SPARTA, Ky. -  Kentucky Speedway's ARCA Racing Series (ARS) Crosley Brands 150 has been postponed to Saturday, Sept. 26, at 1 p.m., due to rain.

Speedway gates will open at 11 a.m., and Crosley 150 tickets also will be honored for admission to the NASCAR XFINITY Series VisitMyrtleBeach.com 300 slated for an 8 p.m., green flag.

The Crosley 150 will air live on FOX Sports 2.

William Byron led a Venturini Motorsports front-row sweep in Crosley Brands 150 qualifying.

The 17-year-old, making his ARS superspeedway debut in the No. 55, took the top spot with a lap of 177.427 mph.  

"I learned a lot today," Byron said. "I got a little overaggressive in practice and spun. But I learned from it and came back strong in qualifying. Just really proud of this Venturini Motorsports team. They brought a fast Toyota for me. I'm looking forward to the race."

Teammate Daniel Suarez, one of three drivers entered in the Crosley Brands 150 and VisitMyrtleBeach.com 300, qualified second for the Crosley 150 with a 175.610 mph lap. He led 39 VisitMyrtleBeach.com 300 laps last September and finished fifth.

Travis Braden is set to start the race third and was followed by Austin Cindric, Will Kimmel and Ross Kenseth. Series championship leader Grant Enfinger, who has won six times this season, will start 12th in the No. 23.

Byron leads Scott Heckert in the NASCAR K&N Pro Series East championship standings with one race remaining on that series' schedule. Heckert will start the Crosley 150 35th.

"Going this fast is something new to me," Byron said. "I'm still getting used to that part but I really enjoy every lap. It's so fast, so fun, and I've got a fast car.
