After firing fitness coach Umberto Ferrara over a failed doping test, tennis superstar Jannik Sinner reunited with his former trainer ahead of the 2025 Cincinnati Open.
The World No.1 tested positive for Clostebol, a prohibited substance, at last year's Indian Wells tournament. Following a lengthy legal process, Sinner was handed a three-month ban, which saw him miss much of the ATP season between this year's Australian Open and Roland Garros.
Nonetheless, the Italian would return to action at the French Open, where he finished runner-up to Carlos Alcaraz. Subsequently, Sinner would go on to avenge his loss in Paris when he defeated Alcaraz to win his maiden Wimbledon title a few weeks later.
Sinner and Ferrara parted ways just before last year's US Open, as the World No.1 fired his fitness trainer soon after the news of Sinner's positive doping results were made available. Ferrara was reportedly in charge of Sinner’s anti-doping compliance, and was subsequently let go once the news broke. But to the shock of everyone, the two have reunited as Sinner begins his campaign on the North American hard courts.

Ferrara's history with Sinner played a role in the hiring process
"The decision has been made in alignment with Jannik’s management team as part of ongoing preparations for upcoming tournaments, including the Cincinnati Open and US Open,” read a statement from Sinner's team. "Umberto has played an important role in Jannik’s development to date, and his return reflects a renewed focus on continuity and performance at the highest level."
During his press conference at the Cincinnati Open, Sinner made a brief reference to his reunion with Ferrara.
"Yeah, I think we said it all, everything in the statement,” said the four-time Grand Slam champion. “I’m very happy to be here and play again this tournament.”
As the top seed in Cincinnati, Sinner received a bye in the first round. The two-time Australian Open champion will face Colombian qualifier Daniel Elahi Galán in the second round on Saturday.

Growing up in a household where soccer was king, my earliest memories are filled with chants from packed stadiums and the rhythm of a ball being passed across neighborhood streets. But somewhere along the way, the quiet elegance and raw emotion of tennis pulled me in. What began as a curiosity became a lifelong passion; not just for the sport itself, but for the stories it tells: of grit, of heartbreak, of improbable comebacks and human resilience.
As a tennis writer, I bring the observational lens of someone who didn’t grow up in the sport, but fell in love with it as an outsider; a perspective that lets me see both its technical beauty and its emotional depth. Over the years working with TennisUpToDate, I’ve had the privilege of reaching more than 3.5 million readers worldwide, with one of my features ranking among the site’s top three articles.
With a background in storytelling and a creative mind always searching for meaning beyond the scoreboard, I aim to craft narratives that go deeper than results and rankings. Whether it’s a rising star breaking through or a veteran fighting off Father Time, I try to capture the heartbeat behind the headlines.

- 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.

Bad enough the NHL allows Ovachenko (a Putin Supporter and Campaigner) to live and play in the USA. Let's not forget the STATE SPONSORED RUSSIAN DOPING PROGRAMS still in effect today.
mandoist31-10-2026 - Osaka's mental state apparently does not allow her to reach any more Quarter Finals? I mean, she doesn't really have the time for tennis with all the pre-planning that must go into her 12 year-old "fashion" goals.
