Paul Casey believes Dustin Johnson can dominate the game if he manages to maintain his current high standards.
Johnson was, for many years, the nearly man after several near-misses in the four major tournaments and there was a huge question mark over his mental strength.
However, the American big-hitter managed to break his duck at the 2016 US Open and he has gone from strength-to-strength ever since that victory at Oakmont Country Club.
The 32-year-old won two more PGA Tour titles last year and the momentum has been taken into 2017 with victories in the Genesis Open and WGC-Mexico Championship.
Johnson recently became the world number one and is currently one of the most feared players in golf after managing to finally conquer the mental demons that had hampered his progress.
Casey, who is currently 15th in the world rankings, has praised the latest performances of the US Open champion and the Englishman expects him to enjoy more success this year.
Casey told stuff.co.nz: “He has the potential to crack on for the next few years or a decade and be the dominant player, if he plays the golf we’ve seen him play.”
Johnson will have two weeks at home before embarking on the road to Augusta National for the Masters, where he will play the Dell Match Play and the Shell Houston Open before the first major of the season.
