Justin Thomas, Rickie Fowler, and Harold Varner III all shot 7-under 64 over the first 18 holes of what's sure to be a neck-and-neck race no matter who ends up the champ at the end as TPC Scottsdale this course has produced three straight playoffs. 

The trio combined for 21 birdies and an eagle, and Thomas made six 3s on the front nine of the course, his back nine. Fowler has a pretty good history at this tournament, he lost to Hideki Matsuyama in a 2016 playoff, and Thomas is coming in off back to back top 20s in the Hawaii swing.

Fowler led the PGA Tour in Round 1 scoring last season but his average faded as the week wore on.
