DETROIT (AP) — Scott Dixon made some savvy decisions, choosing not to pit for rain tires early and calculating that he would have enough fuel to finish, that paid off at the Detroit Grand Prix.

Dixon also had some good fortune on his side.

“Some of it today was a little bit of luck,” he acknowledged.

Dixon won a record fourth Detroit Grand Prix, outlasting the competition in a caution-filled race on Sunday to become the first IndyCar driver with two victories this season. The six-time IndyCar Series champion won his 58th career race, trailing only A.J. Foyt’s total of 67 in the series.

The New Zealand racer was responsible for the fifth and final lead change on Lap 66, and held off a late charge from Marcus Ericsson to break a tie in the Detroit Grand Prix record books with Will Power and Helio Castroneves.

The Chip Ganassi Racing driver finished nearly a second ahead of Ericsson and was followed by Marcus Armstrong, Kyle Kirkwood and Alexander Rossi thanks to strategy that also served him well during his win at Long Beach in April.
