Fowler went out early on Friday and shot an 8-under 64 on the Nicklaus Tournament Course at PGA West. He's made only one bogey through two rounds to sit at 15-under par.
Scheffler posted a 64 too, though his scorecard shows a double-bogey. It's the third time during the 2019-20 season the 23-year-old has held a piece of a 36-hole lead.
Here's how the top of the leaderboard stands after Round 2:
|Place||Player||To Par||R2 Score|
