Spain’s Jon Rahm will take over as world number one if he can convert his four-shot lead into victory in Sunday’s final round at the Memorial Tournament.
Rahm holed four birdies in succession from the 13th as he hit a four-under 68 to lead on 12 under from Americans Ryan Palmer and Tony Finau, who had 73s.
England’s Danny Willett is fourth on six under after a 70 in Ohio.
World number one Rory McIlroy stayed at two-under after a 72, while Tiger Woods had a 71 to improve to two over par. (BBC)
