The second half of the boys’s quarter-finals wrapped up on Wednesday as Jannik Sinner rolled Lorenzo Musetti in straights to proceed his machine-like march by way of the draw, whereas Felix Auger-Aliassime battled previous Alex de Minaur in over 4 hours to achieve his first Grand Slam semi-final since 2021.
For Sinner, it was one other reminder of the hole between himself and the remainder: 91% of first-serve factors received and nil service video games dropped towards a top-10 opponent is the stuff of dominance.
For Felix, it was guts and nerves in equal measure, saving a set level within the second set and clawing again from 2-5 down within the fourth to make the final 4.
The wins arrange a semi-final on Friday that may see Sinner vs Auger-Aliassime, and Djokovic vs Alcaraz.

Felix Auger-Aliassime def. Alex de Minaur, 4-6, 7-6(7), 7-5, 7-6(4)

Felix Auger-Aliassime rallied previous eighth seed Alex de Minaur 4-6, 7-6(7), 7-5, 7-6(4) to achieve the US Open semi-finals on Wednesday, his second Flushing Meadows final-four run.
The twenty fifth seed saved a second-set tiebreak set level and received 13/17 tiebreak factors in a four-hour, 10-minute battle to make his second Grand Slam semi-final and first since 2021.
This was a nervy match from each gamers, with De Minaur all the time struggling to take his recreation to the subsequent degree on the latter phases of Slams and Felix additionally trying fairly tight.
Whereas I’m glad it didn’t because it was onerous tennis to observe, I’m undecided how this didn’t go 5 as ADM was forward in virtually each set, had a set level within the second set tie break, and had a 5-2 lead within the fourth however wasn’t in a position to capitalise, and he’s now 0-6 in Grand Slam quarterfinals.
Felix has had a reasonably good event with some good wins, and he fought properly right this moment, however I don’t see how he could be a issue within the semi-final.
Based mostly on his degree right this moment, I give him 6 video games, and if he can match Shapovalov’s efforts towards Sinner, that may be spectacular.

Jannik Sinner def. Lorenzo Musetti, 6-1, 6-4, 6-2

Jannik Sinner dominated tenth seed Lorenzo Musetti 6-1, 6-4, 6-2 to maintain his title defence trying extra doubtless by the day.
The World No. 1 received 91% of first-serve factors (42/46), saved 7 of seven break factors and and broke 5 instances in a two-hour rout.
I assumed Musetti was extra aggressive than the scoreline suggests, however he by no means fairly grabbed momentum, and on the large factors, Sinner simply stored him pinned deep behind the baseline, the place it’s an uphill battle.
Nonetheless to make the quarter finals on his worst floor after a piss poor run put up Roland Garros is a good efficiency.
Sinner is TennisGPT, and it’ll take a artistic genius to make him malfunction right here and there; solely Alcaraz is absolutely able to doing that.
