Serena Williams, former world No. 1 and seeded 17th in the tournament, maintained her good performance at the US Open to advance to the third round by winning 6-2, 6-2 against German Carina Witthoeft.
The youngest of the Williams sisters needed only 67 minutes to seal the victory on Wednesday as she attacked her German rival with 13 aces, 30 total winners and 15 unforced errors in the second match she ever had against Witthoeft, the world No. 101, with a score of 2-0 in the series, reports Efe news.
The next rival of the six-time champion of the US Open will be her older sister Venus, 16th-seeded and two-time winner of the last Grand Slam of the year, where she beat the Italian Camila Giorgi 6-4 and 7-5.
