In the tournament's first quarter final, almost every ball was as entertaining as even where the baseline game dominated.
After a strong start by the Argentine Schartzman, Dominic Thiem had managed to pinch the second set and then managed to get what turned out to be a match-decisive grip until the fourth.
During the match, the two players had managed to break each other's server, but when Thiem had the decisive position, Schwartzman kept the press without giving Thiem a single match ball.
In tiebreak, he then saved the match to 2-2 and when the fifth and decisive started, there was never really any talk about who was the most energetic after four and a half hours.
When the semi-finals are won, the Argentine Schwartzman will either have to face the twelve-time French Open champion Rafael Nadal or the Italian teenager Jannick Sinner.
