NASCAR CUP SERIES
Denny Hamlin
Age: 44
Hometown: Chesterfield, Virginia
Cup championships: 0
Best points finish: 2nd (2010)
Crew chief: Chris Gayle
Team: Joe Gibbs Racing
2025 wins: 6 (Martinsville I, Darlington I, Michigan, Dover, Gateway, Las Vegas II)
2025 top-five finishes: 14
2025 top-10 finishes: 17
Championship 4 appearances: Fifth (2014, ’19, ’20, ’21, 25)
Outlook: Is this the year Denny Hamlin, who will turn 45 shortly after the season, claims his first Cup championship? Could it come in a year when 23XI Racing, a team co-owned by Hamlin and Michael Jordan is in a lawsuit against NASCAR that is headed for trial Dec. 1? Hamlin’s runner-up finish at Phoenix in the spring was the best result among the four championship contenders. He and his team have had two extra weeks to prepare for this race after winning the Round of 8 opener at Las Vegas. Three times in the last four years the winner of the Round of 8 opener has taken advantage of that extra time to win the Cup championship.
Chase Briscoe
Age: 30
Hometown: Mitchell, IN
Cup championships: 0
Best points finish: 9th (2022)
Crew chief: James Small
Team: Joe Gibbs Racing

2025 top-five finishes: 15
2025 top-10 finishes: 19
Championship 4 appearances: First
Outlook: Makes title race in his first season with Joe Gibbs Racing, taking over the No. 19 ride from Martin Truex Jr., who retired from full-time racing after last season. Briscoe has been fast all season, scoring a seres-high seven poles. He scored two wins, five top-five finishes and seven top-10 results in the playoffs.
William Byron

Hometown: Charlotte, North Carolina
Cup championships: 0
Best points finish: 3rd (2023, ‘24)

2025 top-five finishes: 11
2025 top-10 finishes: 16
Championship 4 appearances: 3rd (2023, ’24, ’25)
Outlook: Byron won the regular season and makes his third consecutive Championship 4 appearance after his dominating Martinsville victory last weekend. Byron has won the past two Daytona 500s. He has led a series-high 1,278 laps this season. He finished sixth at Phoenix in the spring, leading 83 laps. He looks to give the No. 24 car at Hendrick Motorsports its first Cup title since Jeff Gordon won his fourth and final crown in 2001.
