Mixed Doubles Open in Ho Chi Minh City: Liu Shasha and Hsieh Chia-Chen Upset Yapp – Lu Pair in a Three-Set Final

Aloysius Yapp's missed nine-ball in the deciding rack is a moment I will remember for a long time. Not because it was beautiful. Because it was far too ordinary for the player currently ranked number one on the World Nineball Tour. The Phu Tho arena was packed, applause rose as Liu Shasha and Hsieh Chia-Chen touched hands. The China–Chinese Taipei pair had just completed one of the most notable comebacks in 9-ball pool this season, at the Mixed Doubles Open within the Predator Pro Billiard Series. Looking back at the whole run, I remind myself of an old line: data never lies, but I have misheard it before. The event took place at the Phu Tho Indoor Stadium, Ho Chi Minh City. It is the first of three Predator Pro Billiard Series events in Vietnam, part of a festival that also includes the Saigon Open and the Men's World 10-ball Championship. The format is mixed doubles, with a three-set final, each set won by taking four racks. This structure differs fundamentally from traditional singles events: fast pace, short races, and a one-loss side that allows teams beaten in the opening round to still reach the final. In the losers' qualification round, organisers even used a shootout to settle matches — a tiebreaker that injects high randomness. The Liu Shasha–Hsieh Chia-Chen pair did not enter as top seeds. They lost their opening match, had to travel through the one-loss side, survived a shootout, then won two comeback matches in the quarterfinals and semifinals. Three of their remaining matches went to a deciding set. This is a title run built on resilience and nerve, not dominance. Liu Shasha, a three-time women's nine-ball world champion, is the professional anchor of the partnership. Hsieh Chia-Chen, 33, is the less-discussed piece, but by no means invisible in her rhythm-control role. Their final opponents were Aloysius Yapp — the Singaporean currently ranked WNT No. 1 — and Silviana Lu, a player billed as a breakthrough figure on the women's circuit. The media called them the power couple. That is the promoter's packaging, and it has commercial logic. But viewed professionally, the gap between the two players in the Yapp–Lu pairing is wider than in the Liu–Hsieh pairing, because Yapp sits at the top of the men's game while Lu is still in her establishing phase. The second set saw Yapp and Lu dominate 4-1, showing they could fully control the match when Yapp was at the table. But in the third set, the picture flipped. Yapp's missed nine-ball in a pivotal rack, then a hard five-ball miss, then a scratch on a jump shot — three individual errors at decisive moments. For a world No. 1, that is a notable error cluster. But I will not rush to a conclusion. One match is not enough to define a player's form across a season. The most striking feature of the match was how specialist skills decided the outcome. Nine-ball is not just about potting balls. Jump shots, safety play and defensive battles are where racks are won. Liu Shasha successfully executed a two-five jump combo, and a two-ball jump in the third rack of the final set. Yapp also produced excellent safeties, yet he lost the very safety battle that decided rack three of the last set. The China–Chinese Taipei pair's victory did not come from potting more accurately, but from controlling the table better in difficult situations. Another detail worth noting: in the final set, the Liu–Hsieh pair chose a dry break — a break that pots no ball but controls the cue-ball position and the table layout. For teams without a strong break advantage, this is a rational tactical choice: instead of trying to overpower the opponent, they proactively controlled the situation. Finally, in the deciding rack, Liu Shasha executed shots on the four-ball and the nine-ball described as phenomenal — the two balls that decided the championship. The winner's prize was 38,000 USD for the winning pair. That figure, set beside major professional pool events, shows this is a mid-tier event financially. It also shows that the Predator Pro Billiard Series revenue model relies more on equipment sponsors and ticketing than on broadcast rights. A packed Phu Tho arena is a positive signal for regional market demand, but it does not mean professional pool has become a mass sport in Vietnam. This is where I want to pause on a counter-intuitive angle. The story the media tells is that the power couple fell to the nerve of two players who came through the one-loss side. It sounds compelling. But if we look at the tournament's structure, we must accept one thing: a short-set format, capped at four racks, plus a shootout, is a design that flattens the skill gap. In this format, a world No. 1 can still lose to a lower-rated pair simply because of one miss at an unlucky moment. The final result does not say Yapp has declined, nor does it say Liu–Hsieh are superior in class. It only says that in short-set doubles pool, randomness plays a larger role than we like to admit. Similarly, the Yapp–Lu power-couple story is a marketing product. Professionally, Yapp is the top-ranked player on the WNT, while Lu is a rising talent. The combination generates media appeal, but the gap between the two members is wider than in the Liu Shasha–Hsieh Chia-Chen pairing — where both are in the mature phase of their careers and can cover for each other tactically. From this angle, the China–Chinese Taipei pair's victory is a well-founded result, not a pure shock. There is one data point I want to cite to illustrate the broader context: the Ho Chi Minh City cluster includes three Predator Pro Billiard Series events, plus the Saigon Open and the Men's World 10-ball Championship. This is a deliberate strategy to anchor professional pool in the Southeast Asian market, where audience demand is rising. A Chinese player and a Chinese Taipei player winning a tournament held in Vietnam, ahead of a Singaporean world No. 1 and a rising women's player, is a symbol of professional pool's centre of gravity shifting toward Asia. But I do not want to paint too rosy a picture. The data I have is incomplete. There is no run-out percentage, no pot percentage, no detailed statistics on break quality. Only one financial figure: 38,000 USD for the winning pair. The sample is too small to conclude anything about the development trend of mixed doubles pool. And the final itself, however tense, is a single match — it cannot represent the long-term form of any player. The next thing worth watching, for me, is not this victory. It is Liu Shasha's run at the upcoming Saigon Open. If she goes deep or wins, that will be data reinforcing the hypothesis that she is at peak form. If not, we can treat the Mixed Doubles Open title as a moment of brilliance inside a random format, rather than proof of class. The crowd laughed when they saw the world No. 1 fall. The numbers did not laugh. They only recorded: three sets, twelve racks, a few errors, and one carefully calculated dry break. When home soil is no longer a fortress, I learn to listen to the empty stands. But the Phu Tho stands that night were not empty. They were full, and the applause went to both pairs. Vietnamese pool has just had a memorable night. The question that remains is whether that night is the start of a trend, or merely a flash within a format where randomness is part of the rules.
