Final practice speeds: Kurt Busch tops the charts at Martinsville

The familiar suspects topped the speed charts in Saturday’s final NASCAR Sprint Cup Series practice session at Martinsville Speedway.

Defending race winner Kurt Busch was fastest in the 50-minute session, leading a charge of Chevrolets that included Jimmie Johnson, Jeff Gordon, Ryan Newman and Kasey Kahne in the top six.

Joe Gibbs Racing’s Denny Hamlin was fourth-fastest after leading the first session of the day. Pole sitter Joey Logano was seventh-fastest in the session, while Kevin Harvick, Carl Edwards and Greg Biffle rounded out the top 10.

While Biffle was 10th-fastest, his No. 16 Roush Fenway Racing Ford went for a spin halfway through the session and made slight contact with the outside wall. Able to drive away from the incident, the car had slight damage to the left rear of the car.

Michael Waltrip Racing’s Clint Bowyer struggled with the handling of the No. 15 Toyota during final practice, running 43rd throughout much of the session. In the final 10 minutes, Bowyer was able to make some gains but was only able to climb to 35th fastest.

"It’s pretty unbelievable," Bowyer said over the radio at the end of the session. "It’s too loose, it’s sheers, it’s tight in the middle, it’s loose."

The 50-minute session featured a lot of hard racing and a few run-ins on the track, including a tense moment in the close minutes between Austin Dillon and Danica Patrick.

However, Dillon told FOXSports.com the incident was simply because he got loose under her No. 10 Stewart-Haas Racing Chevrolet.

"It’s just a lot of cars trying to get their laps in at the end of practice," he said. "Not much space out there."

Rookie Brett Moffitt ran the most laps of the session, 74.

Edwards had the best 10-consecutive-lap average, followed by Busch, Hamlin, Gordon and Kahne.
