Mohammadi defeated Abror Atabaev from Uzbekistan 5-1 in the final of 72kg.
Mohammadi was awarded the par terre in the first period and he hit a front headlock which was scored two and one more point was awarded for a stepout. But Iran challenged, claiming four points on the throw, which was confirmed on review but the stepout point was removed as it was a push.
After the challenge, Mohammadi led 5-0 and when Atabaev was given par terre in the second period, Mohammadi defended that position with ease and went on to win the gold medal.
Iranian Greco-Roman wrestlers Gholamreza Farokhi and Fardin Hedayati had previously won two gold medals in the event.
