Daniil Medvedev v Dominic Thiem: US Open men’s semi-final – live!

First set: Medvedev 1-1 Thiem*

Medvedev cracks a 120mph ace out wide for 40-15, then follows with his first double fault of the evening and an unforced forehand error from the baseline to push it to deuce. But he holds comfortably from there, closing out the hold in his opening service game with a forehand volley winner at the net.

First set: *Medvedev 0-1 Thiem

Thiem holds in a cagey opening service game that included rallies of 13, 12, 13 and 17 strokes … and an uncharacteristic three unforced errors by Medvedev.

Daniil Medvedev can become the first player in the Open era (since 1969) to win the US Open men’s singles title without dropping a set. The 24-year-old Russian, who pushed Rafael Nadal to the limit over five sets in last year’s final, has swept 15 sets at this year’s tournament to reach this point.

Dominic Thiem, 27, has become the first Austrian semi-finalist in US Open history after a near miss in 2018, when he lost a fifth-set tiebreak to Nadal in the quarter-finals. The last player from Austria to knock on the door was the great Thomas Muster, who reached the US Open quarters in 1993, 1994 and 1996.

Bryan will be here shortly. In the meantime, today’s first semi-final between Pablo Carreño Busta and Alexander Zverev is into the fifth set and you can follow Tumaini Carayol’s minute-by-minute report here.
