FORT WORTH, Texas — Helio Castroneves raced to his first IndyCar victory of the season, leading the final 132 laps of the Firestone 550 on Saturday for his fourth career victory at Texas Motor Speedway.
Castroneves also won at the 1½-mile, high-banked track in 2004, 2006 and 2009.
"Texas is awesome. I love this place," Castroneves said after celebrating by climbing the frontstretch fence.
Former series champion Sam Hornish Jr. was the only other three-time IndyCar winner at Texas, and his last came for Roger Penske, who now has eight victories at the track that has hosted 25 IndyCar races.
Ryan Hunter-Reay of Andretti Motorsports finished second, more than 5 seconds back.
With six other top-10 finishes in the first seven races, Castroneves entered the night tied with Marco Andretti for the season points lead. Andretti, who led the first 53 laps after starting on the front row, finished fifth. He dropped to second, 22 points behind Castroneves.
NEWTON, Iowa — The Nationwide Series race at Iowa Speedway was postponed Saturday night after rain began falling about 40 minutes before the scheduled start.
Workers were nearly finished drying the track when it started to pour again, forcing officials to push the DuPont Pioneer 250 to 11 a.m. today (ESPN2).
Austin Dillon won the pole for the third week in a row, and he will start alongside Sam Hornish Jr. Dillon became the sixth Nationwide driver to win three consecutive poles. With one more at Michigan next week, he will break the series record.
The postponement ensures that today's field will be made up solely of Nationwide regulars. Cup driver Joey Logano, racing today at Pocono in Pennsylvania, will be replaced by teammate Ryan Blaney.
Formula One: Sebastian Vettel hopes to finally convert a spot at the front of the Canadian Grand Prix field into a place on the top of its podium.
The points leader earned his third straight pole at Montreal's Circuit Gilles Villeneuve, posting the fastest lap in a rain-shortened qualifying session. In two previous starts from the front of the 2.71-mile course, Vettel has finished second and fourth.
Vettel has a 21-point lead in the standings over Lotus' Kimi Raikkonen. Lewis Hamilton, fourth in points, will start next to Vettel for the second year in a row here.
Trucks: NASCAR has another winner named Burton. Jeb Burton, the 20-year-old son of 2002 Daytona 500 winner Ward and nephew of current Sprint Cup driver Jeff, raced to his first truck series victory late Friday at Texas Motor Speedway. "I've been telling everybody once we get one, they're going to start stacking up," said Jeb Burton, who led the final 24 laps of the WinStar World Casino 400, holding off Ty Dillon by 0.139 seconds to become the youngest driver to win a truck race at Texas.
