But the Chinese world. nr. 1 Shi Yuqi proved to big a challenge for the Dane in the final.
Antonsen won the first edition of the tournament in 2024, but could not match last year's performance in the final.
Shi Yuqi was greeted by a loud cheering roar when he made his entrance on the court, but the Chinese favorite could not live up to the expectations in the opening stages of the match.
Shi Yuqi made too many mistakes, and Antonsen quickly took a 6-1 lead. But Shi Yuqi gradually recovered and won a tight first set 22-20 converting his second set point.
Shi Yuqi raced to a 6-1 lead in the second set and never allowed Antonsen back into the match. All Antonsen's efforts to recover fell short and Shi Yuqi won the second set comfortably to the immense joy of the local crowd.
