Vietnam reach the Asiad 20 women's sepak takraw final: the substitution at 3-6 and the recurring slow start

Milan, early hours of 28 September. On the live feed, Vietnam are 6-3 down to South Korea in the opening game of the women's doubles sepak takraw semi-final. Nguyen Thi Khanh Ly leaves the court. Hong Lien comes on. From that moment, Vietnam reel off 12 consecutive points and close the first game 15-6.

I wrote the number 12 into my notebook and sat with it for a while. A sepak takraw game lasts exactly 15 points. A run of 12 straight points covers four-fifths of that distance. That run functioned as a full restructuring of the match, triggered by a single decision from the bench. In volleyball, the sport I have covered for more than thirty years, a substitution touches one slot in a six-player rotation. Here, only two players are on court. Change one, and you have changed half the team.

The arena was nearly empty in the early minutes, the crowd drifting in late because the match sat in the middle of the day. The empty stands of 2026 taught me that strength is measured not in seats but in the people willing to sit down and listen. I listened to this semi-final by reading every rally, and what I heard did not come from the feet of the two athletes.

Context: a different sport, in the same net-rally family

Let us be clear from the outset: sepak takraw is not a volleyball discipline. It is a distinct sport governed by the International Sepak Takraw Federation (ISTAF), played with a ball woven from rattan or synthetic material, and players may strike it only with the feet, knees, chest and head. There is no first pass, no perfect-pass rate, no three-player block, no libero. The only real common ground between the two sports is a net-rally structure with rally-point scoring. I stress this because that structure, and nothing else, explains what happened in this semi-final.

At Asiad 20, Vietnam's women's doubles pair entered the tournament on uneven ground. In their opening match they lost 1-2 to Laos, a result that made the region's followers stop and look again. Two clean 2-0 wins over Myanmar and Malaysia followed. A team that beats Myanmar and Malaysia without dropping a game, yet loses to Laos in the opener, is telling us something about consistency rather than class. This is the kind of data I always put ahead of praise: it does not deny talent, it simply shows that the talent has not yet been anchored to a repeatable process.

The format is 15 points, best of three. This is the single most important technical detail in the whole piece. A 15-point game compresses variance and punishes slow starts in a way a 25-point game never does. Trailing by three or four points in a 15-point game is roughly equivalent to trailing by seven or eight in a 25-point game. Every calculation about "chances" and "form" has to pass through that 15-point funnel first.

The semi-final against South Korea was played at midday on the same day as the deciding group fixture. The opponent is a non-traditional sepak takraw nation: South Korea belongs to a group of East Asian countries now investing in the sport, a very different picture from the familiar Southeast Asian power map, where Thailand is the biggest axis and Malaysia is strong in the men's events.

The second game repeated the script: Vietnam let the Koreans lead 5-1 before clawing back and winning 15-13 at the decisive moment, with Hong Lien shining exactly when it mattered. The final score was 2-0. Beyond the place in the final, the team also delivered the delegation's first medal after 26 and 27 September had passed without one.

Analysis: the real power sat on the bench

The most instructive element of this match is not a decisive kick. It is the timing of a substitution.

With Vietnam 3-6 down, head coach Nguyen Thi Vui pulled Khanh Ly and sent on Hong Lien. The decision came early — before the game had drifted beyond reach — and that is the signature of someone reading momentum rather than reacting to the scoreboard. Many coaches wait until the deficit deepens before touching a losing line-up. Vui moved at 3-6, at a point when a 15-point game still has room to be repaired.

The specific mechanics deserve emphasis. In sepak takraw doubles, only two players are on court. A substitution does not swap one slot inside a system; it redistributes responsibility across the whole court, changes the serving rhythm, changes the receiving setup, changes the very language of coordination between two people. With two players on court, every substitution is a total change of roles rather than a change of personnel. The radius of impact is therefore far larger than in volleyball, where six players share the load and a substitute may touch the ball only a handful of times per game.

