McLaughlin topped the qualifying session around the 1.25-mile oval, which was delayed by rain yesterday, with a two-lap average of 49.1936s, a speed of 182.951mph.
But before qualifying, IndyCar officials announced nine-position starting grid penalties for McLaughlin, Alex Palou, Scott Dixon and Takuma Sato (Chip Ganassi Racing), Kyle Kirkwood (Andretti Autosport) and Agustin Canapino (Juncos Hollinger Racing) for unapproved engine changes since the last round on the Indianapolis Motor Speedway road course.
