All four players in the US Open men’s semi-final are gunning for a maiden Grand Slam crown while two of the four are also bidding to become world No 1.

Casper Ruud and Karen Khachanov will be going head-to-head in the first match on Arthur Ashe Stadium on Friday while Carlos Alcaraz and Frances Tiafoe will play in the late match on the showpiece court.

Of the four, Ruud is the only one to have played in a major final with the Norwegian finishing runner-up to Rafael Nadal at Roland Garros earlier this year.

“It’s like one more step forward,” Khachanov said after beating Nick Kyrgios in the quarter-final. “I’m really, really happy I could do it.”
