Logano beat Busch to the finish line by .034 seconds to win his second NNS race of the season and the 11th of his career.
Defending series champion Ricky Stenhouse Jr.ran third and took over the points lead from Elliott Sadler. Cole Whitt came home fourth, followed by his JR Motorsports teammate and bossDaleEarnhardt Jr.
Danica Patrick finished 13th, but after the checkered flag, she exacted revenge onSam Hornish Jr. for an earlier slight, knocking Hornish into the outside wall.
The race was red-flagged for a nine-car wreck that interrupted the first attempt at a green-white-checkered-flag finish on Lap 117. Eric McClure got the worst of the collision, taking a jarring hit against the SAFER barrier on the inside of the backstretch approaching Turn 3.
McClure was awake and talking to safety workers after the crash but was airlifted to UAB Medical Center in Birmingham to receive treatment for unspecified injuries.
After a stoppage of 19 minutes, the race resumed with the second attempt at a green-white-checker finish.
The wild wreck on Lap 117 was emblematic of an action-filled race.
Busch was charging from the back of the field after serving a penalty for dragging a fuel can from his pit stall under caution for Johanna Long's blown engine on Lap 22.
Dillon's car, however, sustained only cosmetic damage, and the reigning Camping World Truck Series champion soon worked his way back to the front of the field. His day ended when he was involved in the Lap 117 melee, leaving him to finish 17th.
Earnhardt had led 19 laps before a multicar wreck on the frontstretch slowed the action for the third time moments after the field had completed Lap 62. Brad Sweet spun off the front bumper of Mike Wallace's Chevrolet and slammed nose-first into the outside wall.
Josh Richards' spin on Lap 81 caused the fourth caution, providing the opportunity for fuel stops inside the window to the finish.
