For long-time tennis fans, Damian Kust’s voice wasn’t just familiar; it was essential. He did more than report on-court action; he helped fans understand the true essence of the sport. But today, tennis has lost a true admirer to a painful illness he had been battling for a long time. Kust was just 26.

A respected journalist and podcaster, Damian Kust was known across the tennis circuit for his warmth and expertise. He earned admiration from coaches and players for his tireless dedication to the ATP Challenger Tour, the often-overlooked circuit that shapes the next generation of stars. His deep knowledge and genuine curiosity for the game shone in every match he covered. Through his words, players fighting to break through finally found visibility and recognition.

Kust had hoped to do more for the sport he loved. Through his podcast, he wanted to shine a light on rising stars and tell stories that often went unnoticed. But for the 26-year-old, fate had other plans. Last year, he was diagnosed with a rare autoimmune disease, and his health began to decline. Since October 2025, he had been hospitalized and underwent three major medical procedures, including two liver transplants. Even during recovery, he stayed connected with fans, sharing occasional updates on social media.

However, on January 6, Kust’s parents took to his official X profile (@damiankust) to share the news of his tragic demise in a tweet:

“We are the parents of Damian. Today our best son passed away. Thank you all for your support.”

Kust’s energy stretched far beyond written words. His enthusiasm came alive through podcasts, articles, and social media, where he championed emerging players and celebrated matches that few noticed. You could often spot him courtside, absorbing the atmosphere, notebook or phone in hand. His X header showed a still from Tennis TV capturing him in the stands; a perfect reflection of his love for the sport.

Players, coaches, and fans loved his authenticity and poured out heartfelt tributes, remembering the man who made the Challenger Tour feel like home.

Tennis world mourns the demise of Damian Kust

Under the tweet written by Kust’s parents, American ex-pro John Isner shared his condolences, “I am so so sorry for your loss. Damian was so well respected within our tennis community. A truly great guy. May he Rest In Peace and fly high in Heaven with our Lord and Savior.”

The former pro was represented by the 26-year-old journalist several times over the years. Kust often included him in his tweets and reports on tennis records and stats. As a fellow podcaster, and co-host of Nothing Major Podcast, Isner felt the loss deeply.

Renowned coach, commentator and Sky Sports analyst Mark Petchey also penned a heartfelt eulogy for the 26-year-old. He wrote, “Beyond heartbreaking to hear this news. Damian did more for the ATP Challenger Tour and players outside the limelight than anyone has, without seeking any of his own. He loved the sport unconditionally and his posts were a daily reminder what an incredible sport this is when loved for just what it is. My condolences, his light will be missed 💔”
