Stefanos Tsitsipas followed up his landmark victory over Roger Federer by beating Roberto Bautista Agut to reach his first grand slam semi-final at the Australian Open.
Backing up breakthrough moments is notoriously difficult but Tsitsipas bucked the trend by battling to a 7-5, 4-6, 6-4, 7-6 (2) win in three hours and 15 minutes.
The 20-year-old Greek had to dig deep on Rod Laver Arena, coming from a break down in the first and third sets before proving stronger in the fourth.
He fell to the court when Bautista Agut’s final return hit the net and can look forward to a clash against either Rafael Nadal or Frances Tiafoe on Thursday.
Tsitsipas’ achievement makes him the youngest man to reach the last four at Melbourne Park since Andy Roddick in 2003 and the youngest at any slam since Novak Djokovic at the US Open in 2007.
He said: “It all feels like a fairytale almost. I’m just living the dream, living what I’ve been working for. I feel a bit emotional but not too much because I know I really worked hard to get here.”
