Chase Briscoe has a series-leading six pole positions in 2025, but the Joe Gibbs Racing driver has yet to convert any of those poles into a race win. At Iowa Speedway, he came fairly close, finishing second to William Byron and Hendrick Motorsports.

It’s the second consecutive pole position for Briscoe, after a special hometown pole last weekend at Indianapolis Motor Speedway, and a series-leading sixth of the 2025 NASCAR Cup Series campaign. Before joining JGR this season, the 30-year-old driver had only recorded two poles.

One week after claiming the pole for the Brickyard 400, Briscoe laid down a quick lap of 136.933mph (23.093s) to take the top spot again for the Iowa Corn 350 at Iowa Speedway.
