Kyle Larson wins Brickyard 400 in controversial fashion

Kyle Larson won the Brickyard 400 on Sunday, but it didn't come without a little bit of controversy. 

With Ryan Blaney and Brad Keselowski lined up for an overtime restart, Keselowski's Ford Mustang, which was low on gas, started sputtering, forcing Keselowski to take his car down pit road. Larson, who was originally lined up third suddenly found himself on the front row. 

On restarts, NASCAR designates the race leader as the "control car" — meaning the car that is supposed to accelerate first in the restart zone. With Keselowski being the leader before coming to pit road, Blaney only had a matter of seconds to realize that he was now the control car. 

On what turned out to be the race's second-to-last restart, Larson appeared to accelerate early and ended up grabbing the lead before the caution came out in turn one. On the next restart, Larson pulled away from Blaney, who had to yield the second spot to Tyler Reddick.
