Elliott Sadler missed the chance to clinch the regular-season Xfinity points title but maintained a sizable margin despite finishing 33rd in a late crash Saturday.
Sadler leads JR Motorsports teammate William Byron by 91 points in the standings with two races remaining in the regular season at Richmond International Raceway and Chicagoland Speedway.
The seven-race playoffs will begin with a 12-driver field in the Sept. 23 race at Kentucky Speedway. Sadler already had clinched a berth on points. William Byron, Justin Allgaier, Ryan Reed and Jeremy Clements have clinched playoffs spots with wins, leaving four berths open.
