Rafael Nadal continued his relentless march towards an 18th major title on Tuesday . Second seed Nadal inched closer to winning an event he has only claimed once before when he trounced unseeded American Frances Tiafoe 6-3, 6-4, 6-2 in another ruthless display from a man who has not dropped a set so far.

Tiafoe had announced himself by beating fifth seed Kevin Anderson but was no match for a player at the peak of his powers as he attempts to become only the third man to win all four Slams twice and the first to do so in the Open era. 

"I had some trouble at this event all my career, so I'm very happy with the way I played tonight," said the Spaniard, who faces another young gun Tsitsipas in the semi-finals. 

"I feel lucky to be where I am."
