Jil Teichmann only won the right to attend Cincinnati Masters 2021 with a special ticket but created the biggest shock in the US tournament since the beginning of the tournament, and could also be the most memorable victory in the Swiss player's career.
Naomi Osaka started not bad at the first set. Japanese players make good use of the opponent's mistakes to have 2 breaks and lead 3-0. Teichmann tried hard in the next time but still lost 3-6.

Suddenly happened in set 2 when Naomi Osaka left the opponent 74 steps less than the WTA ranking more overwhelming. Teichmann did a good job in the gaming games and did not face any break-point. Meanwhile, Osaka broke a lot and lost 2 breaks. The final ratio of set 2 is 3-6 in favor of Teichmann.
Set Set 3, Naomi Osaka made many double serve errors and let the opponent rob the break 2 times. Teichmann continued to win 6-3 in the decision set to complete the spectacular backward before the world's No. 2 player.
Stopping in the third round, Naomi Osaka only pocketed the $ 24,000 bonus. Earlier, the Japanese player announced he would win all his bonuses to support the rescue of the earthquake in Haiti on August 14, killing more than 1,900 people.
This has failed the second largest in a row of Naomi Osaka in less than 1 month. Earlier at the Tokyo 2021 Olympic Games, Naomi Osaka also failed in the third round before the 41st player, Marketa Vondrousova.
