Stefanos Tsitsipas could barely get words out of his mouth minutes after knocking out a legend in the Australian Open. So dazed was he that when he was being interviewed on court by another tennis legend, he apologetically asked John McEnroe to repeat a question. It took time for him to register that he had actually eliminated tournament favourite Roger Federer 6-7 (11-13), 7-6 (7-3), 7-5, 7-6 (7-5) in the fourth round, at the same time achieving the distinction of being the first player from Greece to reach the quarterfinals of a Grand Slam.
The 14th seeded Tsitsipas (ATP world rank 15th in Men's Singles) stretched Federer in the first set, conceding it in the tie-breaker but fought back in the next two sets. The fourth set was just as tightly contested as the others, with the 37 year old Federer not letting up, but the Greek created an upset by taking the match with the first available match point.
On Tuesday, he defeated Roberto Bautista Agut 7-5 4-6 6-4 7-6(2) to enter the semi-final.
Born in Athens, Greece, Tsitsipas hails from a tennis family. His parents worked as tennis instructors at a resort and his father is currently his coach.
The highlight of his junior career was when he claimed the Boys Doubles title at Wimbledon in 2016, becoming the first male Greek player to claim a junior Grand Slam title in the Open era.
He played his first ATP main draw at Rotterdam in 2017. The same year, he made his Grand Slam debut, at the French Open. He didn't go past the first round both at Paris and at Wimbledon.
He made rapid strides in 2018, getting to the fourth round at Wimbledon before losing to John Isner. He reached the final at the ATP Barcelona Open, but couldn't match Rafael Nadal.
At the Canadian Open in Toronto, he outclassed big names including Dominic Thiem, Novak Djokovic, Alexander Zverev and Kevin Anderson to set up another final with Nadal. He lost again but made up for it by winning the Stockholm Open, defeating Ernests Gulbis. On a roll, he then claimed the ATP Next Gen title in Milan, defeating Alex de Minaur.
Earlier in January this year, Tsitsipas was defeated by Federer at the Hopman Cup in Perth. Across the country in Melbourne, the Greek had his revenge.
