Just two years ago Genie Bouchard, who trains in Plantation, won the Wimbledon Girls' singles championship, and and on Saturday the 20-year-old Canadian will be playing for the adult version.

Two other South Florida teens are hoping to follow in her footsteps as Stefan Kozlov and Tornado Ali Black both reached the quarterfinals of the boys' and girls' singles and doubles draws respectively on Thursday.

The sixth-seeded Kozlov of Pembroke Pines knocked off the ninth-seeded Naoki Nakagawa of Japan, 6-3, 7-6 (2), as he won 84 percent of his first serves while committing just 12 unforced errors to his opponent's 24.

Kozlov, an Australian Open juniors finalist, hasn't dropped a set in his first three matches, and he's also into the quarterfinals of doubles as the top seed with partner Andrey Rublov. Kozlov, 16, will play the second-seeded Hyeon Chung, 18, of Korea in a quarterfinal on Friday.

The third-seeded Black, who resides in Boca Raton, dispatched Katie Boulter 6-1, 6-2 in a third-round match as she won 70 percent of her first serves (30 of 43) while converting five of six break points. Although Boulter had 20 winners to Black's three, the Brit also committed 37 unforced errors to Blacks' eight.

Black, 16, who split with the USTA before the French Open, is in London with no coach or family member because of finances. She will play Latvia's Jelena Ostapenko on Friday. Black is also seeded third in doubles and advanced into the quarters with partner Naiktha Bains of Australia.
