Ty Gibbs holds on to win NASCAR Cup Series race at Iowa Speedway

NEWTON, Iowa (AP) — Ty Gibbs didn’t question his crew chief’s final pit call.

“I can’t do anything about it, so you just run with it,” Gibbs said.

Gibbs used late pit strategy and held off Joe Gibbs Racing teammate Christopher Bell over the final 20 laps to win the NASCAR Cup Series race Sunday at Iowa Speedway.

Gibbs — the 23-year-old grandson of former NFL coaching great and NASCAR team owner Joe Gibbs — won by 0.253 seconds over Bell for his second victory of the season and his career.

Gibbs and Bell each pitted with 60 laps remaining in the 350-lap race, but while Bell took four tires, Gibbs just went with two right-side tires, and came out ahead. And when leader Ross Chastain pitted on Lap 330, Gibbs took over the top spot and fought off a late charge by Bell.

Tyler Allen, Gibbs’ crew chief, thought taking two tires was the only chance to get ahead of Bell in that final pit cycle.

“We knew after practice the left sides weren’t wearing much and they tended to refire OK,” Allen said. “So in terms of coming into the race, it was definitely a viable option.”

Gibbs liked the aggressive call.

“I think in the position with our points situation, for sure,” he said.

Gibbs, who picked up his first career win April 12 at Bristol, came into the race ranked fourth in the season standings, and moved into second — 103 points behind JGR teammate Denny Hamlin.
