Though ostapenko

New York: The 19-year-old Coco Gauff of the United States stormed past No. 20 seed Jelena Ostapenko to seal her maiden entry into the women's singles semifinals at the US Open here on Tuesday.

Gauff came up with a dominant display as she defeated Ostapenko 6-0,6-2, extending her win streak to 10 matches on Tuesday. Gauff thus became the first American teenager to reach the semifinals here since Serena Williams did it in 2001.

It was a battle between two form players. Ostapenko had caused a major upset in the fourth round by beating world No. 1 Iga Swiatek. Gauff has now won 16 of 17 matches in 35 days.
