NEW YORK (Reuters) -Twice Wimbledon champion Petra Kvitova bade an emotional farewell to professional tennis on Monday after her first-round defeat at the U.S. Open, saying she was most proud of her resilience and major triumphs during a memorable two-decade career.
The 35-year-old Czech returned to competition earlier this season following a 17-month maternity break and announced ahead of Wimbledon that she would call time on her career at the end of the year's final major in New York.
