On Lap 51, with 14 minutes remaining in the race, Bowman passes Hand on Lake Shore Drive where it joins East Roosevelt Road (Turn 4), and with 12 minutes remaining, Josh Berry crashes into the tire barriers on Lake Shore Drive to bring out the safety car.

The Toyotas on slicks were faster, but with a minute and a half remaining, Ricky Stenhouse, Jr. collides with Martin Truex, Jr. (both on rain tires), making contact with Christopher Bell on Balbo Drive.

Reddick puts right-side tires on wet sections of at Roosevelt Road (Turn 4), making contact with the inside barrier, and then left side tires on wet sections in Turn 5 on the exit of Columbus Drive, making contact with the outside barriers, ending his efforts to catch Bowman.
