Cincinnati native Caty McNally and fellow American Coco Gauff reached the Australian Open women's doubles quarterfinals with a 7-5, 6-3 upset of ninth seeds Alexa Guarachi and Desirae Krawczyk.
Up next for McNally and Gauff: No. 4 Nicole Melichar and Demi Schuurs.
Last September, McNally, 19, reached the third round of the U.S. Open women's singles with a second-round upset of 21st seed Ekaterina Alexandrova.
Last January - in her Australian Open women's singles main-draw debut as a qualifier - McNally upset Samantha Stosur.
In Aug. 2019, McNally won a set at the U.S. Open against Serena Williams - the first time in Williams' remarkable career that she lost a set in the second round of the tournament.
McNally, from Madeira, trained at The Club at Harper's Point - where her mother, Lynn, has coached.
