Kyle Busch avoids disaster during practice run at Darlington


Darlington practice was not kind to Kyle Busch/

Rowdy's No. 18 Joe Gibbs Racing Toyota slid out during practice and avoided hitting the wall -- and still posted the fastest speed at 173.320 MPH.

This guy is clearly on a roll.

The other top five finishers -- Kevin Harvick's  No. 4 Stewart-Haas Racing Ford (173.070 mph); Jamie McMurray's No. 1 Chip Ganassi Racing Chevrolet (172.990 mph); Martin Truex Jr.'s No. 78 Furniture Row Racing Toyota (172.729 mph); and Denny Hamlin's No. 11 Joe Gibbs Racing Toyota (172.632 mph).
