Our regular feature, The Base Line, returns this week as we look to keep you up to date with the relentless and fast-paced nature of the ATP and WTA Tours. Who were crowned champions, who struggled to make an impact, and what moment stood out recently in the tennis world?

Title winners

Starting in Basel, 19-year-old wonder kid Joao Fonseca claimed the second - and biggest - title of his very young career, as he claimed a comfortable 6-3, 6-4 over Alejandrova Davidovich Fokina, who continues to be arguably the best player on the ATP Tour never to have won a title.

The Brazilian was superb all week, also seeing off Giovanni Mpetshi Perricard, Denis Shapovalov and Jaume Munar on route to success.

As a result, Fonseca became the first Brazilian to lift an ATP 500 trophy, while also becoming the youngest Basel champion since 1989.

It has been a wonderful breakout year for Fonseca, and despite a bit of a dip in the middle of the season, he has now risen to a career-high 28 in the world rankings. 12 months ago, he was number 154.

Over in Vienna, it was another title triumph for world number two Jannik Sinner, as he overcame Alexander Zverev in a surprisingly tight final, 3-6, 6-3, 7-5.

It was the Italian's second crown in the Austrian capital, his 22nd overall, and fourth of the year, while cementing himself as the man to beat on indoor hard courts, with 21 straight wins.

Since his US Open final defeat to Carlos Alcaraz, Sinner has clearly improved his serve massively, which was a problem against the Spaniard on several occasions this season.

As well as that, he utilised the drop shot regularly against Zverev, confirming the fact that he is looking to add more strings to his bow. 

Wouldn't it be great to see another Alcaraz vs Sinner final in Paris this week?

On the WTA Tour, Belinda Bencic continued her remarkable comeback year, winning the title in Tokyo -where she also won her Olympic Gold medal five years ago.

The Swiss player eased to a 6-2, 6-3 over Linda Noskova to pick up a 10th career title, and her second title of 2025.

Returning from maternity leave, Bencic was ranked 421st in the world at the start of the year. She is now up to 11th in the world. It has been an amazing return to tour for her.

Her excellent backhand was in fine touch all week, helping her also defeat Karolina Muchova and Sofia Kenin

Special mention to Elena Rybakina, too. Her run to the semi-final meant that she overtook Mirra Andreeva to become the eighth player to qualify for the WTA Finals.

The Kazakh withdrew from her last-four clash with Noskova due to not being fully fit, but in truth, her job was already done. She had eyes on qualifying for Riyadh, and she achieved that.

Finally, Ann Li won her second WTA Title, and her first since 2021, after defeating Lulu Sun 7-6(6), 6-2 in the Guangzhou final.

With her victory, she became the eighth American to win on the WTA Tour this season.

Biggest strugglers

Andrey Rublev's woes continued with an opening-round loss to Cameron Norrie in Vienna, meaning that he has now lost five consecutive matches!

The Russian has endured a tough year in general, as he searches for the form that made him such a consistent figure and two-time Masters champion. However, right now, he is absolutely miles off that level.

Ben Shelton continues to hunt for top form after his heartbreaking injury at the US Open, suffering a last-16 defeat to Munar in Basel, following on from his opening round exit to David Goffin in Shanghai.

The American was building so much momentum in the last few months, but that seems to have stalled a little bit, solely due to fitness problems. However, he remains in a strong position to qualify for his first-ever ATP Finals.

In Guangzhou, top seed Jessica Bouzas Maneiro - who has actually enjoyed a really good 2025 - fell at the first hurdle, as she was defeated by finalist Sun.

Standout moment

The standout moment last week actually came off the tennis court, as it was announced that the ATP  had come to an agreement with Saudi Arabia's Public Investment Fund to host a new Masters 1000 event in the country, expanding the category for the first time in its 35-year history.

The event in Saudi Arabia will launch in 2028, making it the 10th Masters event on tour.

In truth, it was a really seismic announcement. Saudi Arabia have been really trying to get their claws into tennis for a while, with the WTA Finals and Next Gen Finals being hosted in Riyadh and Jeddah, respectively, while the exhibition tournament, the Six Kings Slam, began last year.

But now they finally have their very own tournament in the sport. Despite their serious human rights issues and the fact that players on tour have been asking for the people in power to trim down the calendar, the ATP have bulked up the tour instead.

An interesting decision, and it simply illustrates that money talks.

Best rallies

Veteran Stanislas Wawrinka and Sinner produced two unstoppable forehand winners last week, demonstrating the remarkable power and quality both superstars possess.

Upcoming events

The final Masters event of the year is underway today in Paris, which is being hosted in a new venue! Alcaraz and Sinner lead the field, and it is the last major opportunity the world's best players will get in their goal of qualifying for the ATP Finals.

Meanwhile, in the penultimate week on the WTA Tour, tournaments head to Hong Kong, Jiujiang and Chennai.
