William Byron matched his win total from last season by finishing first in the United Rentals Work 500 at Phoenix Raceway on Sunday to mark his second straight win.

Byron needed overtime to capture his second NASCAR Cup Series win of the season. He got past Kyle Larson and held off a charging Ryan Blaney down the stretch to secure the win. Tyler Reddick would finish third with Larson in fourth and Kevin Harvick in fifth.

A late caution flag sent the race into overtime. On the restart, Byron sat on the outside of Larson and was propelled into first.

Byron credited his crew chief Rudy Fugle with sticking with two new tires at a strategic time to help him at least get into a position where he could catapult himself into first place. The strategy paid off when Byron drove the No. 24 car back to Winner’s Circle for the second time in a row.

The victory marks the sixth win of his career. He won last week in Las Vegas.

He also scored points with a win on Stage 1. Larson, who sat on pole during the race, finished first on Stage 2.

Byron is the first driver this season to have multiple wins. His wins give him a great shot at making the playoffs later this season. He started the race in third place. Christopher Bell, Chase Briscoe, Kyle Busch, Alex Bowman and Josh Berry rounded out the top 10.
