Filip Cristian Jianu: From ITF Grind to Challenger Consistency
Filip Cristian Jianu, 23, has 13 ITF titles and a career-high No. 210; he aims to break the Top 200
At 23, Filip Cristian Jianu has built steady momentum on the ATP Challenger circuit. The 1.80-meter right-hander from Bucharest has won 13 ITF World Tennis Tour titles, five of them last year, and reached a career-high ranking of No. 210 in June 2025. Once as high as World No. 5 in juniors and a 2019 Boys’ Australian Open semi-finalist, Jianu is concentrating on converting that junior pedigree into reliable results at the professional level.
His preferred surface is clay, though he adapts across courts. “I actually like faster clay courts and slower hard courts,” he says, describing a game based on precision, timing and point construction.
The jump from junior success into pro-level tournaments has demanded persistence. “One of the most challenging parts is getting into the big tournaments,” he explains. “For a player like me, coming from Romania, we don’t have that many opportunities to play in big tournaments. That’s easier for players from Italy, France or Spain, where so many Challengers and ATP events take place.
“I had to start from 15K tournaments on the ITF World Tennis Tour, which is not easy. You have to grind every week in order to gain some points. On the other hand, when you have a wild card into a main draw of a bigger tournament, you will earn the same number of points from a single match. So, it takes a bit more time to rise up the rankings. You cannot skip stages.”
He contrasts levels succinctly. “The difference between ITF events and ATP Challengers is the ball speed,” he says. “At Challengers the guys try to take the balls early and try to be offensive. On the ITF World Tennis Tour, it is more of a physical battle. There are less free points, and the opponent is waiting for your mistake. It is a different kind of tennis. The ball change is also different at nine and 11 games compared to seven and nine. You can feel it. The game at Challengers is faster and you need to be quicker and more aggressive if you want to win.”
“I had a bit of a rough period mentally,” Jianu admits.
I was struggling outside the court and wanted to play more matches. I wanted to find my rhythm and the joy for tennis again.
He has stayed based in Bucharest to retain stability. “I have been based in Bucharest for a while,” he says. “I prefer to be at home between tournaments. I have a good group of coaches and training partners. We are pushing each other every day. It is a solid base for me.”
Financial strain remains a challenge. “That’s a main issue,” Jianu says candidly. “We don’t get any support and it’s tough for us to find any sponsors.
We have to do it by ourselves. It’s not easy as you always have to look at the price and need to make some sacrifices to be able to travel. You really need to pay attention at every expense.
That’s why the recent growth of tournaments in his home country has been so important. “They started in the last couple of years,” he says. “This is very important for us Romanian players. We can play at home, saving money. Then, we have the support from the home crowd.
“We also have the ATP Tournament in Bucharest. I was awarded a wild card and won my opening round match against Nishesh Basavareddy, which gave me valuable ranking points. That helped me a lot. If they were more tournaments like those, we would see many more players from Romania coming up.”
The season brought milestones: a first Grand Slam appearance in Australia, a main-draw win at Roland Garros and reaching the third round of Roland Garros qualification, plus competing in Davis Cup. “I played my first Grand Slam in Australia,” he reflects.
“In Roland Garros I managed win my first match and reached the third round of the qualification, which was a very nice experience for me. And winning the ATP match at home was very enjoyable as well as competing in Davis Cup. My year could have been better, but there were a lot of highlights.”
Off court, he keeps routines simple. “During a tournament week I watch some TV series or play Romme,” he says.
“Right now, I am watching the Vampire Diaries, which is an old school show, but I like to pick a series, which you can watch for many hours. When I am at home, I enjoy having a nice dinner and going for a walk. I don’t really follow any other sports closely.”
His target is specific and immediate: “I want to break the Top 200 by the end of the year.”

