Stefanos Tsitsipas was fortunate not to be kicked out of the Australian Open on Tuesday after almost hitting a ball kid in frustration.
Leading by two sets to love against unseeded Czech Jiri Lehecka, in the eighth game of the third set, Tsitsipas was beaten by a forehand winner down the line from his 21-year-old opponent.
As the ball bounced off the backboard, Tsitsipas angrily hit the ball against it with the ball kid just yards away and forced to hurriedly stop in their tracks.
On commentary for Australian broadcaster Channel Nine, former world No 1 and two-time grand slam winner Jim Courier said: "Tsitsipas just got really lucky. He swings in anger and nearly hits the ball kid. If it does, he is shaking hands as a loser in this match. You cannot do that, you have to be careful. That was dangerous.
"Linespeople are gone. [Novak] Djokovic got defaulted at the US Open a few years back for swatting the ball and it hit a linesperson. But there are still people on the court and if you hit them you are automatically disqualified."
Two games later, Tsitsipas moved through to the semi-finals, beating Lehecka 6-3, 7-6 (2), 6-4.
Lehecka had defeated Cameron Norrie and Felix Auger-Aliassime to make the last eight but was broken in his first service game and, although he put on a creditable display, it was not enough to take a set from Tsitsipas.
"I can say it was a fair dinkum type of performance," Tsitsipas said on court. "It felt different this time from the other time we played but I found a solution. I had to deal with groundstrokes that were coming at me heavy and deep. I put my heart out there."
Tsitsipas will now take on Karen Khachanov in the semi-finals on Friday.
Tsitsipas played a brilliant tiebreak in the second set. He showed his class. He was looking to dictate and be aggressive.
Tsitsipas's serving unbelievably well. It's become a huge weapon. He's figured out how to hit pretty precise. He's got the power.

Australia is such a great country. One of my favourite actresses comes from here - Margot Robbie! It would be nice to see her over there one day!
More Tsitsipas reaction
I like a lot of things in Australia, the people are very welcoming. I’ve said that so many times but I’ll keep saying it, because it’s very true. I grew up in a place that’s very similar in terms of conditions and lifestyle. I find myself feeling at home when I’m here.
It felt different this time from any other match, but the most important thing was that I found a solution.It was a very difficult three-setter, one of the most difficult ones that I’ve had so far in the competition. I think Jiri had a very good tournament. He’s someone who has started playing well recently and I wish him the very best for the future.

Aiming for the final four
Good morning and welcome to coverage of the second men's quarter-final of the Australian Open between Stefanos Tsitsipas and Jiri Lehecka.
Tsitsipas starts the match as favourite as he continues his bid to win the first grand slam of his career. The Greek star needed five sets to beat Italy's Jannik Sinner on Sunday and is now aiming to reach the last four in Melbourne for the fourth time.
Lehecka has enjoyed a tournament to remember, knocking out seeds Borna Coric, Cameron Norrie and Felix Auger-Aliassime to reach the quarter-finals of a major for the first time.
The two players have met just once before, in Rotterdam last year with Tsitsipas coming through in three sets.
And Lehecka says he is desperate to get one over the three seed.
"I will go for that revenge, for sure. I know that he will remember how we played last year in Rotterdam. One set I was the better player on the court," he said. "Then he overtook the match. But I think that he will remember, and he will know what my strengths are. He will feel that I can get him under the pressure. At the same time I know that he's a great player. I mean, he's No. 4 in the world. Anyway, I mean, if you are in top 10, then you must show some extraordinary tennis.
"I know how to play against him. Of course, the match last year from Rotterdam semifinal will help me a lot, how to imagine some things, how it went over there, how to prepare for this next matchup."
The winner of this match will play Karen Khachanov in the semi-finals later this week. The 26-year-old reached the last four when his opponent Sebastian Korda retired with a wrist injury while trailing 7-6(5) 6-3 3-0.
