World No 2 Daniil Medvedev broke down in a furious tirade aimed at the umpire during the second set of his semi-final against Stefanos Tsitsipas at the Australian Open.
Medvedev - no stranger to controversy Down Under - took the first set 7-6 (7-5) before the second was tied at 4-4 with the 25-year-old on serve. He double-faulted either side of a horrible forehand to gift Tsitsipas a crucial break, before Medvedev himself appeared to reach breaking point.
He aimed his fury at umpire Jaume Campistol on the changeover, and had another go at the official, like Nick Kyrgios did earlier this tournament, once he lost the set as Tsitsipas hyped the crowd up against his opponent.
