lap later for a multi-car crash in turn 2, before the race restarted on lap 77. Kenseth maintained the lead of the race, for a good portion of the race; he was not headed until Joey Logano took the lead on lap 104. The caution flew for the third time on lap 125 for a multi-car wreck on the backstretch that began when Brian Vickers got into Kyle Larson, and then spun into Aric Almirola. Clint Bowyer then ran into Kyle Busch, sending Busch spinning into the inside wall. Denny Hamlin took the lead during the caution period, and held the lead as the race restarted on lap 137.
