Dominic Thiem achieved a monumental victory in his tennis career by winning the 2020 U.S. Open final against Alexander Zverev, despite the match being played in front of empty seats due to COVID-19. The atmosphere was stark, with only camera shutters and sparse applause marking the moment. Thiem faced immense pressure, having lost three previous Grand Slam finals, including two to Rafael Nadal and one to Novak Djokovic. Initially, he struggled, losing the first two sets before overcoming his nerves to secure the title. Reflecting on the match, Thiem noted the odd feeling of competing without the typical crowd energy and acknowledged the weight of expectation in finally winning a Grand Slam. His victory marked a significant shift in men's tennis, breaking the grip of the 'Big Three' players who had dominated the sport.
