Joao Fonseca crowned an incredible week by winning the Next Gen ATP Finals title, defeating Learner Tien 2-4, 4-3(8), 4-0, 4-2. The Brazilian was the youngest player in the draw and ranked lowest (No. 145), but managed five consecutive victories, including wins over No. 20 Arthur Fils and No. 48 Jakub Mensik.
The two players had already met in the Roland Garros quarterfinals (won by Tien) and in the 2023 US Open final, where the Brazilian came out victorious. Just three days earlier, Fonseca had again defeated Tien in the Round Robin stage with a dominant 4-0, 4-0, 1-4, 4-2 scoreline.
Fonseca outlasts Tien in thrilling final
In the first set, Tien showed clear intent to fight for the title, even though Fonseca’s exceptional level this week made him the favourite. The American started with an early break in the opening game, having two break point opportunities, and quickly took the lead. With 81% first serve and 85% points won on the first serve, the 18-year-old Brazilian won only four return points, which wasn’t enough to recover the deficit. Tien closed the first set 4-2 after 19 minutes.
When the second set began, both players struggled with their first serves, and each had break opportunities. However, the set remained close until a tense tiebreak. Both players dropped their first two points on serve, leading to a 2-2 tie. Fonseca took a 6-3 lead but couldn’t close out the set. Tien had a set point, but Fonseca wasted four chances before finally taking the set 4-3(8).
Despite the tightness of the previous set, Tien started the third set unfocused, while Fonseca stepped up his level. He won 11 consecutive points to quickly go 3-0 up with two breaks of serve. The Brazilian won 16 of the 19 points played (84%), enough to take the lead for the first time in the match and set up a fourth set where he would seek to close out the match.

- Vukov is doing this to Lena... AGAIN!!!!! WTA's autonomous collective should be dismantled for allowing Vukov to re-emerge from his hand-slapping suspension. Just ask WTA employees how that's been going lately as they witness his continued verbal abuses. Women's Pro Tennis should start over.
mandoist08-11-2026 - Can't help but suspect Vukov is back to his old self again. Thank you, WTA. Perhaps you can give them a "Battling Couple of the Year Award 2026" ??mandoist08-11-2026
- Wtf? Why is there no reason? And what about the men's?Bel08-11-2026
- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.mandoist06-11-2026
- Enough of her bullshit. Go marry someone.mandoist06-11-2026
- Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.mandoist05-11-2026
- Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.mandoist05-11-2026
