Marcus Ericsson turned the quickest lap in the final warm-up session for the GMR Grand Prix. Ericsson edged Callum Ilott by 0.113 seconds. Pole sitter Will Power was ninth and Alex Palou, who starts second, was eighth.

Six Honda cars were in the top 10 in the thirty -minute practice, which ran green the entire way.

Reminder- the green flag time has been moved up to 3:07 pm Eastern to avoid as much of the thunderstorms as possible. The documentary The Club will still air at 2 pm on NBC.

The chance of rain may cause some teams to rethink their starting tire choices.

Notes

Caesar’s Sportsbook has taken over the spot where the memorabilia show used to be. It is a betting parlor. I’m not sure if I like this idea.

The race will go on if there is only rain. Lightning will cause a red flag. I believe a halt for lightning will be at least thirty minutes. 44 laps will be an official race.
