Williams sisters, Murray, del Potro seek QF spots at US Open
NEW YORK (AP) Juan Martin del Potro, Andy Murray and the Williams sisters are among those seeking to book their spots in the quarterfinals on Labor Day Monday at the U.S. Open.
Del Potro, the 2009 champ who has won over fans with his comeback from left wrist surgeries, takes on eighth-seeded Dominic Thiem, who broke into the top 10 this year after reaching the French Open semifinals.
The No. 2-seeded Murray, who is hoping to add Flushing Meadows to his Wimbledon and Olympic titles this year, takes on 22-seeded Grigor Dimitrov. And third-seeded Stan Wawrinka, who saved a match point in a five-set win Saturday, faces Illya Marchenko.
Among the women's highlights are back-to-back afternoon matches on Ashe with the Williams sisters. Sixth-seeded Venus is on first against 10th-seeded Karolina Pliskova, who is in the round of 16 at a major for the first time. Then top-seeded Serena meets 52nd-ranked Yaroslava Shvedova.
Fourth-seeded Agnieszka Radwanska is in the nightcap on Ashe, taking on 92nd-ranked Ana Konjuh
Another roof-free day is expected weather-wise, with partly cloudy skies and highs in the low 80s.
