William Byron earns Pocono pole over Kyle Busch

Byron is now equal with Kevin Harvick with a season-leading three poles each. The 21-year-old also won pole position for this year's Daytona 500 and Coca-Cola 600.

Byron's lap of 173.494mph was 0.260 seconds clear of his closest competitor, Kyle Busch. For Busch, this outside pole is his best qualifying effort so far this season.

Clint Bowyer, Erik Jones, Brad Keselowski, Denny Hamlin, Kyle Larson, Jimmie Johnson, Daniel Suarez and Austin Dillon will round out the top-ten.

During the session, there was just one incident caused by J.J. Yeley when he spun off of Turn 2, narrowly keeping it out of the inside wall.
