Daniil Medvedev, Stefanos Tsitsipas fined after controversial Australian Open semifinal

Daniil Medvedev has been fined just over $17,000 following his extraordinary outburst at the chair umpire in his fiery Australian Open semifinal win over Stefanos Tsitsipas on Friday night.

Medvedev took aim at chair umpire Jaume Campistol when he accused Tsitsipas of receiving illegal coaching from his father in the stands.

»I asked him [Campistol] if he [Tsitsipas's father] can talk. He said he can talk but he can't coach.

«Then I said, 'Do you speak Greek? If not, the guy is talking, talking, talking'. I don't know what he says.

»I don't consider coaching as cheating but it should be a code violation."

Medvedev — who shares a heated rivalry with Tsitsipas — said he should not have spoken to Campistol in the manner in which
