A top-tier PGA Tour field descends on TPC Scottsdale this week for the 2022 WM Phoenix Open, which tees off Thursday with six of the world's top 10 players in action. There are numerous former champions in the field, including two-time winners Hideki Matsuyama and Brooks Koepka, who won last year at 19 under.

World No. 1 Jon Rahm is the 15-2 favorite in the latest 2022 WM Phoenix Open odds from Caesars Sportsbook. Justin Thomas is at 12-1, followed by Viktor Hovland and Patrick Cantlay at 16-1. Matsuyama is the 18-1 fifth choice, while Koepka is listed at 30-1. Before you lock in any of your Fantasy golf rankings or bet the 2022 WM Phoenix Open, you HAVE TO see what fantasy expert Riley Gates has to say.

Gates is a writer for 247Sports and has covered a range of sports for nearly five years. He has followed golf closely for much longer and has a profound knowledge of the sport. He also knows what it takes to win, on the course and in fantasy sports.  

In last week's picks for the AT&T Pebble Beach Pro-Am, eight of Gates' selections finished in the top 16, with his top three all posting top-10 finishes. That included Jordan Spieth, who rallied from 11 strokes down after 36 holes and fell just short of the victory,

The expert has been on a roll all season. At The American Express, four of his top five selections finished in the top 15, and he NAILED his picks at the Sentry Tournament of Champions, with four of his top seven picks posting top-five finishes. 

At the Hero World Challenge, again four of his top seven finished in the top five. Anyone who has followed Gates is WAY UP! 

Now, the expert has ranked his top 20 golfers for the 2022 WM Phoenix Open, and you'll really want to see who he is backing. 

We can tell you he is firmly behind Matsuyama, who has won twice on this course and has been playing as well as anyone this year. The Japanese star has won two of his past four tour events, and he is accurate off the tee and hits his greens. Both skills are critical at Scottsdale, where Matsuyama won back-to-back tournaments in 2016 and '17. Gates expects him to keep rolling and highly recommends him for your Fantasy golf picks.    

On the other hand, the expert is slightly fading Viktor Hovland, who is one of the favorites but has been spending most of his time in Europe recently. The world's third-ranked player won in Dubai two weeks ago and tied for fourth the previous week in Abu Dhabi. But he could need time to adjust, and while he won at Mayakoba, he has been outside the top 15 in his other three PGA Tour events this season. Hovland doesn't crack Gates' top five options for your Fantasy golf picks for this week!

Instead, the fantasy expert is backing a HUGE long-shot who is listed at around 40-1! This veteran has shot in the 60's in 12 of his last 15 rounds and has the results to prove it. He has been hitting a lot of greens and putting well, which is always a recipe for success. Gates sees him as a must-play for your Fantasy golf picks for the WM Phoenix Open at TPC Scottsdale! You ABSOLUTELY need to see who it is and check out Gates' top picks before you bet the 2022 WM Phoenix Open or enter any Fantasy golf picks.
