PGA Tour: Ryo Hisatsune surges into the lead after second round at Phoenix Open

Fellow Japanese Hideki Matsuyama, a two-time Phoenix Open winner, had a run of six straight birdies to shoot 64 in the morning wave to take the clubhouse lead at 10 under.

Top-ranked Scottie Scheffler closed out for a 65 to be seven shots back at 4-under but Brooks Koepka had a much tougher go of it, finishing at 2-over to miss the cut.

First-round leader Chris Gotterup shot 71 to join Pierceson Coody (68) at 8 under.

Scheffler said after his round: "I've always been a proponent of saying you can't really find it during the tournament week, but I found a little something in my grip yesterday that seemed to really help me get my hands more securely on the club.

"Struck it much better today. Felt a bit lost out there at times yesterday, so today felt a lot better. Felt more in control of my game.

"You can obviously see that through the cleaner card today."
