Jannik Sinner is still waiting for a final decision on his doping case from March 2024. The ITIA cleared him of any wrongdoing before the US Open, but WADA shocked everyone by appealing the decision in October. The case is still ongoing.

Former British player Tim Henman recently spoke to ‘Sky Sports Tennis’ about how this case affects tennis. Sinner’s hearing at the CAS in Lausanne is set for mid-April. If found guilty, he could face a suspension of one to two years.

Sinner’s biggest strength is his hunger to improve. He worked even harder in the off-season and started 2025 in top form. His efforts paid off as he defended his Australian Open title successfully.

After losing to Alexander Zverev in the fourth round of the 2023 US Open, Jannik Sinner finished the season strong. He defeated Novak Djokovic twice, won two singles titles, and helped Italy win the Davis Cup. All of his success came on hard courts. He started 2024 ranked world No. 4 and soon won his first Grand Slam at the Australian Open.

Sinner’s dominance on hard courts grew throughout 2024. He won seven titles, including the US Open, three ATP Masters 1000 events, and the ATP Finals. His incredible season made him the clear world No. 1. His lead was so strong that no matter how he performed in Melbourne in 2025, his ranking was safe.

Defending his Australian Open title, Sinner looked unstoppable. Just like his US Open run, he lost only two sets on his way to the trophy. In the final, he beat Zverev 6-3, 7-6(4), 6-3, getting revenge for his 2023 US Open loss. He never faced a break point, proving how much stronger he had become.

Sinner is now on a 21-match winning streak in hard-court Grand Slams. He is only the fifth player in the Open Era to win three in a row, joining Djokovic, Roger Federer, Ivan Lendl, and John McEnroe. Of them, only Federer won more than three, claiming five straight hard-court majors from 2005 to 2007.
