Justin Thomas, Ricky Fowler and Harold Varner III shot opening-round, 7-under-par 64s to share the top spot in the Waste Management Phoenix Open on Thursday in Scottsdale, Ariz.

Thomas, who began on the back nine, notched a 5-under mark on the front side of TPC Scottsdale.

Fowler was buoyed by an eagle on the par-5 13th as part of a 4-under score for his first eight holes.

Thomas and Fowler are connected in more ways than on the leaderboard this week. They are sharing a house during the tournament.

“It was very, very hard to get the balls close to the pin early in the round,” Thomas said. “But just continued to try to stay patient and was driving it well to where I had wedges and I made some very low-stress birdies.”

Varner, who played in the afternoon, caught up with the early leaders with birdies on three of his final six holes.

J.T. Poston and Scotland’s Martin Laird are both one shot back after 65s.
