JR Motorsports teammates Connor Zilisch, Ross Chastain, and Justin Allgaier were involved in a crash during Saturday’s Xfinity Series race at Iowa Speedway. Following a restart on Lap 213, Zilisch, who was chasing his fourth win in a row, made a mistake that sent Chastain into Allgaier’s No. 7 Chevy.Zilisch was underneath Chastain’s No. 9 at the time, with Allgaier running three-wide. The JR Motorsports newcomer got loose in Turn 1, and that’s when things got out of hand. He did address the issue with Chastain after the race, with the latter saying that he could have probably done things differently. Zilisch, on his part, felt like he could have gone into the corner while maintaining a distance.During a post-race interview with Bob Pockrass of FOX, Zilisch apologized to Allgaier, the reigning series champion.“I feel really bad for the #7 and Justin,” Connor Zilisch told Pockrass. “ I hate that I did that to them. I was pretty upset at myself about that one. Whether it was completely my fault or not, I take responsibility, and I apologize to the #7.”Sam Mayer, driver of the No. 41 Mustang for Haas Factory Team, won the 250-lap event, marking his maiden win of the season and bagging a spot in the 2025 playoffs at the same time. Rounding off the top five were Jesse Love, Chastain, Zilisch, and former Cup driver Harrison Burton. Allgaier finished 16th, picking up a total of 22 points on the way.Next up for the drivers is the Mission 200 race at Watkins Glen International. Scheduled for next Saturday, August 9, the 82-lap event will be televised on CW, with live radio updates on MRN and SiriusXM NASCAR Radio starting at 3 pm ET.Connor Zilisch loses his cool on the radio during Saturday’s HyVee Perks 250Connor Zilisch dropped to the back of the field, having to pit twice (due to a loose wheel) after Stage 1.
