FORT WORTH, Texas (AP) — Brad Keselowski won the NASCAR Xfinity race at Texas, leading a race-high 62 of 200 laps and wrapping up a third consecutive owners' championship for Roger Penske.
While Penske got a title Saturday, the Xfinity drivers' championship is still undecided with two races left.
Points leader Chris Buescher finished 11th and has a 24-lead over defending champion Chase Elliott, who finished eighth. Regan Smith was 31 points behind after finishing ninth.
Keselowski has two series victories this year and 34 overall. He had an average speed of 139.607 mph in the No. 22 Ford to finish ahead of Kevin Harvick, Austin Dillon and Erik Jones.
Jones won the Camping World Truck race Friday night and is driving in place of suspended Matt Kenseth on Sunday in the Sprint Cup race at the high-banked, 1 1/2-mile track.
There were 17 lead changes among seven drivers, none of them being the top three championship contenders.
Kyle Larson led 50 laps, and was in leading on the 175th lap when a rubbing left tire finally went down coming out of the fourth turn and he was passed by Harvick.
Keselowski led six times, taking the lead for the last time with 11 laps remaining.
Busch, who has won three truck races at Texas, finished 14th after being unable to get his car out of fourth gear because of a shifting problem most of the second half of the race.
The Xfinity race was run after two scheduled Cup practices earlier in the day were canceled because of a wet track after several hours of drying the track. There were no apparent problems for Xfinity drivers.
Workers drilled holes in some areas of the 1 1/2-mile, high-banked track in an effort to help drain water from underneath the asphalt. North Texas has been saturated by rain in the last couple of weeks.
Keselowski, one of the eight remaining contenders for the Chase championship, is the polesitter Sunday.
