The final in Ulaanbaatar turned on patience. On 19 June 2026, Balabay Aghayev stood across from Ryuju Nagayama, the reigning world champion, and won gold in the men's -60 kg at the IJF Judo Grand Slam. The performance was measured rather than loud. It confirmed the Azerbaijani as the world number one.
The final
The bout carried weight beyond the medal. This was the first qualifier of the road to the Los Angeles 2028 Olympic Games, the point at which four years of accounting begin again. Aghayev met the moment with restraint. Against an opponent of Nagayama's pedigree, he did not force the contest. He read it. He controlled the grip exchanges, denied the Japanese fighter his rhythm, and let the tactical picture come to him rather than chasing it. It was the judo of a fighter who trusts his preparation.
The victory sat at the head of a day that otherwise belonged to Japan across the lighter categories. In that context, beating the world champion in the -60 kg final was the day's outlier — a single, deliberate act of resistance against the run of results. Aghayev supplied it.
The trajectory
The number one ranking is not a coronation so much as a confirmation. Aghayev arrived in the Mongolian capital already at the top of the -60 kg order, and the win in the cycle's opening event settled any question about whether the seeding reflected form. To defeat the reigning world champion at the first qualifier is to state the case in the plainest terms available to a judoka: on the day that mattered, against the man holding the title, he was the better fighter.
For a lighter-weight competitor from Azerbaijan, a nation with deep judo roots, the result marks a clear step. The country has long produced fighters in the heavier divisions; a world number one at -60 kg carrying the flag into a new Olympic cycle is a different kind of standard-bearer. The win in Ulaanbaatar does not complete his story. It opens the next chapter of it, with the LA2028 ledger now bearing his name at the top.
There is a particular composure in winning without spectacle. Aghayev's final was decided not by a single moment of drama but by the accumulation of small, correct decisions. That is the mark of a mature fighter, and it is the quality he will need to carry across the two years of qualifying that now stretch ahead.
He came to Mongolia as the world number one. He left having proved it.
