Jannik Sinner Reinstates Umberto Ferrara Amid Lingering Doping Case Fallout
Jannik Sinner rehired trainer Umberto Ferrara after doping case; Naldi remains sidelined.
Jannik Sinner has rehired fitness trainer Umberto Ferrara, nearly a year after the two were involved in a doping case that rocked the tennis world. Ferrara, previously dismissed alongside physio Giacomo Naldi following positive tests for the banned substance clostebol, returns to Sinner’s team despite the controversy.
In March 2024, Sinner tested positive twice for clostebol but was later cleared of any fault or negligence by the International Tennis Integrity Agency (ITIA). The investigation attributed responsibility to Ferrara and Naldi, uncovering that Ferrara had supplied Naldi with trofodermin, a spray containing clostebol, to treat a cut on Naldi’s hand. Despite warning Naldi of the substance’s prohibited status, Ferrara reportedly knew Naldi typically treated Sinner without gloves. The contamination allegedly occurred when Naldi massaged Sinner after applying the spray to his finger.
Following the ITIA’s report, Sinner dismissed both Ferrara and Naldi, stating he could not continue working with them after their mistakes. Sinner served a three-month ban due to the violation but ultimately succeeded in settling with the World Anti-Doping Agency, which had sought to appeal the ITIA’s decision.
Despite Ferrara’s return, Naldi remains absent from Sinner’s entourage. Speaking to Repubblica, Naldi expressed emotional distress over the saga: “Here we go again. Now the nightmare begins again, like last summer. I have no intention of commenting. It’s a story that has made me too sad; it has damaged my image. When the time is right, we’ll talk about everything calmly. I don’t want to ruin this holiday, too. Right now, I just want to be left alone. I prefer not to comment. Maybe one day I will, but right now it hurts too much.”
Sinner has not publicly addressed Ferrara’s reinstatement. The world No. 1, who guided him to the top ATP ranking and his first Grand Slam at the 2024 Australian Open, is set to return to competition at the Cincinnati Open, his title defense after missing the Canadian Open. This will precede his quest to defend the US Open crown.

From Fans to Contenders: Iva Jovic and Learner Tien’s Indian Wells Homecoming
Iva Jovic and Learner Tien grew up visiting Indian Wells and return this year as rising tour stars .
As children both Iva Jovic and Learner Tien visited Indian Wells with their families, the Tiens driving from Irvine and the Jovics from Torrance. Each arrived as a fan: Jovic waited in the sun for two and a half hours to try to get Novak Djokovic’s autograph; Tien’s earliest priority was the tournament’s frozen lemonades. “Those things are one of the greatest things ever,” he said, and he also remembers snagging a signature as Djokovic walked out of Centre Court. “I was one of the people hanging over the wall.”
Their journeys to the professional ranks have been rapid. Jovic only committed to tennis full time after the pandemic closed other sports in 2020. A year later she won the Orange Bowl and, four years after that, reached the Top 50. After an extensive pre-season working with coach Tom Gutteridge, she described the process plainly: “I took a pretty long pre-season, so I had a lot of time to get everything done.” She added, “There was a couple of specific things I was working on. There was a lot of physical stuff in the gym, a couple of technical tweaks with my ground strokes, with my serve, which took time as well.” The work showed in 2026: a final in Hobart, a first major quarterfinal in Melbourne and a 13-4 start to the season that left her ranked No. 18.
Tien’s progression has been similarly steady. After joining the tour in 2025 he displayed consistency and smart point construction, rising into the Top 30 as a rookie. By February 2026 he was at a career-high No. 23. He enlisted Michael Chang for coaching last summer to refine his serve, toss and tactics and has seen results, including a quarterfinal in Australia and a semifinal in Delray Beach. On Chang he said, “In general I think he’s very encouraging. He’s never getting down whether I’m playing well or whether I’m playing poorly. He’s always just consistently just giving me good energy, a lot of support.” He later joked, “There’s not that much video from way back then.”
Both players are second-generation Californians with immigrant family stories and compact frames — Tien 5’11, Jovic 5’7 — yet both have carved pathways that rely on craft, fitness and variety rather than sheer power. Tien will also appear in the doubles draw with Daniil Medvedev. For both, Indian Wells is a homecoming and a moment to return to the other side of the autograph line.

