Busch won the Cup Series race Sunday and the X-finity Series race Saturday. Martin Truex, Jr. was the runner-up, followed by Ryan Blaney.
Rowdy will now head to Auto Club Speedway, where he will aim to set history as he races in another double headed weekend.
Chase Elliott rallied to ninth by the end of the stage after getting slapped with a pass-through penalty by edging Blaney at the start-finish line at the beginning of the race.
"Not for me to worry about", he said. "But for myself and the view I've had, I've been fortunate to be around a lot of great people and a lot of great sponsors".

The race was also Busch's first driving the red Skittles paint scheme this season.

Seven-time series champion Jimmie Johnson is among those starting midway through the field, while Daniel Suarez and Michael McDowell are near the back after their qualifying fight Friday.

Nine-time Phoenix victor Kevin Harvick finished ninth.
In the final segment, Elliott reported a vibration before spinning on the next lap, bringing out a caution. "I tried to jam on the brakes as hard as I could".
Busch made his move following a restart on Lap 239 of the 312-lap race.
To get the victory, Busch had to track down Blaney of Team Penske - who led 95 laps - over the final 50 laps.
