Double world champion Megumi Horikawa has put Japan in control of the International Judo Federation (IJF) Grand Slam in Tashkent.

Horikawa prevailed in the women's under-63-kilograms competition to give her country a second gold medal in Uzbekistan's capital.

She also won her individual and team world titles in the city last October.

The 27-year-old defeated Prisca Awiti Alcaraz of Mexico with a crushing ippon after just one minute and 53 seconds.

She was already heading to victory with an earlier waza-ari but it did not matter.

A golden score victory came for Szofi Ozbas in the bronze medal-match against France's Agathe Devitry after the pair went into the sudden death stage with a single waza-ari each.

Olympic silver medallist Michaela Polleres then picked up the second and last women's title of the day.

The Austrian was locked in a gruelling battle with Croatian Barbara Matic in the under-70kg decider before finally taking the win in 6:33 with a waza-ari.

Prior to that, Anna Bernholm of Sweden delivered a stunning ippon on Germany's Giovanna Scoccimarro just four seconds before the end of normal time.

Home favourite Murodjon Yuldoshev then beat Kazakhstan's Shamshayev with a single waza-ari in normal time in the men's under-73kg final bout.

His compatriot Shakhram Ahadov failed to join him on the podium after missing out on bronze to an ippon finish from Magdiel Estrada of Cuba.

Attila Ungvari of Hungary picked up gold in the men's under-81kg with a six-minute win over Shamil Borchashvili of Austria.

An all-Uzbek battle then took place between Muso Sobirov and Sharofiddin Boltaboev for the bronze medal.

It did not last long, however, as Sobirov threw his countryman to the ground for a 27-second ippon victory.

Competition is due to continue tomorrow with the women's under-78kg and over-78kg events as well as the men's under-90kg, under-100kg, and over-100kg.
