Earlier this year, Carlos Alcaraz's peers nicknamed him "Fed05" as a nod to Roger Federer's immaculate 2005 season, which saw the Swiss go 81-4 to maintain the second-greatest winning percentage (95.3%) in a season.

Jannik Sinner joined some pretty special company on Sunday as he became just the second men's tennis player in the Open Era behind Roger Federer to not lose in straight sets during the entire season. Federer accomplished this difficult feat back in 2005. Serena Williams also achieved this in 2013.

The Davis Cup had been a defining moment for Sinner in 2023. He saved three match points against Novak Djokovic in the Italy vs Serbia semi-final last year and went on to beat Djokovic in both the singles and doubles before Italy downed Australia in the final.

The 23-year-old could be banned from tennis for up to two years if the Court of Arbitration for Sport (CAS) upholds the World Anti-Doping Agency (WADA) appeal into Sinner’s doping case. He tested positive for clostebol, a banned anabolic steroid on March 10 at the BNP Paribas Open held in Indian Wells, Calif, and on March 18, out of competition.

Jannik Sinner defeated Taylor Fritz in the title contest at the 2024 ATP Finals and consequently recorded his 17th top-10 win of the year.

Jannik Sinner closed his incredible 2024 season with the Davis Cup win. However, he achieved a feat that only Roger Federer and Serena Williams had achieved this century. Jannik Sinner joined an elite club on Sunday,
