LONG POND, Pa. -- Denny Hamlin earned the top seed in the inaugural version of NASCAR's In-season Challenge, a five-race, bracket-style tournament set to kick off next week in Atlanta.

The tournament, which comes with a $1 million prize to the winner, is part of a new media rights deal that includes TNT.

The final 32-driver field was set by results of the races at Michigan, Mexico City and Pocono. Chase Briscoe won the Cup race Sunday at Pocono Raceway to finalize the field.

The drivers will be paired in head-to-head matchups based on seeding, with the winners advancing to the next round in a bracket format that mirrors the NCAA basketball tournaments.

Hamlin goes head-to-head next week against the 32nd seed, Ty Dillon. Briscoe earned the second seed, Chris Buescher is third, Christopher Bell fourth and Chase Elliott fifth.

The format is single elimination with the field cut to 16 at Chicago, eight at Sonoma, four at Dover and the final two at Indianapolis Motor Speedway.

The tournament is patterned after in-season tournaments that are staged by soccer leagues around the world and even brought to the NBA.
