MEMPHIS, Tenn. – Jon Rahm is one of only two top-50 players missing from this week’s WGC-FedEx St. Jude Invitational, and that absence could jeopardize his No. 1 ranking.
Dustin Johnson and Collin Morikawa each have an opportunity to move to world No. 1 based on their play this week at TPC Southwind.
Johnson could leapfrog Rahm and return to the top spot with no worse than a two-way tie for second, assuming Morikawa doesn’t win. Johnson shot 1-under 69 in the opening round and was tied for 36th.
Morikawa would ascend to No.
