Ganassi’s Scott Dixon took his second win of the year and the IndyCar Series points lead in a frankly ridiculous Detroit street race that featured eight caution stoppages and rain shaking up the order.

At times it felt like we’d never finish the race - 47 of 100 laps were under caution, such was the propensity of incidents at Turn 3, the first corner after the restart here - but another fuel gamble from Dixon allowed him to leap to the front, albeit under late pressure (in different ways) from a pair of intervening Andretti drivers in Colton Herta and Marcus Ericsson.

Rain around the lap 33 mark gave drivers a decision to make and 18 pitted for wet tyres as it went yellow, but by the time the race went green the track was dry and those drivers had to pit again for dry tyres.

That, plus the number of cautions, meant a mixed-up order. A total of 12 penalties were also  dished out, amid six different leaders and a wild finale.

How did Dixon win?

Dixon started fifth and on the preferable hard tyre, and avoided taking the gamble of wet tyres - which had been made even more tempting by a caution brought about by Scott McLaughlin crashing at Turn 1.
