Buchanan spoils Yazdani’s return at Zagreb Open

By Vinay Siwach

ZAGREB, Croatia (February 5) -- For the modestly attended Zagreb Open 2026, Thursday brought a noticeable lift in attendance as Hassan YAZDANI (IRI) returned to competition.

Yazdani, who injured his shoulder in the Paris Olympics final, was returning 18 months and another surgery later. The Olympic champion at 74kg in 2016 and silver medalist at 86kg in 2020 and 2024, is now up at 97kg.

Over the past decade, Yazdani has enjoyed stardom with fans not just in Iran but across the globe.

So when a bulkier Yazdani walked out to the mat in Zagreb, his silhouette under the spotlights looked different. The 13 kilogram jump was clearly visible. There was no traditional jump from him before coming to the center of the mat.

Yazdani’s decision to switch Olympic weight classes was a move born out of necessity, especially after two shoulder surgeries.

In the early rounds of the Zagreb Open, the experiment seemed to be working. The signature underhooks were there, the gas tank seemed fine and his movement, despite the bulk, did not seem unnatural.

Before reaching the final, Yazdani had seen off his opponents with rather ease. He scored points via stepouts, takedowns and go-behind in typical Yazdani fashion. He gave up only four points in his three bouts and reached the final without much trouble.

But then he hit a wall.

In the second period of the final, Yazdani's underhooks stopped working and his gas tank showed a leak. His movement became slower although his mind wanted him to be quick against Stephen BUCHANAN (USA).

Buchanan matched Yazdani for position and let Yazdani take only a 2-1 lead at the break. But he caught Yazdani in the second period and launched the Iranian for a suplex for four. It's rare for Yazdani to be thrown around like that.

And with him falling behind 5-2, Yazdani tried to attack more and that's when opportunities for Buchanan opened up as he scored three takedowns and two steps, beating Yazdani 13-3 and capturing the gold medal in Zagreb.

This was Yazdani's only tenth loss at the senior level and first to a U.S. wrestler other than David TAYLOR (USA). It was also the first a wrestler defeated Yazdani via technical superiority.

With Buchanan's gold, the United States finished the tournament with five gold medals in Freestyle.

World champion at 92kg Trent HIDLAY (USA) forfeited his final against Mobin AZIMI (IRI). But Hidlay had defeated the Iranian 5-5 in their round robin bout.

Hidlay, known for his insane comeback in bouts, was down 5-0 against Azimi when he mounted a comeback. He scored a takedown and then a point to make it 5-3. He then scored a step out on Azimi which cut the lead to 5-4. Iran challenged the stepout call but lost it to tie the score 5-5 with Hidlay holding criteria. Hidlay then defended his criteria for the rest of the bout.

In another bout against an Iranian, Hidlay came back from 8-0 down to beat Abofazl RAHAMANI (IRI) 11-9 as he took the top spot in his group.

Rahamani and Azimi clashed as well in the round robin and it was Azimi who scored a takedown in the final seconds to beat his compatriot 4-3 and finish second in the group.

At 125kg, Shamil SHARIPOV (BRN) is quickly emerging as the biggest challenger to world champion Amir Hossein ZARE (IRI) at the weight class.

Sharipov captured the gold medal at 125kg with a incredible cradle and turk position against Wyatt HENDRICKSON (USA). Shapirov locked Hendrickson in a leg-turn and then turned him on his back, keeping him down and securing the fall.

With a dominant performance in Zagreb, the Bahrain wrestler has put his name as a serious medal threat at the 2026 World Championships that will be held in Bahrain in October.

European silver medalist Zelimkhan KHADJIEV (FRA) defended his gold medal from 2025, winning a close 4-4 final against Dean HAMITI (USA) at 79kg.

Khadjiev was leading 4-1 when he was put on the activity clock. As the clock expired and he failed to score, Khadjiev also gave up a takedown which tied the score 4-4. But the French wrestler get the criteria due to his two two-point scoring moves.
