Rahm finished tied for third Sunday at The Open Championship, making him the only golfer to finish in the top 10 at each of the season's four majors.

With Rahm's withdrawal, Dustin Johnson (No. 2) and Brooks Koepka (No. 7) are the only current top-10 golfers who are committed to the WGC event in Memphis.