Sinner’s serve numbers reveal a mixed picture despite his dominance
Sinner’s serve stats show elite power, but his first-serve percentage still leaves room for growth.
Jannik Sinner’s serve has long been viewed as a major part of his rise to the top of the men’s game, yet the numbers from the past year tell a more complicated story.
The world No 1 adjusted his service motion shortly before he began establishing himself as a leading force on the ATP Tour, and that weapon stood out again when he defended his Wimbledon title earlier this month.
After losing the US Open final to Carlos Alcaraz last September, Sinner made it clear that he wanted more variety and consistency on serve. His own words at the time showed how deliberate that change was:
“I can say that I’m gonna become a better tennis player and I’m gonna change a couple of things on the serve, just small things, but, they can make big differences and then we see how it goes,” said Sinner. after that defeat against Alcaraz in New York.
“I’m looking forward to play these matches again, something new is now that I’m not No 1 anymore. Now you chase, it’s different.
“Maybe I will lose some matches from now on, but I will try to do some changes, trying to be a bit more unpredictable as a player and because I think that’s what I have to do, trying to become a better tennis player.”
Even with his strong recent run, the ATP Tour figures for the last 12 months show that there is still work to be done in one area. Sinner ranks 35th in first serve percentage at 63.8%, well behind Alexander Zverev, who leads the list at 72.5%.
The Italian, however, is far more dominant once the first serve lands. He leads the tour in service points won at 80.9%, just ahead of Reilly Opelka on 80.8% and Taylor Fritz on 79.7%.
He also tops service games won at 92.9%, underlining how difficult he is to break. Opelka follows on 90.6%, with Ben Shelton third at 90.4% and Alcaraz at 89.9%.
One remaining area is ace production. Sinner is 27th in that category with an average of 8.2 per match, while Opelka leads with 18.5, followed by Giovanni Mpetshi Perricard on 15.1 and Fritz on 14.1.

Sinner climbs to No 4 on all-time prize money list after Wimbledon defence
Sinner’s Wimbledon defence lifts him to No 4 on the all-time prize money list in 2026.
Jannik Sinner’s successful Wimbledon title defence brought more than another major trophy. It also lifted the Italian to No 4 on the all-time career prize money list.
Before Wimbledon 2026, Sinner sat at No 6, with Novak Djokovic, Rafael Nadal and Roger Federer occupying the top three spots and Alexander Zverev and Carlos Alcaraz positioned above him. Zverev had recently passed both Alcaraz and Sinner after his French Open run, but the order shifted again once Sinner collected $4,830,756 (£3,600,000) for his latest Wimbledon triumph.
That result leaves Sinner close to becoming only the fourth player to move beyond $70m in career prize money. He has already earned $11,620,364 in 2026 and is on track to break the $20m barrier for the first time in a season.
His rise has been rapid. Last year, he took in $19,120,641, a total that included a record $5,071,000 for winning the ATP Finals undefeated. He finished second on the 2025 earnings list behind Alcaraz, who made $21,354,778, after leading the way in 2024 with $19,735,703.
At the end of the 2024 season, Sinner stood on $37,238,688. Since the start of the 2025 campaign, he has added another $32,347,873. From just $36 in prize money in his first professional year, he now sits on $69,586,561.
Zverev is fifth with $68,392,312, while Alcaraz is on $64,997,598 after not adding to his tally since April because of injury. Andy Murray has fallen to No 7 on $64,687,542, with Daniil Medvedev eighth on $52,192,594. Djokovic, Sinner, Zverev, Alcaraz and Medvedev are the only active players to have passed $40m.
Djokovic remains far ahead in first place with $194,656,816, including $3,000,801 earned in 2026. Nadal is second on $134,946,100 and Federer third on $130,594,339.

Auger-Aliassime Reaches Career-High No. 4 After Breakthrough at Roland Garros
Auger-Aliassime rises to No. 4 after best Roland Garros run, tying second-highest Canadian rank. Now
Felix Auger-Aliassime moved to a career-high No. 4 in the ATP rankings following his deepest run at Roland Garros, where the 25-year-old reached the quarterfinals for the first time before losing to eventual finalist Flavio Cobolli. The result completed a personal Grand Slam milestone: having previously reached the quarterfinals or better at the Australian Open, Wimbledon and the US Open, he became the first Canadian man to reach the quarterfinals or better at all four majors in his career.
The rise from No. 6 to No. 4 surpasses his prior best of No. 5 and places him tied for the second-highest-ranked Canadian in ATP or WTA rankings history. The only other Canadians to reach the top four are Milos Raonic and Bianca Andreescu. Raonic went as high as No. 3 in 2016, following his run to the Wimbledon final that year, and Andreescu peaked at No. 4 in 2019 after winning the US Open.
Canadian tennis has seen seven players reach the top 10 in either ATP or WTA history, with official rankings available since 1973 for the ATP and 1975 for the WTA.
Auger-Aliassime still has ground to cover to move higher in the standings. He is 2,865 points behind the current world No. 3, Alexander Zverev, with the rankings showing Zverev at 7,305 points and Auger-Aliassime at 4,440.
The Canadian will shift his focus to grass. He begins his grass-court season this week at the ATP 250 event in ‘s-Hertogenbosch, entering as the No. 1 seed. After a first-round bye he will open against either Hubert Hurkacz or Marton Fucsovics.
The new ranking reflects a season of important progress for Auger-Aliassime and cements his place among the highest-ranked Canadians in modern tennis history.
