Tennis prodigy Cori ‘Coco’ Gauff is not the only teenager turning heads in the sport.

Seventeen-year-old Caty McNally took down Christina McHale, the 2016 Japan Women’s Open winner, 6-3, 1-6, 6-3 on Thursday to punch her ticket to the Citi Open quarterfinals.

McNally is now the last American teenager remaining in the singles tournament after already reaching the semifinals in doubles with 15-year-old Gauff, which will be played Friday night. Hailey Baptiste, 17, lost in the second round on Wednesday.

“All the success that all the Americans are having,” McNally said, “that just drives every single person and shows them that they can do the same thing.”

At the start of the 2019 season, McNally was ranked No. 411 and has since cracked the Top 150. She won the ITF W100 event in Midland, Michigan and followed it up with a stellar performance on grass, advancing to the semifinals of the ITF W100 tournament in Surbiton, Great Britain.

The Cincinnati native then went on to qualify for her first main draw at Wimbledon in July.

McNally will face fourth seed Hsieh Su-wei for a chance to compete in the D.C. semifinals. For doubles, McNally and Gauff will square off against third-seeded Anna Kalinskaya and Miyu Kato.
