NASCAR’s first in-season tournament hasn’t made much of an impression on its drivers so far. Ty Gibbs said Sunday he didn’t know who his second-round opponent was until after the Cup Series race.

Temperatures cooled down for Sunday afternoon's main event, the NASCAR Cup Series Grant Park 165. There was a chance for rain in the forecast — something that's caused the main race to be shortened in each of the first two Chicago Street Race events.

Before the street race, there's the race behind the scenes to get the track, grandstands, cars, and other preparations ready for the main event.
