Frances Tiafoe is hoping to complete his “Cinderella story” by winning a first grand slam title at the US Open.

The 24-year-old became the first American man to reach the semi-finals of the singles at Flushing Meadows since Andy Roddick 16 years ago when he followed up his huge upset of Rafael Nadal by beating Andrey Rublev.
