FORT WORTH, Texas (AP) - Kyle Busch keeps extending streaks at Texas in search of a NASCAR first.

Busch won his fourth consecutive Nationwide Series race at the 1 1/2-mile, high-banked track Saturday, a dominating victory a day after winning his fifth truck race in a row this season.

He will try to complete an unprecedented trifecta Sunday and become the first driver ever to win all three of NASCAR's national series on the same weekend.

After taking the lead on the 11th of 200 laps, when he swung around polesitter Matt Kenseth in the first turn, Busch went on to win by 3.154 seconds over Casey Mears.

Busch is 0-for-9 in Sprint Cup races at Texas, where finished 18th in April.
