Five key moments in Sunday's race:
LAP 1 – Kurt Busch, wasting no time, dives below pole-winner Dale Earnhardt Jr. and leads the first of his record 175 laps.
LAP 123 – Dale Earnhardt Jr., fighting an ill-handling car, spins without hitting the wall. He makes three pit stops under caution to replace his left-front shock and remains on the lead lap.
LAP 153 – Busch, who restarted eighth on Lap 143, needs only 10 laps to pass Earnhardt Jr. for the lead.
LAP 183 – A five-car wreck in Turn 2 gives Earnhardt Jr. one more chance to get close to Busch as the field is bunched up under caution.
LAP 190 – Busch leads his 165th lap, setting a NASCAR record at Pocono Raceway.
