Tyler Reddick paced the NASCAR Cup Series field in Friday's practice session from Nashville Superspeedway, putting his No. 45 The Big 615/MoneyLion Toyota Camry TRD atop the list of favorites for Sunday's Ally 400.
Reddick, searching for his second victory of the year with 23XI Racing, posted a time of 29.510 seconds (162.250mph) to lead the 50-minute practice session.
Alongside his well-documented single-lap pace, the Corning, California native was the quickest driver in 10-lap averages during the session.
Martin Truex, Jr. laid down the second-fastest overall time in Friday's practice, more than a tenth of a second behind his fellow Toyota teammate, Reddick.
The Joe Gibbs Racing driver, who is in search of his third victory of the season, led the 36-car field in five-lap averages over Reddick, Chastain, Wallace, and Byron.
Ross Chastain was third-place in Friday's practice, while Erik Jones and William Byron recorded laps inside the top five on the overall speed charters.
Bubba Wallace, Denny Hamlin, Chase Elliott, Chris Buescher, and AJ Allmendinger rounded out the top-10 in the practice session.
Chastain, third-quickest overall, would lead the field in both 15 and 20-lap averages over the course of the session, while Kyle Larson led the field in 25-lap averages.
Kyle Busch, who ended up 21st in the session, had the only on-track incident, when his No. 8 Chevrolet Camaro spun at the exit of turn four, as a result of snapping loose.
The NASCAR Cup Series will regroup for qualifying on Saturday, as the drivers earn their starting position for Sunday's Ally 400 at Nashville Superspeedway. Qualifying will begin at 1:00 PM ET.
