LOUDON, N.H. — Zackery King appeared to have New Hampshire Motor Speedway firmly under control. Then, in a matter of moments, a dominant afternoon became one of the biggest missed opportunities of his season. With only two races remaining before the AARN Cup Series Chase, King led a race-high 76 of 158 laps and spent much of Sunday looking like the driver who would leave Loudon with both a victory and the championship lead. Instead, a late-race spin and subsequent trouble knocked the No. 51 out of contention and opened the door for Coulter Clark, who capitalized on the opportunity to score his eighth victory of the season.

Clark started from the pole, led 25 laps and survived an eventful closing stretch to beat Joshua Stoudt by 0.901 seconds. Chris Romano finished third, Jordane Whyte fourth and current points leader Shawn Hughes completed the top five. The victory could not have come at a better time for Clark. Two races ago, an early accident at Indianapolis dealt a significant blow to his regular-season championship hopes.

He responded with a third at Richmond and now a victory at New Hampshire, bringing the No. 54 back within 32 points of the championship lead. Clark also completed the race without an incident and recorded the fastest lap of the afternoon at 29.397 seconds, earning four bonus points and an event-high 47 total points. For most of the race, however, the story appeared destined to be King. Starting fifth, King moved to the front and controlled nearly half the event.

His 76 laps led were more than three times Clark’s total, and the No. 51 collected bonus points for leading and leading the most laps. With Hughes starting 16th and Romano eighth, the opportunity was there for King to regain the championship lead he lost at Richmond. Instead, the race turned late. King spun during the closing portion of the event and became involved in additional trouble that ultimately left him eight laps behind.

He was credited with 13th place after completing 150 laps. What could have been a maximum-points afternoon became just 33 points. The damage was magnified by the fact that Hughes and Romano both survived a race filled with 11 cautions for 33 laps and finished inside the top five. King entered New Hampshire only two points behind Hughes.

He leaves eight behind. Hughes quietly did exactly what championship contenders need to do on difficult afternoons. The No. 75 started 16th but methodically climbed through the field, avoided the incidents around him and finished fifth. His 39-point afternoon increased his season total to 891, allowing him to retain the points lead with two races remaining.

King sits second at 883, while Romano is only another two points back at 881. That means just 10 points separate the top three drivers with two races left in the regular season. All three have already secured their places in the Chase. Now the fight between Hughes, King and Romano is about the regular-season championship and positioning themselves as strongly as possible before the postseason begins.

Romano took full advantage of King’s trouble. Starting eighth, the No. 44 stayed in contention throughout the afternoon and finished third, only 1.424 seconds behind Clark. The result was Romano’s 11th podium of the season and pulled him to within 10 points of Hughes. One mistake by any of the three leaders over the final two races could completely reshuffle the championship.

Whyte continued his late-season surge with another strong finish. After winning Richmond one week earlier, the No. 83 finished fourth at New Hampshire and now sits fifth in points with 818. Whyte has six victories this season and has increasingly looked like one of the strongest cars heading toward the Chase. W.

Casey Gross was another major factor Sunday. Gross led 55 laps, second only to King, and spent considerable time battling at the front. The No. 77 could not convert that speed into the victory, however, and eventually finished 11th, one lap down. It was a frustrating result considering how much of the race Gross spent near the front, but he still earned a bonus point for leading and remains sixth in the standings with 794 points.

Behind the leaders, the Chase bubble became considerably more uncomfortable for several drivers. Douglas Scalice entered New Hampshire eighth in points and looking to put additional distance between himself and the cut line. Instead, the No. 16 became involved in an accident and accumulated 16 incident points before eventually finishing 12th, five laps behind. Scalice collected only 32 points and now sits eighth with 777 points.

His advantage over the current cut line has shrunk to just 23 points. Kameron Combs suffered an even more damaging afternoon. The No. 15 completed only 115 laps before disconnecting and finished 17th. Combs remains seventh in the standings with 781 points, but he is now only 27 points above 10th.

Elijah Maupin is under even more pressure. Maupin finished seventh at New Hampshire and brought home a solid 37-point day, but he sits ninth with 760 points, only six ahead of Gregory Vadnais. Vadnais finished ninth and now occupies the 10th and final traditional transfer position with 754 points. That makes the lower portion of the Chase picture extremely tight with only two opportunities remaining.

Combs has 781. Scalice has 777. Maupin has 760. Vadnais has 754.

Just 27 points separate seventh from 10th. Corey Powell remains the first driver on the outside looking in. Powell finished 14th at New Hampshire and now trails Vadnais by 44 points. With two races remaining, the path is becoming increasingly difficult, but the amount of trouble seen Sunday demonstrated why nothing can yet be considered settled.

New Hampshire was a race where survival mattered almost as much as speed. Eleven cautions repeatedly interrupted the afternoon and produced 33 laps under yellow. Thadeeus Freel Jr. and Chris Winstone both saw their races end after only 36 laps. Combs failed to reach the final quarter of the race.

King went from controlling the event to finishing eight laps behind. Through all of it, Clark kept the No. 54 positioned to capitalize. Stoudt delivered an impressive runner-up performance after starting 11th, while Romano, Whyte and Hughes rounded out the top five. Joseph Essenberg finished sixth, followed by Maupin, Joe Konen, Vadnais and Charles Allen Jr. Clark’s victory gives him eight wins in 20 starts, along with 16 top-five finishes, 19 top-10s, 13 podiums and 825 laps led.

His 859 points leave him 32 behind Hughes, and while time is running short, the regular-season title has not completely escaped him. The championship standings leaving New Hampshire now have Hughes at 891, King at 883, Romano at 881 and Clark at 859. Whyte sits fifth at 818, followed by Gross at 794, Combs at 781, Scalice at 777, Maupin at 760 and Vadnais at 754. New Hampshire covered 158 laps and produced seven lead changes among four different leaders with a strength of field of 1,816.

But the numbers that matter most now are much smaller. Two races remain. Ten points separate the top three. Six points separate ninth from 10th.

Twenty-three points separate Scalice from the cut line after another costly afternoon. King leaves Loudon knowing he had an opportunity to take command of the championship and watched it disappear in a late-race spin. Clark leaves with the trophy and renewed life. Hughes remains atop the standings, while Romano is suddenly right on his heels.

The Chase is almost here. And after New Hampshire, very little about the final two races looks comfortable.
