Will Power led at the halfway point in the Chevrolet Dual in Detroit Race 1, but Marco Andretti is gambling on strategy to have a shot to win the race.
Andretti pitted just after the halfway mark to move from dry tires onto rain ones; he had led the most laps in the opening half of the race.
Prior to that, the top 10 at halfway was: Power, Andretti, Carlos Munoz, Simon Pagenaud, Scott Dixon, Helio Castroneves, Jack Hawksworth, Luca Filippi, Josef Newgarden and Stefano Coletti.
Polesitter Power led the following green flag stops by the leaders immediately following a restart. At one point, the defending champion lost at least five positions during a caution for a Lap 12 Charlie Kimball crash.
Power lost the lead on Lap 3 to Takuma Sato right before the second caution of the race (the race began under green-yellow conditions).
Rodolfo Gonzalez spun his No. 18 Honda coming out of Turn 2 and stalled against the outside wall. Debris from Gonzalez would bring out another caution on Lap 26.
The race’s biggest shake up so far occurred on Lap 6 with a four-car incident in Turn 1 involving Graham Rahal, Tony Kanaan, Stefano Coletti and James Jakes. Rahal is out of the race, but Kanaan has returned to the track and is running 21st, 13 laps down.
The fourth caution, on Lap 21, was for debris from Takuma Sato’s car, which made contact with Josef Newgarden and Sato’s left-front wing.
There have been 7 cautions for 18 laps so far.
