This has been a very high quality match, but both players have thrown in poor games at the end of sets. Muchova at 4-5 in the 1st Osaka at 4-4 in the 2nd Muchova will serve for this set now.

Osaka broke back and then saved a few break points (with insane shots) to hold for 6-5. She'll be looking to shut the door right here.

2nd set tiebreak on Ashe. Muchova does seem to be moving a little better than she was earlier in this set, and the points are really not that long.

US OPEN QF: Naomi Osaka wins 6-4, 7⁷-6³ against Karolina Muchova Very good recovery after the poor game at 4-4, Osaka has been playing some very good tennis since Canada and moves into the Semifinals of a Grand Slam for the first time since the 2021 Australian Open.

Naomi Osaka back to world #14 in the live rankings

Sinner leads Musetti 6-1 This is frankly what we expected.

Sinner leads Musetti 6-1, 6-4 Musetti's serve kept this set close, but in the end flinched in the 4-4 game.

To explain how this match is going, after Sinner held serve for 2-0 in the 3rd after having saved 4 break points, a bunch of fans started to head for the exits and it held up play for a few seconds. 6-1, 6-4, 2-0 and this should be done shortly.

Amanda Anisimova will take on Naomi Osaka in the Semifinals of the US Open Definitely the marquee SF, it's interesting because Osaka was not playing as well as she is now in that 2022 season. I think I'll pick Anisimova despite Osaka being the favorite, but expecting 3 sets.

The only two men's tennis players to reach the semifinals at every Major this season 😯

US OPEN QF: Jannik Sinner wins 6-1, 6-4, 6-2 against Lorenzo Musetti Very routine tonight, Musetti serving lights out in the 2nd set was the only competitive moment. Sinner finally had a good 1st serve%. Great run for Musetti though, first ever QF at a hard court Grand Slam.

Djokovic vs Alcaraz will officially run at 3pm Friday, they will not be flipping them like they did last year. Sinner vs FAA at 7pm but could be later.
