Joliet, Ill. — Martin Truex Jr. went from a completely unraveled tire that left him a lap down to the NASCAR Chase for the Sprint Cup championship lead for the first time in his career.

He can thank a late caution in what has been an emotional year for the small-team driver.

Truex shot to the front after a late re-start and pulled away to give Furniture Row Racing a NASCAR Sprint Cup playoff-opening victory Sunday at Chicagoland Speedway.

“I’ve had a lot of practice at it,” Truex said about the on-track obstacles. “I think my approach really changed two years ago when (girlfriend) Sherry got diagnosed with cancer. My approach to all those things changed and made me a better driver.”

NASCAR announced after the race that Truex’s No. 78 Toyota failed the laser inspection, but the infraction was not at the level of negating the victory for Chase qualification purposes. Truex is expected to receive a point penalty this week.

Rookie Chase Elliott appeared on his way to an easy win until Michael McDowell blew a tire and spun out to bring a caution with five laps left.

Elliott and Truex came in to pit for tires, with some non-Chase drivers Ryan Blaney and Kasey Kahne and Chase contender Carl Edwards staying on the track.

Truex re-started fourth and Elliott fifth, and Truex quickly got to the front and held off Joey Logano on the final lap for his third victory of the season. Truex is guaranteed to move on when the Chase field is cut from 16 to 12 in two weeks.

Truex, whose team gets technical support from Joe Gibbs Racing, made the last four in the 2015 Chase. His 2016 season started with near miss at the Daytona 500 and a Coca-Cola 600 win, while Sherry Pollex has battled ovarian cancer. She’s now in remission.

“You have to understand, this isn’t the end of the world.” Truex said of racing setbacks. “We can overcome it. That’s what we did today.”

Elliott, a rookie, finished third, followed by Blaney and Chase driver Brad Keselowski of Rochester Hills, who sits second in points.

“It’s not yours until it’s over,” the 20-year-old Elliott said. “That’s part of life, man. You’re not dumb. We’ve all watched this stuff long enough to know these races don’t go green that long.”

Truex led early in the race only to have his tire come completely unraveled. It led to an unscheduled stop that left him a lap down in the 400-mile race.

“The hard compound came off it,” Cole Pearn, Truex’s crew chief, said. “I guess (Goodyear) saw a couple other tires and came down and told us a certain sequence number had an issue.”

Truex had no other tire issues on the 1.5-mile oval and outraced Kevin Harvick, who also got into early trouble, to be in position for the free pass to the lead lap on the next caution.

Jimmie Johnson dominated the middle of the race, leading 118 laps, until Elliott got by him on lap 176 of 267.

IndyCar

At Sonoma, California, Simon Pagenaud gave Roger Penske an IndyCar championship to help celebrate the 50th anniversary of the one of the most storied organization in motorsports.

The Frenchman won his first career IndyCar title in his sophomore season driving for Penske. He did it in dominating fashion by winning the season finale Sunday at Sonoma Raceway, where he needed only a smooth finish to put a wrap on this breakthrough season.

Pagenaud entered the weekend 43 points ahead of teammate Will Power as the Penske drivers were the only two mathematically eligible to win the championship. But Pagenaud won the pole to earn another point, led the most laps and won a race that was worth double points in the standings.

It was a moot point, though: Power had mechanical issues 38 laps into the race that sealed the outcome.

Formula One

Nico Rosberg hung on for the narrowest Formula One victory for six years to win the Singapore Grand Prix on Sunday, celebrating his 200th career start in perfect style as he reclaimed the championship lead from his Mercedes teammate Lewis Hamilton.

Rosberg held on to beat a fast-finishing Daniel Ricciardo of Red Bull by just 0.488 of a second. Hamilton took third place.

Rosberg’s third successive win, and first in Singapore, took him to the top of the drivers’ championship with six races left.
