Faces Garcia.
Caroline Garcia is next up for Gauff, who will face either Ons Jabeur or Ajla Tomljanovic should she overcome the US Open quarter-final debutant.
Australia's Tomljanovic followed up her defeat of Serena Williams with a 7-6 (10-8) 6-1 win over Liudmila Samsonova, snapping the Russian's 13-match winning streak and reaching her second career grand slam quarter-final in the process.
World number five Jabeur, meanwhile, made history by becoming the first North African woman to make the US Open quarter-finals in the Open Era.
She is the third woman from the African continent to do so, with South Africans Maryna Godwin (1968) and Amanda Coetzer (1994, 1996 and 1998) having previously achieved the feat. Jabeur defeated Veronika Kudermetova 7-6 (7-1) 6-4.
