While Shane van Gisbergen was once again the driver to beat on Sunday, his closest competition never got a fair shot in the end due to some mechanical gremlins.
Michael McDowell started from the outside of the front row at the Chicago Street Course and took the lead from SVG on the opening lap. He went on to win Stage 1 and appeared to be a real threat for the win. The Spire Motorsports driver was also facing a two-year winless streak and hoped to put that behind him on Sunday.
Unfortunately, after leading the most laps (31), a stuck throttle forced him to give up the lead and head to the garage for repairs. He returned to the race over 20 laps down, finishing a disappointing 32nd. Meanwhile, van Gisbergen captured the checkered flag.

“The throttle cable just broke," said McDowell. "I don’t know what caused it or how it got to that spot, but that’s what happened. I feel like we had control of the race. I think it would have been a battle, no doubt. I felt like any time I could open a gap on SVG, I could.
"We were just working on our strategy. We knew we were going to one-stop it, so I was taking care of the tires and doing all the things I could. I was behind the pace car and the throttle stuck wide-open. Luckily, I got to the switches fast enough before I ran into something, and then a cable broke after that. It’s just a shame. We had a great No. 71 DePaul Chevrolet. We’ve got some good momentum heading into Sonoma next weekend.”
The good news for McDowell is that NASCAR heads to another road course next weekend with Sonoma, where he finished second just one year ago.
