Jon Rahm has world number one within reach after seizing pole position in Ohio

Memorial Golf

Jon Rahm will take a four-stroke lead into the final round of the Memorial Tournament as he bids to replace Rory McIlroy as world number one.

The Spaniard will top the Official World Golf Ranking for the first time if he wins and McIlroy, who finished the day 10 shots back in a share of 12th, finishes worse than a two-way tie for second.
