SPARTA, Ky. — Brad Keselowski took his final lead on the 156th lap and went on to a rain-shortened victory Friday night in the NASCAR Nationwide Series race at Kentucky Speedway.

Showers halted the race at lap 170 in the scheduled 200-lap event, but drivers were expecting it to resume before another pocket of rain forced officials to call it off. Keselowski settled for doing victory spinouts, being careful to avoid sliding into the wall on a night mostly spent on firm footing.

A night after finishing second in the Truck Series race, the Sprint Cup champion led four times for 59 laps en route to his second series victory here in three years. Elliott Sadler was second, followed by Truck Series points leader Matt Crafton, Brian Vickers and Kyle Busch.

Series points leader Regan Smith saw his 28-point advantage over Justin Allgaier coming in whacked to an eight-point edge over Sam Hornish Jr. after an engine problem that forced him behind the wall and left him 30th, 17 laps down.
