Keep up with this weekend's action from Las Vegas Motor Speedway in our exclusive event notebook. 

Kevin Harvick scored his sixth consecutive first/second place finish as he captured the win in the Kobalt 400 at Las Vegas Motor Speedway. He also shredded his right year tire as he celbrated his first win of 2015 in the third race of the season.

“It’s so cool to win here in Las Vegas and start this West Coast swing off this way is pretty awesome,” exclaimed Harvick from Victory Lane. “Just to be in front of all these fans I’ve raced in front of since about the mid-‘90’s. It’s pretty special to win here. I’ve got to thank Jimmy John’s, Budweiser, Chevrolet, and everybody on this car that makes it go around; and all these guys and everyone at Stewart-Haas for what they do.”

Former xfinity series champion Austin Dillon capped off a perfect Las Vegas xfinity weekend with his win in Saturday's Boyd Gaming 300. Dillon, driver of the #33 Rheem Chevrolet, led 183 of 200 laps en route to his third career xfinity series victory.

In addition to winning Saturday's race, Dillon also qualified on the pole for the event and was the fastest competitor in Friday's xfinity practice session.

Even though Dillon did lead a vast majority of the laps, he did not cruise to an easy victory. A hard charging Ryan Blaney forced Dillon to block almost every lane on the mile and a half racetrack over the final three laps.
