Truex went out early in the final round of Saturday’s qualifying session and held to win the pole for Sunday’s race at Homestead-Miami Speedway.
Although he won the regular season title, Truex has struggled in the playoffs with no finish better than ninth.
His average lap speed on of 167.411 mph edged fellow Toyota driver Bubba Wallace (167.115 mph) to claim his second pole of the season and 22nd of his career. It’s also the 500th pole by a Toyota driver in NASCAR’s three national series – Cup, Xfinity and Trucks.
“I actually thought we could have been a little bit better there,” Truex said. “You never know here. Scuff tires are always a challenge. Pretty good to get that pole for Toyota and a great start for us as well.
“Based on my past experience here I think we are close enough to be good later in the day (in the race) when the track gets slick. With these cars, you just never know what direction it could go. I can be a complete curveball.
“We just need to make smart adjustments tonight and figure out what the pace is going to be and where I want to run and go from there.”
Toyota completed a sweep of the top three positions with Tyler Reddick in third, Brad Keselowski was fourth and last week’s race winner, Kyle Larson, rounded out the top five.
Completing the top-10 starting lineup are Austin Dillon, William Byron, Ross Chastain, Ty Gibbs and Ryan Blaney.
