 Last night's Grant Park 165 NASCAR Chicago Street Race for the Cup Series was cut short due to darkness following lengthy delays due to multiple heavy rain showers earlier in the afternoon, concluding at lap 58 of the scheduled 75. At the finish, it was Hendrick Motorsports driver Alex Bowman at the front of the field to pick up his first win of the season, and doing so on wet weather tires on a fast-drying surface over the closing laps.
