Vietnamese Youth Tennis and the Stratigraphy Problem: Why Has a Decade Produced Only One Ly Hoang Nam?

In June 2026, I sat in the fourth row of Court 4 at the Phu Tho tennis complex, my notebook open to page 187. In front of me, a sixteen-year-old player from Binh Duong had just lost after three tie-break sets: 6-7(5), 7-6(3), 6-7(4), against an opponent of the same age from Thailand. The match lasted two hours and fifty minutes. He served four kilometres per hour slower on the first serve than his opponent, but he won 71 percent of his second-serve points. He came to the net 23 times and won 17. He lost. I wrote one more line at the bottom of the page: 'lost but not read'.

People call afternoons like that a failure. I call it a layer of ground nobody has dug into.

In Vietnam, tennis carries a difficult paradox. It is a sport many people can play, from public parks to commercial courts, yet it is a sport whose elite development pipeline is extraordinarily narrow. You can count on the fingers of one hand the Vietnamese players who have entered the ATP top 500 in men's singles over the past two decades. And for nearly ten years, almost the entire elite story has collapsed into one name: Ly Hoang Nam.

This article is about the layer of ground beneath that name. About how the training centres actually operate, about whether the junior tournament structure feeds itself or wears itself down, and about the gap between the number of commercial courts and the number of players who have a real pathway. And about a question nobody wants to answer out loud in domestic tennis meetings: if the system does not change, will the next ten years give us one more name, or only ten more seasons to remember.

I work as a youth academy observer. I do not write reports. I excavate the memories of players nobody has ever told stories about.

Context: a sport running on two separate levels

To talk about Vietnamese youth tennis, you first have to separate its two operating levels, because these two levels barely speak the same language.

The first level is the grassroots level. This is the level that is swelling and hottest. Hundreds of private tennis complexes in Hanoi, Ho Chi Minh City, Da Nang, Binh Duong and Can Tho have sprung up alongside new urban areas. Amateur tournaments, corporate tournaments and club cup events run all year round. The number of regular players is rising, and the number of recreational players is rising even faster than the number of courts can keep up with in some inner-city districts. In terms of feeling, this is a very alive sport.

The second level is the elite level. This level is narrow, cold, and almost entirely dependent on a handful of centres backed by state resources or corporate money. The national sports training centre, a few provincial sports authority centres, a few corporate-sponsored academies, and clubs with training contracts for families that can afford them. The number of athletes supported under a professional training regime here is so small that every time one training slot closes, a whole group of children has to change direction.

The gap between these two levels is the tragedy of Vietnamese youth tennis. The grassroots level is big enough to produce a generation of twelve-year-olds full of potential. But the elite level is too narrow to keep them when they turn fifteen, seventeen, nineteen. That is why a large number of talented young Vietnamese players disappear from the map not because they lost on court, but because the system had no place to put them.

I have spent years sitting at both levels. What I have drawn from it can be summed up in one sentence: Vietnam is good at producing, and poor at nurturing.

The base layer: the structure that produces players

I start from the lowest layer, where young players are actually born.

Vietnam currently has several main types of training environment. The first is school talent classes and summer classes. Their strength is broad reach, low initial cost, and helping children get used to the basic coordination skills: moving, tracking the ball, and making contact with the racket. But their limitation is that their goal is education, not performance. You cannot build a top-500 player from a class with one shared lesson plan for thirty children.

The second is private centres and clubs. This is the most realistic environment for most families whose children follow this path. Quality varies enormously between centres and within a single centre. At some clubs in Binh Duong, Ho Chi Minh City and Hanoi, I have seen coaches build age-based lesson plans, keep session-by-session data, and conduct periodic assessments. At other centres, the lesson plan is still 'hit the ball steadily, hit the ball a lot, hit until it feels natural'. The difference is not in the number of hours, but in whether there is a system for recording progress.

The third is elite training centres with state or corporate capital. This is where it is possible to send a young player to international competition. But the number of slots is limited, and selection conditions often come later than the moment when a player truly needs investment.

What I want to say is not which type is better. What I want to say is that these three types of environment barely talk to each other. A child moving from a talent class to a private club often loses three to six months readjusting. A player returning from an elite centre to a club is often treated as 'finished'. There is no shared database connecting the levels. There is no single file that follows a player from age ten to age eighteen.

In football, I once wrote that every academy is an excavation site. In tennis, that is even truer, because tennis is an individual sport, and every player has a path that cannot be copied. But precisely because it is individual, the record-keeping must be even more careful. In Vietnam, most decisions about a young player — promotion, relegation, changing coach, going on a training camp — are still based on eye observation, the feeling of whoever holds authority, and short-term performance pressure. Data, when it exists, is scattered in the notebooks of a few coaches and nobody collects it.

