To tell the truth, among the four Grand Slam tournaments, the US Open is obviously the most loosely dominated event of the Big Three. In the past 12 years, as many as five non-Big Three men's singles champions have been presented, namely Del Potro in 2009, Murray in 2012, Cilic in 2014, Wawrinka in 2016 and Thiem last year.

There may be fans who are going to be angry again: Murray is a brick, where it needs to be moved; one moment it is a giant, the next it is expelled.
That's okay, if you don't care about the "Big Three" but the "Big Four" as a whole, in fact, the contrast between the US Open and the other three Major Slams is more obvious - also since 2009, the US Open has produced 4 champions outside the Big Four, and the other three Grand Slam tournaments combined, only two have been born. They were Wawrinka at the 2014 Australian Open and the 2015 French Open. So, the four eggs are still super powerful!
Whether it is Murray or Wawrinka, after being deeply injured, it is no longer what it used to be. Adding to the problem is the fact that the Big Three are also in a poor state.
Nadal, who did not play in the Olympics, came to North America for a hard-court season, losing to South African player Harris in the third round of the ATP500 tournament in Washington last week, and announced his retirement from the Rogers Cup Masters this morning. It seems that Nadal's left foot injury is indeed quite serious, and he also revealed that although he did not touch the racket for 20 days after the French Open to fully recover his body, once he was back in training, the obvious pain in his left foot made him unable to guarantee the intensity of training. Nadal was also unsure of his plans for the next competition, saying only that he needed to do a lot of checks before discussing with the team.
The other two giant stars, Federer, who has just spent his 40th birthday, retired two consecutive Masters tournaments, and the US Open became suspicious. Djokovic is preparing to parachute into the US Open, and not many people will be surprised by this, after all, after a long and successful half year, especially after the setbacks experienced in the Olympic Games, he urgently needs to rest; moreover, he has also practiced airborne Grand Slams in recent years and does not affect the direct victory of the championship. But it must be admitted that on the road to the Deyo's impact on the season Grand Slam, the US Open is his last but also the highest uncertainty threshold.
If this year's US Open really gives birth to a new champion, Medvedev, who is currently ranked No. 2 in the world, is of course very optimistic, last year's US Open top 4 and the Australian Open runner-up at the beginning of the year, have proved his hard strength, and in the process he has accumulated a lot of valuable experience in grand slam rounds. In addition, Zverev, Tsitsipas, Rublev, Beretini and Shapovalov are also the new generation of stars in the world's top 10.
As for defending champion Thiem, the situation is not too good either. Although the wrist protector has just been removed, it is uncertain when he will return to the field; even if he can return before the US Open, it will be difficult for him to mobilize his peak state in a short period of time. In addition, during this year's US Open, he will celebrate his 28th birthday, and it is difficult to be classified as a young player again!
