McCarty, a Kingsport driver in the No. 5 Ford, drove into the third turn in the middle of Broyles’ car on the low side and Maupin’s on the high side.
In a classic short-track maneuver, McCarty nudged Maupin’s No. 0 Chevrolet up the track and he then cleared Broyles racing off the fourth turn to put his car out front.
The move also allowed Nik Williams and Danny O’Quinn to get by the duo. Williams, a 21-year old driver from Chuckey, finished second in the No. 32 Chevrolet to wrap up his first Kingsport Speedway championship and the Tennessee state championship for the NASCAR Whelen All-American Series.
O’Quinn, a former NASCAR Nationwide Series (now Xfinity Series) rookie of the year from Coeburn, Virginia, finished third after an intense battle with Johnson City driver Zeke Shell throughout the second half of the race.
Maupin finished fourth and Shell wound up fifth in the final rundown.
Shell, the 2018 track champion, looked like he might have a fourth win of the season locked up when the race was red flagged for a rain storm on lap 31. It could have been called an official race at that point, but speedway officials decided to dry the track and restart the race.
It meant a wild second half of the 60-lap feature on the 3/8-mile concrete oval. McCarty raced Shell side-by-side for the top position for three laps before McCarty emerged as the leader.
O’Quinn spun out Shell on lap 49. While under caution, Shell pulled alongside of O'Quinn on the backstretch to let him know he wasn't happy with the move. Williams had his own problems, spinning out on lap 51 with a flat right-front tire. His crew got it fixed and Williams raced his way back to the runner-up finish.
Shell finished second in the final Late Model championship standings, ahead of Bluff City’s Wayne Hale. Kingsport drivers Derek Lane and Rick Pannell rounded out the top five.
Kevin Canter of Abingdon capped off his Mod 4 championship by driving his black No. 3 Ford to a 17th win in 18 starts. For the second straight week, Chris Amburgey posted a runner-up finish.
The rest of the top five remained the same as the previous week with third-place Billy Duty followed by Hershell Robinette and Jessie Amburgey.
Royce Peters of Kingsport captured his third win of the season in the Mod Street division. Peters in the red No. 42 Camaro edged Abingdon driver Kevin Wolfe for the race win. With his second-place run, Wolfe clinched the track championship. Colby Higgins, Luke Fox and Richard Adkins took the third through fifth positions.
Keith Helton of Kingpsort finished off his track championship season with style with his 12th win of the season in the Pure 4 division.
Billy Byington was second, followed by Josh Detwiler in third. However, Detwiler was disqualified in post-race tech, which moved Kenny Absher, William Hale and Todd Duff up to the third through fifth positions.
Tony Dockery of Dungannon, Va., completed his strong late-season run in the Pure Street division with his fifth win in the last six races. Doug Austin wrapped up the track title with his runner-up finish. Jay Swecker, Kevin Darnell and Jeremy Darughn rounded out the top five.
