Anastasia Gorbenko Swims 52.11 at CSL Match 1: Reading a 'Top-3 All-Time' Number Correctly

At 11:47 p.m., I was still rewinding the last four lanes. The 25-yard pool of the American collegiate system does not have the roaring stands of an Olympic final. Only the starting beep, the sound of feet slapping water, and a scoreboard flashing 52.11.

Anastasia Gorbenko touched the wall. She did not raise her arms. She looked at the board, then turned to her coach. The way a swimmer who is used to winning looks at a scoreboard is always different from someone winning for the first time.

52.11 seconds in the 100 IM — individual medley — short-course yards, at CSL Match 1. According to the published report, that is the third-fastest performance in the history of the event in short-course yards. And it was her first time swimming the event.

But "first time" here needs to be read carefully. Gorbenko already owns a European medal in the 100 IM in a 25-metre pool. So "first time swimming this event" almost certainly means first time in the 25-yard format, not the first 100 individual medley of her career.

That distinction is not a matter of semantics. It determines how the whole result should be read. If it were her career-first 100 IM, 52.11 would be an anomaly. If it is merely her first in a 25-yard pool, this is a story about format conversion — more plausible, and remarkable in a different way.

The format decides everything

In the United States, the collegiate system races in a 25-yard pool, not 25 metres. Short-course yards — SCY. World Aquatics, the sport's global governing body, does not ratify world records in this format. Every "all-time" label in SCY is tracked by the swimming community itself, not by any official body.

That does not make 52.11 less valuable. It only places the number where it belongs.

A 25-yard pool is just under a metre shorter per length than a 25-metre pool. A short-course 100 IM covers four lengths: butterfly, backstroke, breaststroke, freestyle. Three turns, three wall push-offs, three underwater phases. In a 50-metre pool, a swimmer gets only one turn over the same distance. The difference sits right there: short course rewards those who are strong at push-offs, underwater work and fast transitions.

I learned to read a lane through the eyes of the swimmer starting in the outermost lane — the one the media mentions least. In short course, that swimmer is often the best technician at the turn.

A proven swimmer

Anastasia Gorbenko is not an emerging phenomenon. She is an Israeli national-team swimmer who won bronze in the 100 individual medley at the 2026 European Short Course Championships — SCM, short course metres, a 25-metre pool. She competes for Louisville in the American collegiate system.

This is a pattern I have seen repeat many times in my career: an already-established international swimmer enters the American collegiate system and converts to SCY almost instantly. SCM is a 25-metre pool. SCY is a 25-yard pool. The two formats are structurally close — the same number of turns, the same premium on underwater technique.

That is why technique explains most of the conversion speed here. Based on my experience covering American collegiate meets, swimmers moving from SCM to SCY whose very first result already sits at the top of the list rarely win through raw swim-out speed. They win through turn technique and underwater work.

At 28, after twelve years observing this sport from many angles — from a children's pool in Vietnam to a sports newsroom in the United States — I have drawn one conclusion. The most noteworthy thing in a swimming report is usually not the biggest number, but the smallest detail that gets left out.

Three women in the top 10 on one night

Bella Sims — 52.69, sixth all-time in SCY. Caroline Larsen — 53.05, tenth. All three on the same evening, in the same pool.

A single night producing three top-10 historical swims in the same event usually says two things. First, that pool was fast — cool water, suitable depth, or swimmers coming off a taper phase. Second, and more important to me: the "all-time" list for the short-course 100 IM is a thin dataset.

The 100 IM is not an officially scored event in the NCAA championship system. It is swum at team-format meets where organisers log the times. That means its historical list is built from invitationals and dual meets, not from a standardised database. Far fewer swimmers have ever raced this event in SCY than the 100 freestyle or the 200 individual medley.

So "third all-time" here is literally accurate. But it is not equivalent to "the third-fastest woman in history over 100 medley" in any absolute sense.

And this is the detail I consider most important in the original report: the two swimmers faster than 52.11 in history are not named. No names, no times, no context. The reader cannot judge the gap between Gorbenko and the top of the list.

That is an information gap, not a minor oversight.

What is missing: split data

In swimming, the final time is only a starting point. What tells the story is the split sheet — the time of each length.

In the short-course 100 IM, the third length is breaststroke and the fourth is freestyle. The decisive point usually lies in the breast-to-free transition and in the final sprint. Without splits, an analyst cannot know which length made Gorbenko fast, which length cost her time, or how she closed.

The original report provides no splits. That means every technical conclusion in this piece must stop at the level of conditional inference.

The same applies to reaction time off the start and underwater data. Also absent.

With a report that supplies only a final number, what I can state with certainty is this: 52.11 is international-class speed, in a format for which she already had compatible foundations, and in an event she was swimming for the first time.

The contrarian angle: the real value lies elsewhere

The media value of 52.11 lies in the speed. The true competitive value lies in the ability to convert formats.

Gorbenko's SCM background explains why she was fast on her first attempt. But the conversion skill itself is the long-term asset. In the cycle toward Los Angeles 2028, swimmers who convert well between formats will hold an advantage in scheduling and training load.

There is a paradox few mention. Precisely because SCY records are not ratified, results in this format tend to be over-read by the public and under-read by the system. One side sees "top 3 all-time" and assumes an absolute peak. The other sees a mid-season team meet that carries no official championship points.

The truth sits in between. This is an early-season form signal, not championship-final form.

One more detail stands out in the report: the CSL scoring system includes a "jackpot" mechanic — a swimmer who beats an opponent by a set margin takes that opponent's points. That mechanic is tied to the model of the International Swimming League, a team-format competition that ceased operations. A collegiate league reusing that model is a signal about how the sport is being repackaged. But that is a story for another piece.

The story is not over

Bella Sims 52.69. Caroline Larsen 53.05. Anastasia Gorbenko 52.11. One night, three women, three places inside the historical top 10 of a single event.

Behind those numbers are women who refuse to stop — in a season when the media devoted almost all its space to men's competitions.

The real answer to what 52.11 means will arrive in the next long-course season, when Gorbenko swims the 100 and 200 individual medley in a 50-metre pool. That is when the true competitive value of this form will be tested.

For now, an event that carries no championship points and no ratified records has just gained another name in third place.
