Stefanos Tsitsipas outlasts Taylor Fritz in five-set epic at Australian Open

Fourth seed Stefanos Tsitsipas survived a gruelling fourth-round battle with Taylor Fritz, twice coming from a set behind to win 4-6, 6-4, 4-6, 6-3, 6-4 and reach the Australian Open quarterfinals.

At just past midnight on Rod Laver Arena, the Greek ended 20th seed Fritz's resistance to set up a clash with Italian 11th seed Jannik Sinner.

He will be seeking to reach the semifinals at Melbourne Park for the third time in his career.

Tsitsipas looked out of sorts and edgy at times but his greater experience on the big stage eventually told as he got the decisive break in the ninth game of the fifth set before claiming victory.

Fritz converted only two of his 15 break points and will rue a missed opportunity to become the first American male to reach a quarterfinal at a major for two years.

«It was an epic match that's all I can say, I gave everything out there on the court today,» Tsitsipas said in his on-court interview.

«I'm proud of the way I fought.

»I'm overwhelmed. It's too good to be true. I knew it was going to be physical, and I knew I had to be patient and in the end it paid off."

Fritz used his destructive forehand to great effect throughout the contest and Tsitsipas looked under pressure in the first set, often struggling to beat the shot clock when serving.

The 24-year-old American broke serve at 3-3 in the opener with a clubbing forehand and calmly closed out the set.

Fritz did not even face a break point until 4-5 in the second set when he suddenly got tight and coughed up some errors.

Another forehand error allowed Tsitsipas to level the match although he initially seemed unaware the set was his.
