Brad Gilbert praises Jannik Sinner's ATP Finals title and cheers on Darren Cahill

Former coach of Andre Agassi and Coco Gauff, Brad Gilbert, praised Jannik Sinner's victory over Taylor Fritz to claim his spot in the ATP Finals and congratulated his colleague Darren Cahill. The 23-year-old tennis player defeated the American 6-4, 6-4, securing his 8th title of the season.

Sinner finishes the season with more than 4,000 points ahead of Alexander Zverev (No. 2), an impressive 70-6 record, and 8 titles. After Sinner's remarkable year, Brad Gilbert shared his congratulations, having recently ended his partnership with WTA No. 3 Coco Gauff.

"Tremendous effort from Sin City 🌆 @janniksin 1st player since 1986 @atptour finals to not drop a set. Absolutely dominating since Cincinnati, I tip my cap 🧢 to my buddy @darren_cahill what a year 😎👍👌👊💪" Gilbert wrote on X.

Jannik Sinner delivered a historic performance at the ATP Finals this year, becoming the first player to win the title without dropping a set since Ivan Lendl in 1986. He is also the first Italian to lift the trophy and continues to be hailed as the best Italian tennis player in history.

"It’s amazing, it’s my first title in Italy, and it means so much to me," said Sinner. "It’s something very special. I just tried to understand what works best for each opponent, trying to play my best possible tennis. That was the key."

"It was a very high-level tournament from my side. At times, I couldn't have played better, so I am very happy," he added.

The world No. 1 has ended his ATP season but still has one last challenge to face starting Tuesday at the Davis Cup Finals. Along with Team Italy, they are the defending champions, and Sinner will be their hope to start off on the right foot in the quarterfinals against Argentina. The 2-time Grand Slam champion is set to debut against Sebastian Baez in the second singles match.
