What Happened: Boosarawongse vs Matsuda ITF M15 Bali Final

Thanaphat Boosarawongse entered the final having come through qualifying, making his title run one of the longest paths in the draw. Ryuki Matsuda earned his place in the final by defeating compatriot Ryotaro Taguchi 7-6(8), 6-3 in the other semifinal. The two met at Court A, Nusa Dua, with a total prize fund of $150,000 on the line.

Matsuda struck first, taking the opening set 6-4 to put pressure on the Thai qualifier. Boosarawongse leveled the match by winning the second set 6-3 in a more dominant display. The deciding third set went the distance, with Boosarawongse claiming it 7-5 to seal the title after nearly three hours of competition.

Boosarawongse closed with a performance that underlined his resilience across the full draw. Matsuda pushed hard through all three sets but could not convert his first-set advantage into a title.

How the Market Called It: Closing Probability and Accuracy

Polymarket’s prediction market on this match closed with Boosarawongse priced at 100 percent probability of winning. That figure reflected a dramatic 24-hour swing of plus-37.5 percent, with the sharpest movement — a jump of approximately 34 percent — recorded on July 26, the day of the final itself.

The market correctly favored Boosarawongse as the winner. Traders who tracked the final set movements were well-positioned: the closing probability left no ambiguity about which side the market had swung behind. Total volume in the market reached $151,845, almost all of it traded within the final 24 hours, which signals how late confidence consolidated around the Thai player.

The market’s read, while ultimately correct, had its challenges. Boosarawongse entered the final at 51 percent — effectively a coin flip — making this a narrow call that widened decisively only in the hours before the match resolved. Traders who held through the Matsuda first-set win were tested before Boosarawongse came through in the third.

What Is Next for Thanaphat Boosarawongse

Boosarawongse now carries ITF M15 title momentum into the second half of the 2025-26 season. The Amman Men’s World Tennis Championship continues with a second series at Bali, making it a logical next target for a player who has now proven he can win on the surface from qualifying.

Ryuki Matsuda, despite the final-set loss, showed competitive level against a player who outlasted him across three full sets. Matsuda’s draw of future ITF events will attract attention from traders looking for a bounce-back run.
