The No5 in the main draw Stan Vivrinka had to walk a difficult path, but finally succeeded to qualify for the third round of the US Open. The Swiss won with 7:6 (2), 7:6 (4), 7:6 (6) over the teenager from Korea - Chung Heyong.
The 19 years old Chung managed to hamper his illustrious rival from the first to the last point of the match and deservedly left the court under the applauses of the audience.
For Wawrinka the evening was certainly special, because this victory for him was under No100 in Grand Slam (100 wins and 40 losses). Earlier in the season, Stan won his second Grand Slam title, when triumphed in "Roland Garros".
The 30-year-old Wawrinka shows great concentration in the major tournaments by soccer predictions of the season, as he doesn`t drop out before the quarter-final stage.
In a dispute for a place in the second round of US Open, Wawrinka will face Ruben Bemelmans, who beat Jack Sock after walk over of the American.
