Only three drivers led laps on Sunday with Busch out front for 187, points leader and Chicagoland victor Martin Truex Jr. led 112 en route to a fifth-place finish. This marked Truex's 59th Playoff bonus point. Jones (fifth) was the lone non-playoff driver to earn Stage 2 points.
It was a record-setting hot day in New Hampshire.
A dominant Truex was leading when he was swept into a multi-car accident on the final lap of the second stage. The spinning 4 auto created a cloud of thick smoke, and it was unable to see through. Kurt Busch, Dillon and Hamlin were also gathered up in the mess, but it was Kurt Busch and Harvick who got the worst of it, as the wreck ended both their afternoons.
"All in all a great day", Busch said.
Chelsea: Alvaro Morata Nets Slick Hat-Trick As Blues Cruise Past Stoke
It seemed nothing would go Stoke's way and Morata finished any thoughts of a comeback with 13 minutes remaining. The two teams match up next weekend in the first heavyweight bout of the season.
After assuming the lead on lap 150, Kyle Busch led nearly all of the remaining laps.
With this win, Kyle Busch has secured his spot in Round 2 of the Playoffs. The remaining drivers in the top-10 were all playoff contenders: Blaney, Kenseth, Keselowski, Johnson, Hamlin and Harvick.
Busch, who began the ISM Connect 300 from pole, held off Kyle Larson and Matt Kenseth after a caution reset the field with 23 laps to go.
