Israel's Sagi Muki has won his second successive International Judo Federation (IJF) World Tour gold medal with victory at the Havana Grand Prix in the City Sport Coliseum.
Estrada finished fifth in Miami last year, which will host a Grand Prix event on alternate years to Havana, and was performing well with the support of his home fans, however, the final proved a step too far for the under 73 kilogramme competitor as he was thrown for ippon with just 31 seconds on the clock.
Georgia's Tbilisi Grand Prix winner Nugzar Tatalashvili ensured he would not travel home empty handed as he beat Brazil's Baku Grand Slam bronze medallist Marcelo Contini in a battle of shido penalties to take the first bronze medal.
The second bronze was won by Russian Musa Mogushkov who defeated Dirk Van Tichelt of Belgium by a waza-ari score.
Georgian world number one and world silver medallist Avtandil Tchrikishvili was victorious in the only other men's competition of the day, the under 81kg event, as he beat the United States' Travis Stevens in a repeat outcome of the Tbilisi Grand Prix final.
Despite immense pressure from the American, Tchrikishvili struck first with a ko-soto-gari for waza-ari and held on to claim the trophy and vital ranking points towards Rio 2016 qualification.
Another Russian bronze was won by Qingdao Grand Prix runner-up Murat Khabachirov as he disposed of Brazilian Victor Penalber by ippon with just 95 seconds left of the match.

It took just 78 seconds for Germany's Samsun Grand Prix bronze medallist Martyna Trajdos to secure the first bronze medal as she threw Austria's Kathrin Unterwurzacher with an uchi-mata for ippon.
Maricet Espinosa gave the home fans a reason to cheer in the second bronze medal final as the Miami Grand Prix bronze medallist bested Israeli world champion Yarden Gerbi.
Germany's world silver medallist Laura Vargas Koch reigned supreme in the woman'sunder 70kg contest as she defeated Austrian European Championships bronze medallist Bernadette Graf with after an intense two-minutes of action.
