The Power 18 golf rankings: Scottie Scheffler extends gap over peers as Jon Rahm rises with U.S. Open ahead

With three wins in our starts, Scheffler is back to being seemingly unstoppable on the PGA Tour

There was a point this season -- not too long ago, in fact -- where many believed Rory McIlroy had usurped Scottie Scheffler as the game's best despite what the Official World Golf Rankings and many metrics may have stated. That point is now in the distant past as Scheffler's surge across the month of May zoomed him well past any contemporaries as the long summer of professional golf begins.

The 16-time PGA Tour winner has added three more trophies to his mantle -- all in the last four weeks since we last took stock of The Power 18, ranking the best-performing players in golf. Scheffler stood at No. 1 then, and he stands at No. 1 now because, well, there is nowhere higher to put him.

Scheffler tied the PGA Tour scoring record at the CJ Cup Byron Nelson, won by five strokes at the PGA Championship (for his third major championship) and clipped the field by four at Jack's Place for his second straight Memorial title, making him only the second successful tournament defender at Muirfield Village in history (Tiger Woods, 1999-2001).
