There will be an American in the men’s final of the US Open for the first time since 2006 after Frances Tiafoe set up a blockbuster of a semi-final against Taylor Fritz.

Hours after Fritz disposed of fourth seed Alexander Zverev in the quarter-final, Tiafoe followed suit by beating an injured Grigor Dimitrov 6-3 6-7 (5) 6-3 4-1.
