LEBANON, Tenn. — Ross Chastain held off Martin Truex Jr. and won the Ally 400 at Nashville Superspeedway on Sunday night, his third career NASCAR Cup Series victory.

This was Chastain’s first win since Talladega in April 2022, and he drove his Trackhouse Racing Chevrolet to the team’s first victory this year at its home track. Chastain had started on the pole for the first time in his career.

Chastain entered fourth in the season points race and wound up leading a race-high 100 laps at the 1.33-mile, D-shaped concrete oval. That included the final 34 laps as the 30-year-old had to weave by some slower traffic to hold off Truex by 0.789 seconds.

The driver known as “Melon Man” celebrated clinching a playoff berth with a burnout before smashing a watermelon onto the start-finish line.

Truex led 50 laps as the season points leader tried to string together back-to-back wins. He won at Sonoma going into NASCAR’s lone break in the 38-race season.

Truex finished ahead of Joe Gibbs Racing teammate Denny Hamlin, both in Toyotas. Chase Elliott was fourth and Hendrick Motorsports teammate Kyle Larson was fifth.

Tyler Reddick started beside Chastain on the front row and won the first stage.

As they began the second stage, Truex went three-wide at the front with Chastain and William Byron for some thrilling racing on a track known for having boring competition for years after opening in 2001.

The Xfinity Series race on Saturday was chaotic, with cautions starting on the opening lap.

The second caution on Sunday didn’t come until lap 138 when Reddick lost his right rear tire as he tried to steer his Toyota onto pit road just after having pitted. His car got loose, and he spun into the grass with the tire coming off at the entrance to pit road.

HARD CRASH

The third caution came on lap 146 on the restart on the frontstretch as Ryan Blaney crashed head-on into an interior wall after being tapped from behind by Kyle Busch with Alex Bowman also involved. Blaney walked out of the infield care center after what he called the hardest hit of his life.

Blaney said he checked up on the restart and got hit from behind, then he couldn’t get his Ford straightened up after hitting the grass. He called it “pretty ridiculous” there was no SAFER barrier on the infield wall.

“Stinks going home early,” Blaney said.

REUNITED

Stewart-Haas Racing made a flurry of crew chief changes Tuesday before this weekend at Nashville, and Chase Briscoe was reunited with Richard Boswell, who guided him to eight Xfinity Series wins between 2018 and 2020. Boswell had been crew chief for SHR’s No. 98 Xfinity team with Riley Herbst.

Briscoe finished 31st.

NO. 200

Bubba Wallace made his 200th Cup Series start, looking to add to his two career wins and 15 top fives. He started ninth in the No. 23 Toyota for 23XI Racing and finished 15th.
