazing a path in the #24 Chevrolet he made famous.
Gordon, who won four Cup titles and 93 races with Hendrick Motorsports, is now vice chairman of the organisation and was already impressed with Byron's development aboard the #24 car.
