Day six of the 2025 Nitto ATP Finals locked in the ideal semi-final lineup as Jannik Sinner and Felix Auger-Aliassime both sealed their places in the last four with straight-sets wins.
Sinner continued his indoor dominance by dispatching Ben Shelton to finish a perfect 3–0 in the Bjorn Borg Group, while Auger-Aliassime completed a remarkable turnaround to beat Alexander Zverev and reach the semi-finals for the first time.
The results mean Sinner and Alcaraz avoid each other in the semi finals and it’s hard to see anything but a Sincaraz showdown on Sunday.

Jannik Sinner (2) def. Ben Shelton (5) 6-3 7-6(3)
Jannik Sinner capped a perfect 3-0 round-robin at the 2025 Nitto ATP Finals with a 6-3, 7-6(3) victory over Ben Shelton in Turin on Friday, extending his indoor winning streak to 29 matches and ending the American’s debut campaign.
Sinner was already qualified, so the only thing he was really playing for was to keep momentum and the extra cash on offer for a round robin win (and the potential of the undefeated champion prize), so he wasn’t at his best but his serve looks like it’s come on leaps and bounds since the USO and he faced just one break point.
Key Match Highlights:
First Set (6-3, 38 minutes): Sinner overcame an up-and-down serve to break Shelton midway through, capitalising on the debutant’s nervous start. The Italian absorbed early pressure and closed out efficiently.
Second Set (7-6(3), 52 minutes): Shelton surged with explosive serving, dropping just two of 18 service points through the first nine games and saving a match point at 4-5. But Sinner dominated the tie-break with clean net approaches, winning 7-3 after a series of winners. He improved to 8-1 in their head-to-head (eighth straight win).
Post-Match Quotes (Sinner):
When you come here and win all three round-robin matches, you have to play at a very high level, which I’ve done. Serving very well in important moments has brought me to this point. It was a very special day playing in front of the home crowd, and against Ben it’s always a tough challenge. When he comes up with a huge serve, you cannot do a lot, so you have to accept it. My mental aspect [has been] great until now, so let’s see what’s coming. Sinner on his win.
Broader Context:
- Match duration: 1 hour, 30 minutes.
- Eighth straight Nitto ATP Finals win without dropping a set; tops Bjorn Borg Group.
- Potential blockbuster final vs. Alcaraz if both advance (Alcaraz already No. 1).
- Next: Saturday SF vs. Alex de Minaur.

Highlights
Felix Auger-Aliassime (8) def. Alexander Zverev (3) 6-4 7-6(4)
Felix Auger-Aliassime completed a stunning group-stage turnaround with a 6-4, 7-6(4) victory over Alexander Zverev in Turin on Friday night, securing second place in the Bjorn Borg Group behind Jannik Sinner and advancing to the semi-finals for the first time.
After his injury woes against Sinner, I wasn’t even sure Felix would play any further part in the event, but he’s pulled off back-to-back wins and finds himself in the last four.
As for Zverev, he played like a guy who knew he wouldn’t be beating Alcaraz in Saturday’s semi-final, and his whole game lacked conviction. Plenty of nice points but when it came to the crunch his powder puff forehand was his shot of choice and it again proved costly.
Key Match Highlights:
First Set (6-4, 48 minutes): Auger-Aliassime withstood Zverev’s pressure, saving break points at 30/40 in the fifth and ninth games. He broke in the 10th at 5-4, earning four set points from 0/40; Zverev saved three, but a stunning cross-court forehand on the fourth sealed the opener.
Second Set (7-6(4), 79 minutes): Both players faltered on consistency, with Zverev gesturing frustration to his team and Auger-Aliassime missing three earlier break point chances. In the tie-break, the Canadian earned consecutive mini-breaks from 4/5 via Zverev errors to close out decisively. Zverev now leads their head-to-head 6-4 overall, but Auger-Aliassime sweeps 2025 (also US Open R3 win).
Post-Match Context:
- Match duration: 2 hours, 7 minutes.
- 50th tour-level win of 2025; second Canadian in ATP Finals SFs (after Milos Raonic, 2016).
- Chasing fourth title of season (Adelaide, Montpellier, Brussels); Tour-leading 85 indoor wins since 2020 (5 ahead of Sinner).
Post Match Quotes (Auger-Aliassime):
This is a high-value tournament for players. It’s like a grand finale and when you have a look at the list of champs there have been many No. 1s. You want to be in the final but I’ll have to go through a great player to do that. I will take my chance if I have it. It was a great first set. He was getting a few chances but I came up with big serves to save them. The first set was very solid and the start of the second set was, too. I had a lot of chances. When that happens you need to focus on the present but you’re aware of missed opportunities, so the match got a little tense from that moment. But I was able to hold serve and in the tie-break it was tight till the end. Auger-Aliassime on his win.
Broader Context:
- Auger-Aliassime (2-1) tops Zverev (1-2) for SF spot; Shelton (0-3) eliminated.
- Next: Saturday SF vs. Carlos Alcaraz (top seed, 3-0 in group).
