Felix Auger-Aliassime just dismantled Rublev 7-5, 6-3, 6-4 like it was nothing - and this is the same guy who was 1-7 against the Russian! The Canadian's mental game has completely flipped since his injury struggles. Watching him stay composed after getting broken early was pure class. Three years ago he was just a promising kid on Arthur Ashe, now he's back with that veteran ice-cold killer instinct. This quarterfinal run feels different - Felix looks like he finally believes he belongs with the big boys. Can he keep this magical run alive against de Minaur? #Sports #Tennis #USOpen