The Covid period, for an observer like me, turned out to be an open door. When tournaments stopped, I had time to rewatch hundreds of recorded junior matches that had been played before and to record every metric by hand. When Covid closed the courts, I opened the data vault. Youth tennis never stops beating.

Core analysis: the gap between hours on court and a competitive pathway

This is the part I want to give the most space to, because this is where the numbers can truly say what the naked eye cannot see.

Training volume and session quality

One of the most common misconceptions among parents with children following tennis is: the more training the better. I have watched young players aged thirteen and fourteen train three sessions a day, six days a week, for months on end. On paper, that volume looks impressive. In reality, it usually carries three consequences that few assess correctly.

The first is a decline in technical quality in the later parts of a session. When tired, a young player tends to choose the option that demands the least: hitting safely, reducing amplitude, reducing spin speed. Training in that state does not build technique. It builds a habit of coping.

The second is accumulated injury. Tennis is a sport with high repetitive load, strong rotational impact on the shoulder, elbow, lower back and ankle. At an age when the body is still growing, training excessive volume while the physical foundation is not yet sufficient is a recipe for chronic injuries that only surface three to five years later. I have tracked young players who at fifteen had every skill they needed, and by nineteen no longer had the fitness to hold the pace in a three-set match against a foreign opponent.

The third, and least discussed, is the erosion of motivation. Tennis is a sport where, after a difficult period, the feeling of progress only returns later. But there is also a threshold beyond which the price of returning has become greater than the value of returning. I have known promising young players who, after years of training like that, simply stopped one day and never came back. Not because they lacked talent. Because they had paid too high a price for a pathway that was not designed for their bodies.

The lesson I draw from observational data: hours have a weak correlation with the speed of progress. What correlates strongly is the number of sessions with a clear objective, feedback afterward, and a written record.

A young player training four times a week, where every session has a specific technical goal, will progress faster than a player training ten times where nobody evaluates the session afterward. This is something developed tennis nations have understood for a long time, but in Vietnam it is still treated as a secondary condition.

Physicality and the height problem

At the elite level, men's tennis today is a sport where height and strength have a direct impact on results, especially on the serve and on the ability to finish points. Some Vietnamese players have good technique and good game intelligence but are below average in height when placed beside East Asian opponents of the same age. This is an objective limitation that cannot be compensated for by willpower.

But an objective limitation is not a sentence. How a small tennis nation responds to that limitation is what separates good systems from average ones.

In one direction, you accept a counter-attacking style based on high movement speed and the ability to sustain long rallies. This direction demands an exceptional physical foundation and the skill to hit balls from unbalanced positions, plus an extremely resilient mentality.

In the other direction, you push the serve and an early net approach to shorten each point. This direction demands a serve technique perfected at a very early age, along with deep coaching in the volley and the overhead.

In Vietnam, most centres still lean toward the first direction, without corresponding investment in fitness. The result is that many young players play a defensive game but are not fit enough to run that game all the way, and also lack a proactive weapon to change the direction of a match when they are being pushed back.

I have recorded a small sample from national junior matches: players who win long three-set matches are usually not the players with the best shots, but the players with the highest stability index in the last two sets. That stability comes from a physical foundation and from the ability to maintain stroke structure when tired. Both require long-term investment and cannot be added by a short training camp.

The serve: the shot invested in last

If there is one shot where Vietnamese youth tennis has lost the most value, I would say it is the serve.

In a modern men's singles match, the serve is the stroke with the largest share of total points. A good server can hold games with less risk, and therefore has more energy for return games. Conversely, an average server must accept more variables in every service game, and over the long run that creates accumulated psychological pressure.

Many young Vietnamese players learn serve technique relatively late, often after the body has already formed many other movement habits. Those habits are very hard to break. A serve motion learned incorrectly at fourteen is very hard to fix at eighteen if the player has continued to compete with that motion for four years.

One thing worth noting: many young players have a fairly high first-serve percentage but low speed and spin. That is a 'safe' serve that creates no advantage. It allows the player to keep the ball in play, but it also opens an immediate attacking opportunity for the opponent on the return. Over the long run, as international junior competition develops, this type of serve quickly becomes an exploitable weakness.

I believe one of the highest-return investments for Vietnamese youth tennis over the next ten years is to separate serve coaching into a programme with a dedicated specialist, recording speed and spin data at each stage of a player's development. This is nothing new in the world, but it is still quite foreign to many domestic centres.

The junior tournament structure: where players are fed or starved

A young player improves through three factors combined: quality training, sufficient match frequency, and suitable opponents. In Vietnam, the second and third factors are usually weaker than the first.

The number of domestic junior tournaments has increased, but distribution is very uneven. Most tournaments are concentrated in a few major centres. For a young player from a distant province, travel and accommodation costs for one tournament can equal several months of training costs. This creates a very clear effect: players from better-off families get more match exposure, and therefore tend to progress faster, creating a self-reinforcing gap.

