Ronnie O'Sullivan suffered a shocking 10-7 defeat to Thepchaiya Un-Nooh in the World Open final, ending his bid for a record 42nd ranking title. The Thai player delivered a match-winning performance, sinking a 147 break in the penultimate frame to seize control. Despite O'Sullivan's early 4-0 lead, Un-Nooh won six consecutive frames to level the match. The Rocket retaliated with three consecutive century breaks (114, 102, 136), edging ahead 7-6 before Un-Nooh closed out the final four frames, including a maximum break to win 9-7.

O'Sullivan's historic 153 break in the tournament quarter-final—achieved via a free ball after Ryan Day's missed snooker—set the stage for his dominant 5-0 semifinal win over Wu Yize. However, Un-Nooh's resilience proved decisive, marking him as only the second Thai player to claim a full-format ranking title after James Wattana. The result cements Un-Nooh's emergence as a top-tier competitor and adds intrigue to the 2024 snooker season.

O'Sullivan, 50, remains focused on his first World Seniors Championship appearance this year. His World Open run included victories over Ross Muir, Shaun Murphy, and Day, showcasing his enduring skill. Un-Nooh's victory highlights shifting dynamics in professional snooker, as veterans face rising challengers. With the World Seniors Championship approaching, attention now turns to whether O'Sullivan can reclaim form against younger rivals.
