He is only the seventh driver in Cup Series history to win on his debut, and the first since Johnny Rutherford in 1963 at Daytona.NASCAR Cup Series Grant Park 220Pole sitter, Denny Hamlin led the field to the green light on Sunday. On the opening lap, Tyler Reddick overtook Hamlin for the lead and established himself as a dominant race car. When Hamlin slipped into turn two and slammed the tire barrier on the second lap, his chances of winning were all but over. Soon after, Christopher Bell passed Reddick for the lead, setting up a close race for first place with Van Gisbergen. Front-runners Bell, Reddick, Larson, Gisbergen, Suárez and others were caught behind more than a dozen drivers who had chosen not to pit when they should have, allowing Justin Haley to take the lead. With around 10 laps to go, Van Gisbergen slowly got up to Haley and was ready to pass him when Martin Truex Jr. stopped in the turn-one tire barrier, bringing out another yellow. When the race resumed, Shane Van Gisbergen took the lead and created a good lead. After Bubba Wallace and Ricky Stenhouse Jr. crashed, the race was thrown into overtime, but Van Gisbergen was unfazed and raced away with his maiden victory.
