Storms washed out qualifying at Kentucky Speedway on Friday, putting Kevin Harvick on the pole for Saturday night's Sprint Cup Series race based on owner points.
Severe weather moved over the track near midday and shortened practice to around 30 minutes. The hope was for weather to hold off for track drying and allow practice session to be concluded by late afternoon.
In the meantime, Harvick will lead the field to green in the No. 4 Chevy alongside Brad Keselowski in the No. 2 Ford.
The rest of the top 10: Kurt Busch (Chevy); Joey Logano (Ford); Joe Gibbs Racing teammates Carl Edwards and Kyle Busch in Toyotas; Martin Truex Jr. (Toyota); rookie Chase Elliott (Chevy); Jimmie Johnson (Chevy) and Denny Hamlin (Toyota).
