(Reuters) - Highlights of the seventh day at the U.S. Open, the final Grand Slam tournament of the year, on Sunday (times GMT):
Third seed Roger Federer was barely tested in his fourth- round match against David Goffin, beating the Belgian 6-2 6-2 6-0 at Arthur Ashe Stadium to advance in 79 minutes.
Federer converted nine of 10 break points, won 19 net points and hit 35 winners (27 more than Goffin) to move into his 56th Grand Slam quarter-final.
Second seed Ash Barty lost 6-2 6-4 to China’s 18th seed Wang Qiang, who advanced to her first Grand Slam quarter-final by dispatching the French Open champion in 82 minutes.
Wang claimed victory on her third match point after Barty had saved two on her own serve, but 39 unforced errors by the Australian, who did not convert a single break point, saw her make an earlier than expected exit in New York.
Play began on Sunday in cloudy conditions with the temperature hovering around 22 degrees Celsius (71.6°F) and a forecast high of 25C, with rain expected later in the day.
