US Open underdogs Osaka, Auger-Aliassime storm into quarter-finals

The U.S. Open's Labor Day Monday morning session belonged to the underdogs, as Naomi Osaka and Felix Auger-Aliassime delivered commanding performances that carried them back to Grand Slam quarter-finals after years in the wilderness.

Auger-Aliassime delivered his own statement with a composed 7-5 6-3 6-4 victory over 15th seed Andrey Rublev, reaching his first major quarter-final since the 2022 Australian Open after battling through injuries and confidence struggles.