Cobolli Downs Tiafoe to Claim Acapulco Title, Poised for Career-High No. 15
Cobolli beats Tiafoe 7-6(4), 6-4 to win Acapulco; third ATP title and a projected rise to No. 15 now
Flavio Cobolli completed a remarkable week in Acapulco with a 7-6 (4), 6-4 victory over Frances Tiafoe to lift the ATP 500 trophy. The straight-sets scoreline belies a hard-fought encounter that lasted two hours and nine minutes, with the opening set alone running 70 minutes.
The win is Cobolli’s third ATP title and matches the biggest level of his previous triumphs. His first two tour-level trophies came last year, both on clay: Bucharest, an ATP 250, and Hamburg, an ATP 500. With the rankings update on Monday, he is projected to move from No. 20 to a new career-high of No. 15, surpassing his prior peak of No. 17.
Both finalists had dramatic semifinal nights. Cobolli rallied from 3-1 down in the deciding set to beat Miomir Kecmanovic, 7-6 (5), 3-6, 6-4. Tiafoe survived an all-American duel with Brandon Nakashima, 3-6, 7-6 (6), 6-4, after Nakashima served for the match at 6-5 in the second set and then came within two points of victory at 6-all in the tiebreak.
In the final Tiafoe threatened early, holding a 3-1 advantage in the first-set tiebreak before Cobolli edged the set. Tiafoe rallied again in the second, breaking back to level at 4-all, but Cobolli closed the match by winning eight of the final 10 points, breaking for 5-4 and sealing the title with an ace, his 10th of the match.
The result also carries historical notes. At 23, Cobolli is the youngest champion in Acapulco since a 22-year-old Dominic Thiem won in 2016. He is the first Italian to capture an ATP title this year and, as the nation’s No. 3, will join countrymen Jannik Sinner and Lorenzo Musetti, currently ranked No. 2 and No. 5, in the Top 15.

Bouchard: Indian Wells an ideal stage for Ben Shelton to carry U.S. hopes
Bouchard backs Ben Shelton as top U.S. hope at Indian Wells amid Paul and Fritz challenges this week
The 2026 BNP Paribas Open arrives with main-draw action beginning Wednesday, March 4, and American men figure prominently in the conversation at Tennis Paradise. Eugenie Bouchard singles out a compact group of U.S. contenders and places Ben Shelton at the center of expectations.
Ben Shelton. His game has shown clear evolution and he often lifts his level at the biggest events. With Indian Wells regarded as the premier U.S. tournament after the US Open, the setting feels appropriate for Shelton, who already won a first Masters 1000 title in Canada last summer.
Tommy Paul. After a 2025 season hampered by injury, Paul appears to have recovered and has produced a strong start to 2026. His Delray Beach win over Taylor Fritz—the only American man to win Indian Wells since Andre Agassi in 2001—was certainly a statement about his readiness to return to the Top 10 and beyond. Back to full health in Australia, he played great to reach the second week and gave Carlos Alcaraz all he could handle over three close sets in the fourth round. If he stays healthy and consistent, Paul could be the most dangerous American in the draw.
Taylor Fritz. Local support and familiarity with the event add weight to his prospects. “Total transparency: how can i go against my man in his hometown tournament? A tournament he’s the only one of his countrymen to have won before, no less.” That hometown element and previous success at the event create a compelling backdrop for his campaign.
Indian Wells will demand serve, return and stamina across large courts and long days. Between Shelton’s upward trajectory, Paul’s return to form and Fritz’s home-court narrative, the U.S. contingent arrives with several credible candidates to produce the best American result as the Sunshine Swing begins.
