Djokovic lowered Tien in the first round of the United States

Djokovic is not really overwhelming despite winning after three sets, when he experienced many difficult games before the 19 -year -old opponent. In the second set, the number one former world made 20 errors. At this time, Nole struggled with physical condition despite favorable conditions in the evening.

The difficulty of Djokovic comes from Tien's determination to return to Set Hai. After losing the first set in 20 minutes, the Vietnamese-original talent was shocked, bringing the two to the tie-break series and lost only after 80 minutes of fighting. This is the impressive set of Tien, the 50th person at the 50 ATP but there have been four wins against the top 10 world since the beginning of the year. Tien's durable play after Baseline is effective against Djokovic who is older and moving less flexibly than usual. At the beginning of this set, the Grand Slam record was falling in the situation of returning the ball, partly affecting his runs later. In front of the ball or the most history, Tien wanted to put the ball into a difficult position in the second delivery but this was a double -edged sword, causing him to lose beats and often have to save the game. In Set Ba, although soon took advantage of the break-point successfully in the first game, the 19-year-old talent lost all the four games delivered, could not save any break-point. Djokovic is also unstable, but still won after 36 minutes. "We have played the opposite sets and fortunately the more I fought me the better. I couldn't complain with such beginning at Grand Slam, where the opponents were very unpredictable ".. Earlier, he seemed to have problems in his hips and often pulled the racket back many times, a manifestation of wanting to breathe more oxygen. At the age of 38, physical is a serious problem for Nole at each Grand Slam. He gave up in the semi -finals of Australia's expansion early this year due to injury, then lost to Jannik Sinner quickly in the next two semi -finals in Paris and London because he could not keep up with the enemy. Some seeds on the lower branch of Djokovic also go on after the opening day, Jakub Mensik, Ben Shelton and Taylor Fritz.
