British-born US driver Charlie Kimball claimed his first IndyCar win on Sunday, continuing Chip Ganassi's recent dominance in the American open-wheel racing series.
In a race that ran caution-free at the Mid-Ohio Sports Car Course, Kimball passed French driver Simon Pagenaud and took the lead for good with 18 of 90 laps remaining.
He beat Pagenaud to the finish line by 5.5 seconds to notch his first win in his 45th start.
Ganassi, meanwhile, notched their fourth straight victory of the season. New Zealand's Scott Dixon had won the previous three races for Ganassi, one at Pocono and two at Toronto.
Kimball became the fourth first-time winner in the series this year, joining Canada's James Hinchcliffe, Japan's Takuma Sato and Pagenaud.
Scotland's Dario Franchitti, another Ganassi driver, finished third. Australia's Will Power and reigning series champion Ryan Hunter-Reay rounded out the top five.
Brazil's Helio Castroneves finished 14th, but maintains a 31-point lead over Dixon atop the series standings.
