Who can stop world No. 1 Jannik Sinner or No. 2 Carlos Alcaraz at the US Open?

The GIST: Over on the men’s side, the two top players in the world appear to be on a collision course to their third Grand Slam final showdown of the year — but it’s not over ’til it’s over. Let’s take a look at how reigning champ and world No. 1 Jannik Sinner and No. 2 Carlos Alcaraz are handling their US Open draws, plus the underdogs who just might shake things up.

👏 Dominant is an understatement: Both Sinner and Alcaraz have made light work of their opponents thus far: Alcaraz, cheeky and quick as ever, has yet to drop a set and already has his semis spot locked in, while Sinner’s big serve and consistency have yielded only one set thus far.

• The defending champ faces his Italian countryman, No. 10 Lorenzo Musetti, a player he’s never lost to, in tonight’s primetime QF. Sinner and Alcaraz appear destined for Sunday’s title match…but let’s not get too far ahead of ourselves.

🔧 So which contender has the best shot at an upset?: How about four-time US Open winner No. 7 Novak Djokovic, who secured himself a semis date vs. Alcaraz with last night’s four-set win over No. 4 Taylor Fritz, the 38-year-old’s 11th win over the American in 11 matches.

• And on the other side of the draw, Canadian No. 27 Felix Auger-Aliassime, the lowest ranked men’s player remaining, could cause some trouble if he can advance past No. 8 Alex de Minaur in today’s 11:30 a.m. ET QF.
