3 Amanda Anisimova will clash in an All-American semifinal at the China Open in Beijing. Gauff, the defending champion, advanced to the semifinals for the third straight year and improved to 14-1 in Beijing with an 88-minute win against the hard-hitting Lys. Gauff, 21, and Anisimova, 24, have met twice before in tour-level competition but never on a hardcourt. Anisimova needed two hours and 47 minutes to finish off a win that secured her first-ever ticket to the WTA Finals in Riyadh. Anisimova saved 11 of 14 break points against Paolini, who rallied from a 5-3 deficit to take the opening set.
