Jannik Sinner seemingly addressed his doping ban in his year-end message to fans as the world No. 2 admitted that "some lows were difficult to accept" in 2025. 

The Italian tennis star kicked off his 2025 season by successfully defending his Australian Open title.

A couple of days later, it was announced that Sinner settled on a three-month doping ban with the WADA and that he would be suspended between February 09 and May 04. The settlement came just before the former world No. 1 was due to appear in front of a CAS judge.

After returning to tennis in May, Sinner won his first Wimbledon title and captured back-to-back ATP Finals titles. Also, the Italian finished as runner-up to Carlos Alcaraz in the French Open and US Open finals, as well as lost the Year-End No. 1 battle.

Overall, it was still a strong season for Sinner, considering that he won two Grand Slams and improved to four Majors overall.

“Guys, what a year it has been. Some highs that felt incredible, and some lows that were very difficult to accept. But throughout this whole year, I don’t see only results. I see big lessons," the 24-year-old said in a video message uploaded to his Instagram.

“I’m really thankful for my whole team, my family, and all of you guys, for all the support you gave me throughout the whole year, it really means the world to me. For now, I wish everyone a Happy New Year, celebrate it with the people you love, and see you all very soon again on the court. Ciao Ciao.”

Just as he did in the previous two years, Sinner opted not to play any tournaments in the first two weeks of the season. Instead, he will start his season at the Australian Open.
