Austin Dillon's No. 3 Chevrolet came to life late Saturday night, leading him to repeat as winner of the Cook Out 400 at Richmond Raceway and join the playoff field in the NASCAR Cup Series' penultimate regular-season race in Richmond, Va.

In successfully defending his title, Dillon became the race's first repeat victor since Denny Hamlin accomplished the feat in 2009 and 2010.

The Richard Childress Racing driver wrecked his way to victory last season through leader Joey Logano and Hamlin off the final turn.

But an aggressive pit stop -- coming in right after passing leader Ryan Blaney on Lap 340 -- allowed the 35-year-old from North Carolina to beat Alex Bowman's No. 48 Chevrolet by 2.471 seconds for his sixth career win and put him in the 16-car postseason.

Blaney finished third, followed by Logano, who started last for just the fourth time in his career. Austin Cindric was fifth.

A Chevrolet driver has now won three of the past five races at the -mile short track.

Polesitter Ryan Preece crept away from AJ Allmendinger and Tyler Reddick after earning his second career pole on Friday, while Hamlin slid up to third to start the season's fourth short-track race.

Despite most everyone taking tires at the midpoint as the rubber fell off, Preece stayed out and lost the lead to Reddick late. Bubba Wallace, Hamlin, Dillon and Cindric rounded out the top five in the 70-lap first stage.

Wallace's No. 23 led fellow Toyota driver Christopher Bell in the early portions of Stage 2, but after a full green-flag run in Stage 1, the second segment featured three cautions for incidents, including a 16-car pile that started with Chase Briscoe getting hit by Kyle Busch in Turn 3.

The melee included Hamlin, William Byron, Brad Keselowski and Reddick, who led 41 laps, among others. The No. 9 Hendrick Motorsports Chevrolet of Chase Elliott was retired from the event and finished last in 38th.

Wallace earned the top bonus points by clinching the segment. Daniel Suarez, Blaney, Dillon and Bowman were the next four finishers behind Wallace, who led a race-high 123 laps.

However, with Dillon pacing the field, Wallace's left-front tire came off as pit stops began near Lap 300, ending a strong run by the Brickyard 400 winner in Indianapolis last month.
