Emma Navarro achieved a remarkable comeback to defeat Paula Badosa 6-2, 7-5 in the U.S. Open quarterfinals, marking her first entry into a Grand Slam semifinal. After trailing 5-1 in the second set, Navarro won six consecutive games, a feat she attributed to maintaining her confidence and capitalizing on Badosa's nerves. This victory follows Navarro's upset of reigning champion Coco Gauff in the previous round and positions her as a strong contender for the title. She will face either Aryna Sabalenka or Zheng Qinwen in the semifinals. Navarro's journey in this tournament is particularly notable as she had never won a match in the main draw of the U.S. Open before this year. Her performance underscores her rapid rise in women's tennis, making her one of the few collegiate players to reach this stage at the U.S. Open since 1990.
