Martin Truex Jr. topped the leaderboard in the final Monster Energy NASCAR Cup Series practice at Las Vegas Motor Speedway on Saturday, logging a lap at 188.613 mph in his No. 78 Furniture Row Racing Toyota.
Right behind him was Chase Elliott, who led Monster Energy Series practice earlier in the day, in the No. 24 Hendrick Motorsports Chevrolet at 188.574 mph.
Rounding out the top five were: Dale Earnhardt Jr. in the No. 88 Hendrick Motorsports Chevrolet at 188.436 mph, Matt Kenseth in the No. 20 Joe Gibbs Racing Toyota at 188.258 mph and pole winner Brad Keselowski in the No. 2 Team Penske Ford at 188.140 mph.
Late in the practice, Ricky Stenhouse Jr. scraped the right side of his No. 17 Roush Fenway Racing Ford against the outside wall. His car suffered significant damage, and he will use a backup car in Sunday’s Kobalt 400 (3:30 p.m. ET, FOX).
Earlier in the day, Elliott led Saturday’s first practice in the Monster Energy NASCAR Cup Series, wheeling his No. 24 Chevrolet around the 1.5-mile track at 191.510 mph.
Kyle Larson was second in the No. 42 Chip Ganassi Racing Chevrolet at 188.818 mph. A pair of Toyotas — Joe Gibbs Racing’s Kenseth and Kyle Busch — were third and fourth, respectively. Hendrick’s Kasey Kahne rounded out the top five in the No. 5 Chevrolet.
The top Ford team was Ryan Blaney in sixth place in the No. 21 for Wood Brothers Racing. Blaney qualified third for Sunday’s race with fellow Ford driver Brad Keselowski winning the Coors Light Pole Award.
NASCAR opened up the timing lines on pit road for practice, allowing teams to practice pit road speeds following the race in Atlanta when there were 13 penalties for speeding.
Meanwhile, three teams served practice penalties: Kahne’s No. 5 and Truex’s No. 78 failed templates twice in pre-qualifying inspection and lost 15 minutes of practice time. And Erik Jones’ No. 77 failed weights and measures three times and lost 15 minutes of practice time, along with pit selection.