Based on my experience of watching matches, these rhythm flips only work when the incoming player is prepared for one precise task. Hong Lien was not described as a mere backup attacker. The account of the match shows her entering with a brief to finish rallies accurately, and she held that brief to the final point of the second game. The coaching staff appear to keep a deliberate change-of-rhythm option on the bench, and that option is real, rehearsed and used at the right moment. That is worth noting in a sport where squad depth is usually thin.

Alongside that bright spot sits a troubling repetition. Vietnam started slowly in both games. Game one: 4-1 down, then 6-3 down. Game two: 5-1 down. When a pattern appears twice in two games of the same match, it is no longer an accident. It is a structural trait: the team surrenders control of the rhythm early and only recovers it after a quarter of the match has already passed. In a 15-point format, repeatedly betting on comebacks is a high-variance wager, and high variance always collects its debt eventually.

Another data point belongs beside this picture: in the men's regu event, Vietnam stopped at the semi-final and took bronze. In women's doubles, the country has a pair that has stood on top of the world championship. Vietnam's sepak takraw strength is concentrated in a single elite unit rather than spread across a system. That is what gets them to a final, and it is also what makes the future of the event depend on a very narrow variable. From the Milan pitches to the media door: we do not merely play, we open roads — and those who open roads must look at the road behind them, not only at the finish line ahead.

On the other side of the net, South Korea reached the semi-final. An East Asian nation outside the sport's traditional heartland making the last four is a signal that Southeast Asia's protective moat is narrowing. For a sport whose development base leans heavily on school systems and national training centres, the arrival of a country from outside the traditional geography is always a signal to be read seriously.

A counter-intuitive angle: Vietnam's real opponent is not the Philippines

Before the final, domestic opinion circulated the view of experts that Vietnam's chance of gold was "very bright", based on an overwhelming head-to-head record against the Philippines.

I want to read that number differently.

Historical head-to-head data describes the past, not current form. A team can beat an opponent ten times in a row and still lose the eleventh, if the eleventh is the one time the opponent changes its line-up. We have no technical metrics at all for the Philippines at this tournament: no finishing success rate, no error count, no ball-contact data. Without that data, any claim of "overwhelming" superiority is a belief dressed up in historical numbers.

Vietnam's real opponent in the final sits on their own side of the net. It is the habit of starting slowly. It is the 15-point format, where a three-point run by the other side carries the weight of a five-point run in a longer format. And it is the schedule: two matches in a single day across the group stage and the semi-final, then a final at 7:40 a.m. on 29 September. The 7:40 a.m. slot is a rarely modelled variable, and for a team whose game is built on emotional momentum, bringing the body to match rhythm at that hour is anything but simple. It is the sort of detail a high-performance unit would rehearse in advance; its absence from the pre-match previews points to a gap in sports-science support around the team.

There is a deeper layer I want to state plainly. Throughout my career writing about women's sport, I always check whether a sport has a data system, because a data system reflects how seriously the industry takes it. Women's sepak takraw in this region has almost no publicly available technical data. A sport that cannot measure itself will struggle to be funded at the right level, and this is a loop that female athletes absorb first. Transfers are not just numbers; they are a map of power and opportunity — and women deserve a place on that map. In sepak takraw, that map has not even been drawn.

Takeaway

Vietnam's women's doubles pair walk into the final as the number-one contender, and that status has a genuine basis: a pair that has won a world title, a coach willing to make a call at 3-6, and a bench option that proved itself in the hardest match of the tournament.

But if I could send the team one sentence, it would not be about the Philippines. I would ask: if the opening game of the final begins at 1-4 again, will we be calm enough to understand that this is the moment the match truly starts, not the moment it is about to end?

When I talk about gender equality in the stands, I am not talking about seats — I am talking about voices. And the voice of a women's sport only carries when we take the trouble to measure it as seriously as we measure any other.
