Rahal completes sweep

Graham Rahal completed a doubleheader sweep in the Detroit Grand Prix on Sunday to become IndyCar’s first two-time winner this season. Rahal’s Honda-power car finished 1.17 seconds ahead of Josef Newgarden’s Chevrolet, a day after getting to the checkered flag six-plus seconds ahead of the competition. The Rahal Letterman Lanigan Racing driver pulled away for the victory after a single-file final restart with two laps to go in the 70-lap race on Belle Isle course. Rahal became the first to sweep in Detroit since it began hosting doubleheaders in 2013. He became the first to win two IndyCar races in a weekend since Scott Dixon pulled off the feat four years ago in Toronto. A red flag stopped the race for 18 minutes after 67 laps because Spencer Pigot’s car had a mechanical failure. The Ed Carpenter Racing driver got out of his smokefilled car after a yellow flag came out because James Hinchcliffe’s car stalled. On Saturday, Rahal, from New Albany, Ohio, became the first American to win in Detroit since Michael Andretti in 1996. He has six career victories, five in two-plus seasons. Will Power of Team Penske was third Sunday, giving Chevy a better showing than on Saturday when Honda swept the podium near General Motors’ world headquarters. Force tops in New England

Brittany Force won the NHRA New England Nationals in Epping, N.H., on Sunday for her first Top Fuel victory of the season and fourth overall. The daughter of Funny Car star John Force, she beat Antron Brown in the final with a 3.716-second pass at 328.62 mph. “We figured things out in Topeka [in the last event] and I felt like we had our team back so we knew our first win would be right around the corner for us,” Force said. “The key to it all is our team sticking together and not giving up, and it definitely paid dividends today.” Brown had a 3.728 at 327.98. Matt Hagan won in Funny Car, and Erica Enders topped the Pro Stock field. Hagan raced to his third victory of the season and 25th overall, beating Courtney Force — Brittany Force’s sister — with a 3.897 at 332.59 in a Dodge Charger. Enders won for the first time this season and 22nd time overall. She had a 6.534 at 213.16 in a Chevrolet Camaro to edge Tanner Gray.
