"I've always valued the history of tennis and the example set by those who came before me," Federer said. "To be recognized in this way by the sport and by my peers is deeply humbling."

The Belgians ended a four-tie losing streak against the 10-time champions Tuesday in Bologna.

The 2025 year-end No. 1 will spend the next two weeks healing a hamstring injury to return for a series of matches in Newark and Miami.

The Spaniard and American have dueled at the past two editions of the men's team event.

Garin won in Montevideo while Jan-Lennard Struff lifted the trophy in Lyon. Plus, a preview of the final Challenger events of the season.

"The medical recommendation is not to compete," the 22-year-old Spaniard wrote on social media.

With the ATP’s Top 2 absent, there’s room for an unlikely hero.

De Minaur and Joint will suit up for the host nation, as Mboko, Mensik and Lys are each set to debut.

Things may be changing soon for the self-described "full-time tennis player, part-time broadcaster."

Retired doubles specialist Butorac was the tournament director for this year's new US Open mixed doubles event, as well as for the 2022 Cincinnati Open.

The head-to-head between Sinner and Alcaraz blossomed into full-blown dominance this season.

It'll also be his record-breaking 17th Top 5 finish.

The now-18-year-old helped Belgium, without Elise Mertens, upset host Germany in the decisive match.

The 2026 chapter of this generational rivalry is already loading.

Sunday showed the Italian's adjustments were a success in his season finale at Turin.

He's the first man this century to achieve the feat, and the second man ever after Ivan Lendl in 1985 and 1986.

The Italian improved to 6-10 in their series after triumphing at the Nitto ATP Finals to cap his 2025 season.

The world No. 2 saved a set point before emerging victorious Sunday in Turin, 7-6 (4), 7-5.

Which player will leave 2025 with three of the five biggest titles of the year, and which one will leave with two?

"Playing against Jannik on indoor court is one of the best or most difficult challenge[s] that we have in tennis right now," he said.

The Spaniard is 4-1 in their season series; the Italian has won 30 straight indoor matches.

The 23-year-old, already a WTA title-winner, is on the brink of something big—not just for herself, but for Turkish tennis.

The Spaniard eliminated Auger-Aliassime, 6-2, 6-4, in Saturday's second Turin semifinal.

"The tennis season is long, you have a lot of up and downs. For me there were not many ups," he said after losing to Felix Auger-Aliassime.

He went into the US Open ranked No. 27. Now, a little over two months later, he'll be a Top 5 player for the first time.

At 24, he's the youngest player EVER to achieve the feat.

The Canadian owned their head-to-head early, but the Spaniard has since posted four consecutive straight-set wins.

The Canadian sealed a spot in the semifinals against Carlos Alcaraz with a 6-4, 7-6(4) winner-take-all round-robin victory.

Lys is set to finish the season inside the Top 40, making her the top-ranked German.

The Spaniard is set to headline next week's event in Bologna, while his rival won't seek a three-peat with the host nation.

Will the 13th time finally be the charm for the underdog Aussie against the defending champion?

“I’m really grateful for everyone,” said the Spaniard after clinching the year-end top spot for the second time in his career.

And no other man will even come close to that this year.

The Australian was a picture of despair after a defeat to Lorenzo Musetti, but staged an unlikely resurrection in more ways than one.

Having also done it in 2022, the 22-year-old is now the second-youngest man ever to finish TWO years at No. 1.

Lys is joined by 19-year-old Tessa Brockmann, and will face teams from Turkey and Belgium.

Either the German or Canadian will advance out of the Bjorn Borg Group with the home favorite.

“If you want to win a big title…you're going to have to beat one of 'em, maybe both of 'em,” the American said in Turin.

His year started with a surprising cut—but over time, the ATP Finals qualifier brought back a more familiar look.

While his season will officially end in the round-robin phase of the ATP Finals, Shelton said there's still "a lot of things to be happy about" in 2025.

He also keeps his hopes of finishing the year at No. 1 alive.

The top-ranked Italian woman proved a popular figure as she took in the action between Alex de Minaur and compatriot Lorenzo Musetti.

All four players are in contention to advance out of the Jimmy Connors Group.

The Canadian rallied from a set down to stay alive in the Björn Borg round robin group.

The two tennis stars kicked off their vacation with a lip-sync to a 4 Non Blondes-Nicki Minaj mashup.

The former world No. 68, now ranked No. 275, hopes to compete in the Australian Open Asia-Pacific wildcard playoff later this month in Chengdu.
