One of the prizes eluding Scott Dixon in his illustrious Indy car career was a win at Road America in Wisconsin.
The New Zealander took care of that by winning today's race at the picturesque permanent road course.
Dixon crossed the finish line half a second ahead of Josef Newgarden to collect the 41st win of his career, moving the four-time IndyCar Series champion within one victory of tying Michael Andretti for third on the all-time list.
Dixon's first victory of the 2017 season also allowed him to stretch his points lead to 34 points over last year's season champion, Simon Pagenaud.
It also makes Dixon the eighth different driver to win in 10 races this season, continuing the series' ultra-competitive trend.
Dixon led 24 of the last 25 laps to win for the first time at Road America in his fourth start on the track named by most IndyCar Series drivers as their favourite road course. Dixon has now won on 11 of the 16 circuits on this year's schedule.
Dixon, with eight top-six finishes in the first 10 races, has earned 379 points. Pagenaud is second with 345, Road America pole sitter Castroneves third at 342, Indianapolis 500 winner Takuma Sato fourth with 323 and Newgarden fifth at 318.
The next IndyCar Series race is the Iowa in a fortnight.
