If you’re a fan of race strategy, the Children’s of Alabama Indy GP was a thrilling affair as a battle between two- and three-stoppers played out for 90 laps on Sunday, and when it was over, Scott McLaughlin won round four of the NTT IndyCar Series season in front of a large and enthusiastic crowd.

The only caution of the day was triggered on lap 38 to retrieve the stranded No. 51 Dale Coyne Racing with Rick Ware Racing Honda driven by Sting Ray Robb. The series kept the pits open as the three-stop contingent dove in for tires and fuel while those on two-stops needed to stay out to make their strategy work. The timing didn’t necessarily harm those on two-stops, but it made life a bit easier for those on three.

The New Zealander’s victory came at the expense of polesitter Romain Grosjean—a bridesmaid once again—after the Swiss-born Frenchman led the majority of the race with his two-stop plan in the No. 28 Andretti Autosport Honda. But he succumbed to the pressure applied by the three-stopping McLaughlin late in the contest as he locked a brake and slid wide in Turn 5 on lap 72.

“It hurts,” Grosjean admitted. “The three-stop never wins in Barber, (except) today. We had an incredible car, drove really well; gave it 100 percent, but we got unlucky with that yellow. I gave it all. Congrats to Scott. He deserves to win. We got good points. Our day will come.”

Out of push-to-pass to rectify the error and hold off McLaughlin while powering out of the corner, McLaughlin fired his No. 3 Chevy down the inside of Grosjean on the run to Turn 6 and captured a lead he never surrendered.

“The team advanced me to victory lane,” McLaughlin said. “We had great fuel (mileage). I’m really pumped about it. I’m glad to get a win here. We had a hell of a strategy here today.”

Penske’s Will Power secured third, his first podium of the season, as his team’s gamble to start the race on the faster but less durable Firestone alternate tires paid off with a 1-3 finish; Josef Newgarden, the third member of the Penske trio, had an array of challenges that left him down in 15th.
