Stefanos Tstsipas defeated Daniil Medvedev to reach his third consecutive Grand Slam semi-final. The 22-year-old won 6-3, 7-6 (7/3), 7-5.
Tsitsipas has the most wins on the ATP tour this season (38) and won clay-court titles at Monte Carlo and Lyon.
Alexander Zverev on the other hand defeated Spain's Alejandro Davidovich Fokina 6-4, 6-1, 6-1 in a 96-minute match to advance to the French Open semi-finals.
Zverev's French Open had a wobbly start when the 24-year-old dropped two sets in his opening game versus Oscar Otte. However, he fought back to claim a five-set victory and has not dropped a set since. The 2020 US Open runner-up now heads into his third semifinal in the past five Slams.
“The Grand Slams, they’re still a different animal. … You got to learn how to play them, as well. Very rarely does anybody come in and, all of a sudden, perform his best at Grand Slams. Yes, we’ve seen Rafa do it, but Rafa is sometimes not human,” Zverev said after winning the quarter-final.
