tiebreaker to win as he struck an overhead winner while Murray netted a down the line backhand return before double faulting to end the set.

Murray took set three 6-3 before falling behind 0-5 in set four.

Tsitsipas took set four then left the court for a controversial bathroom break which lasted eight minutes.

Upon Tsitsipas' return to the court, Murray appeared bothered and annoyed by what he perceived as a stall tactic from his opponent.

"It's just disappointing because I feel it influenced the outcome of the match," Murray said of Tsitsipas' bathroom break.

"I'm not saying I necessarily win that match, for sure, but it had influence on what was happening after those breaks. I rate him a lot. I think he's a brilliant player. I think he's great for the game. But I have zero time for that stuff at all, and I lost respect for him."

In the final set, the Greek broke Murray's opening service game before taking leads of 4-2 and 5-3.

Murray held serve to reach 5-4.

Serving for the match, Tsitsipas struck an inside out down the line forehand winner to lead 15-0.

Murray netted two down the line backhands to end the match.

Afterwards the two players engaged in an icy handshake at the net.
