LONDON -- Sloane Stephens of the U.S. reached her second Grand Slam quarterfinal of the year, beating 19-year-old Monica Puig of Puerto Rico 4-6, 7-5, 6-1 Monday at Wimbledon.
The 17th-seeded Stephens is the last American singles player left at the grass-court tournament.
She finished her 2-hour, 4-minute victory shortly after defending champion Serena Williams' 34-match winning streak ended with a three-set loss to Sabine Lisicki.
For the first time in 101 years, no men representing the U.S. even made it to Wimbledon's third round.
Stephens, who is 20, eliminated Williams in the quarterfinals at the Australian Open in January to reach her first career major semifinal.
Next for Stephens in her second appearance at Wimbledon is a match against No. 15 Marion Bartoli, the 2007 runner-up, or 104th-ranked Karin Knapp.
