Novak Djokovic celebrated his 38th birthday in style on Thursday, securing a hard-fought victory over Matteo Arnaldi at the Geneva Open. The Serbian tennis legend advanced to the semifinals with a 6-4, 6-4 win, showcasing his resilience and skill in a match that kept fans on the edge of their seats.

Djokovic faced a challenging moment in the second set when he trailed 3-1 after breaking his racket in frustration. However, he quickly regained his composure and rallied to win five consecutive games, clinching the match on his first match-point opportunity.

"I'm sorry for the racket, it's not a good example particularly for the young ones," Djokovic said in an on-court interview. "Thank you for your support. I know that with the cold temperatures it's not easy to stay here."

The match was a testament to Djokovic's enduring talent and mental toughness, as he overcame both the chilly weather and a determined opponent. His next challenge will be in the semifinals, where he will face the winner of the late match between Alexei Popyrin and Cameron Norrie.

In other matches, top-seeded Taylor Fritz was upset by sixth-seeded Hubert Hurkacz, and fourth-seeded Karen Khachanov fell to 128th-ranked Austrian qualifier Sebastian Ofner. The day was marked by several upsets, highlighting the unpredictable nature of the tournament.

Djokovic's performance continues to inspire fans and fellow players alike, proving that age is just a number when it comes to competing at the highest level of tennis.
