Heavyweight battles dominate quarterfinals of NASCAR's In-Season Challenge

Following Chase Briscoe's first win of the season and a Joe Gibbs Racing 1-2-3 finish in NASCAR's return to Chicagoland Speedway, the Cup Series sets its sights on Atlanta's EchoPark Speedway for a Sunday night affair (7 p.m. ET, TNT, truTV, HBO Max, PRN Radio, SiriusXM NASCAR Radio).

That also means that the second edition of the In-Season Challenge is now down to its final eight drivers as the head-to-head, bracket-style competition for the $1M prize heats up.

While No. 32 seed Alex Bowman outlasted No. 16 seed Austin Cindric and No. 25 Todd Gilliland continued his surprising run by eliminating No. 9 Carson Hocevar, the rest of the bracket has been a lot more straightforward.

Intriguing matchups on tap at EchoPark Speedway

Aside from the head-to-head between Bowman and Gilliland, the remaining three matchups each feature drivers in the top 12 of the standings.

Fresh off his Chicagoland win, the No. 12 seed Briscoe is set to square off against No. 4 Chase Elliott. With six top-fives in the last 12 races, Briscoe continues to bring his best to JGR following a slow start to the season marred by missed opportunities and unfortunate circumstances on the track.

Elliott, meanwhile, is still searching for his first top 10 since Nashville on May 31. Still, he has a pair of wins this season and is the defending winner of the EchoPark Speedway summer race, making this a must-see battle. 

The matchups are arguably even more enticing on the other side of the bracket as points leader and No. 2 seed Denny Hamlin faces No. 10 Christopher Bell in a JGR tilt and No. 11 William Byron clashes with No. 3 Ryan Blaney.

Hamlin may have the advantage in the wins department (four to Bell's zero), but Sunday's runner-up at Chicagoland was Bell's fourth second-place finish in a season of near-misses.

Bell also has the upper hand with one win on the current configuration at EchoPark Speedway (2025 spring race), while Hamlin has just two top-10s in those nine races. With that said, Hamlin typically excels at drafting-style racing and it would not be a surprise whatsoever if these two are battling near the front on Sunday.

Finally, Byron and Blaney face one another after coming away with top-10s at Chicagoland. While Byron has had an uncharacteristic season and currently sits 12th in points, he led a race-high 94 laps before settling for fourth just outside the "Windy City."

Blaney, on the other hand, continued to be the torchbearer for Ford in seventh, good for his series-leading 14th top 10 of the season. Both drivers are also previous winners at EchoPark Speedway, though Blaney's victory in 2021 came before the current configuration.

Now, the racing at EchoPark Speedway is unlike anything the series experiences anywhere else as handling typically plays a role and creates more opportunities for drivers to make moves.

As last season proved when the In-Season Challenge kicked off at EchoPark Speedway, this type of racing could prevent these intriguing matchups on paper from living up to their potential due to the threat of the "Big One" that can strike when the field is packed up.

However, that does not take away from the competitive nature of these head-to-head battles and why these three, specifically, can go down to the wire if each driver can avoid trouble.
