Pato O’Ward, ran fourth in the early stages of the race despite running on Firestone’s harder primary tire, and was up to third for the race’s single restart, when he tried and failed to put a move on Will Power’s Team Penske-Chevrolet at Turn 1. He dived down the inside of the 2014 champion at the right-hander, and Power made as much room as possible for him, but was still struck by the AMSP car. Power then had the inside line for the left-hand part of the chicane and retained his second place, while O’Ward lost momentum.
Scott Dixon, who had gotten past the dueling Alexander Rossi and Josef Newgarden in the first part of the chicane thus had a run on O’Ward out of Turn 3, so on the run down to Turn 4 the Mexican ace moved right to block the charging Ganassi car. That earned him a penalty, whereby he had to cede his third place to Dixon.
