Coco Gauff dealt just fine with the heat, the humidity and a big-hitting opponent to defeat Jelena Ostapenko 6-0, 6-2 on Tuesday, becoming the first American teenager to reach the final four at Flushing Meadows since Serena Williams in 2001.
This was the 16th victory in her past 17 matches for Gauff, who will face No. 10 Karolina Muchova of the Czech Republic on Thursday.
Gauff’s first-round exit at Wimbledon in July feels like ages ago. Her best showing at a major was making it to the final at Roland Garros last year.
