Five storylines for the WM Phoenix Open: Can anyone stop Scottie Scheffler?

In five career starts at the WM Phoenix Open, Koepka has two wins, a T3 finish and gained strokes from putting in all five. Don't be surprised if he contends for a win this week. 

Jordan Spieth back in his happy place

Spieth has fallen out of the limelight recently due to injuries and poor play, but maybe a return to TPC Scottsdale is exactly what he needs to get back in contention. In his last five starts at the WM Phoenix Open, the American has four top-six finishes. His T4 last year was tied for his best finish of the season. 

Spieth is dying to get back in the mix on Tour, and this is where he can do just that. 

Collin Morikawa searching for form

Morikawa has only played the WM Phoenix Open twice (cut, T25), but he's in the field this year and hoping to build some momentum. The 28-year-old has just one top-10 finish since the Players Championship last March, and he missed the cut in his season debut at the Sony Open.

Morikawa has lost strokes from putting in nine of his last 10 recorded starts. Can he figure out the flat stick and make some noise this week?

Will the Phoenix faithful behave?

This one's a bit more complicated. The WM Phoenix Open is a party in the desert disguised as a golf tournament, so fans have gotten carried away over the years. We've seen inebriated fans run on the course, make snow angels in bunkers and even shower the 16th green with beverages after a hole-in-one. 

Security has cracked down on rowdy fans recently, so we'll see if the tournament can keep fans in check this year.
