After seeing two of his teammates get involved in an incident early on in practice, Kevin Harvick posted a lap at 165.145 mph to lead opening practice.  With rain in the forecast the No. 4 car would sit on pole if qualifying were to get postponed.

The last time the Cup Series raced at Dover it was Harvick that dominated the race leading a career-high 355 laps, racing his way into the next round of the Chase. If this were qualifying, the No. 4 machine would have set a new track record.

Dale Earnhardt, Jr. ran the second quickest lap at 164.707 mph. With just six laps run on the racetrack, the No. 88 car was focused primarily on qualifying runs with rain on the horizon.

A pair of Joe Gibbs Racing teammates slotted themselves in third and fourth. Kyle Busch ran at 164.489 mph and Carl Edwards at 164.144 mph. Ricky Stenhouse, Jr. rounded out the top five at 163.815 mph.

Outside of the first five minutes with a wreck involving the Stewart-Haas Racing teammates of Danica Patrick and Tony Stewart, along with Jamie McMurray the practice went green. All three of those drivers got back out on track in their backup cars, with the No 1 quickest at 24th.

Chase Elliott was the fastest rookie driver in 13th, just under three tenths of a second behind the lap that Harvick put down. His teammate, and 10-time Dover winner, Jimmie Johnson, was 21at on the chart.

If the rain stats away from the racetrack, ualifying is slated fto begin at 3:45 p.m.