Match frequency also needs consideration. Too few matches leaves a player short of experience in handling situations. Too many matches without interleaved training periods burns the time needed to build technique. This is one of the most fundamental contradictions in youth development.

Beyond that is opponent quality. A young Vietnamese player who competes only domestically for years will get used to one type of opponent. When stepping onto the regional stage, the player must adapt to a different pace and style. This adaptation window is a phase where it is very easy to lose points and lose confidence.

I have watched many international junior matches where a Vietnamese player played very well in the first set, then faded in the second and third. This is often interpreted as a psychological issue. I do not think it is purely psychological. It is the consequence of lacking the habit of competing at high intensity over a long period.

Psychology and environment: the submerged part of the iceberg

In an individual sport, the psychological factor hovers over every point. A player has no teammate to share the pressure with. No coach is allowed on court for most of the match. Between serves, the player has only himself and a few seconds of silence.

In Vietnam, building psychological capacity for young players is still at a low level. A few centres have begun hiring sports psychologists, but the numbers are small and the intervention periods are short. Most young Vietnamese players learn to cope with pressure through competition, and that is a very expensive way, because every stumble can burn away part of their confidence.

The environment also plays an important role. A young player needs to be in a group with opponents of a similar level, so they can compete, learn from each other, and keep motivation. This training group in Vietnam is usually very small. When one player in the group pulls ahead, the whole group loses part of its motivation. When one player leaves for family reasons, the whole group is affected psychologically.

I believe the problem is not that Vietnamese players lack courage. The problem is that they have to build courage themselves in an environment short of support tools. That is a systemic unfairness.

Cost: the equation families must solve alone

Raising a young player along the professional path in Vietnam is one of the most expensive family investments in sport. The cost is not contained in tuition fees. It includes: court rental, private coaching, fitness coaching, physiotherapy, equipment and regular restringing, travel, food and accommodation at tournaments, sports medical insurance, and the time parents must give up to take their children to training.

In many countries, a significant part of this is shared by federations, clubs or sponsorship funds. In Vietnam, most of it still sits on the family's shoulders, especially between the ages of eleven and fifteen, a period with no results to persuade sponsors.

The long-term consequence is a faulty selection. The players who go far are not necessarily the best players, but the players whose circumstances allow them to sustain the pathway longest. This is the hardest kind of wasted talent to fix, because it does not produce visible failure. It only produces quiet disappearance.

Regional comparison: why Thailand and Japan are ahead

Set beside Thailand and Japan, the gap in Vietnamese youth tennis becomes clearer in two respects.

The first is the tournament system. Thailand has a steady annual chain of ITF and Challenger events, meaning young players do not need to travel far to face international opponents. Japan has a school system connected to clubs, allowing young players to study and compete in parallel without having to choose one.

The second is the transition pathway. A young Japanese player moving from high school to university does not suffer a break, because the university system there still allows professional competition. A young Thai player has academies linked to foreign partners for long-term training camps. In Vietnam, similar pathways exist but in very small numbers, and are usually not communicated to most families.

Vietnam's strength lies in its broad grassroots base and the pace of facility development. If the elite level learns to use the grassroots level as a supply source instead of treating it as another world, this gap can narrow much faster than many people think.

The counter-intuitive angle: things that are right but sound wrong

Here I want to speak directly to three widespread beliefs that I think are holding back Vietnamese youth tennis.

The first belief: the best players must be sent abroad as early as possible. This is not entirely wrong, but it is only true on the condition that the player already has a technical foundation, physical foundation and minimum language skills. Sending a fourteen-year-old abroad without a foundation only creates an unrecoverable shock. That player will train in an environment they do not understand, compete against opponents who are too strong, and lose confidence at exactly the most important stage. Going abroad should be a continuation of a pathway, not a shield for an unfinished one.

The second belief: the more tournaments, the better. The number of tournaments is not the most important indicator. The more important indicator is the distribution of tournaments by age, by level, and by geography. Ten tournaments concentrated in one city are not equal to five tournaments distributed across five regions, because geography determines who can access them.

The third belief, and this is the one I want to stress most: a young player losing a lot does not mean they have no future. In Vietnamese youth tennis, many players are cut from centres because they lost during puberty, when the body is changing and technique has not stabilised again. These players are sometimes the ones with the best game intelligence; they simply need more time than the system is willing to give.

People call that an academy failure. I call it a layer of ground nobody has dug into.

Ending: an open question and a brick nobody has laid

I do not think Vietnamese youth tennis is in an apocalyptic state. I also do not think a miracle is about to happen. What I think is this: we have a grassroots layer broad enough to produce players, and an elite layer that is too narrow to keep them. That narrow gap will not be solved by a few more training slots, but by changing how the system records and tracks a young player over time.

Every academy is an excavation site. Every generation of players is a cultural layer. I am only the one who writes it down.

And the next brick still has nobody laying it.
