'One player is going to die' - Medvedev wins in heat
Medvedev called for two separate medical timeouts as he appeared to struggle with his breathing
Daniil Medvedev reached the US Open semi-finals after beating Andrey Rublev in hot and humid conditions that he said would cause a player to "die".
The third seed appeared to struggle with his breathing but won 6-4 6-3 6-4 against his fellow Russian.
"One player is going to die and you are going to see," he said into a camera during the match in New York.
Medvedev won his only Grand Slam at the US Open in 2021 after beating Novak Djokovic in the final.
Rublev has now failed to make the semi-final of a major in nine attempts.
Playing under a partially closed roof because of the heat, Rublev got off to a great start in his bid to get over the Grand Slam quarter-final hurdle as he raced to a 3-0 lead, but it did not take long for Medvedev to find his form and get things back on serve.
