The Mexican will now compete in the last online event of the season on November 17 having won the women's competition while Kazakhstan's David Degtyarev made it a third straight victory in the men's event to also guarantee a spot in the finals.

Launched by World Para Powerlifting in April, the Online Series gave athletes the opportunity to compete virtually during the COVID-19 pandemic.

These lift attempts were judged remotely by technical officials, with the results being based on a formula that provides a score based on athletes' different body weights.

After winning two consecutive events, Russia's Vera Muratova had to settle for second behind Perez, in a repeat of the second event in the Series, which produced the same result.

Perez's 126.34 trumped Muratova's 119.46 - but both lifters will make the finals.

Another Russian, Anastasiia Mamadamirova finished third with a score of 110.58.

In the men's competition, Degtyarev finished with a comfortable 204.74, dominating the field as Kazakhstan also topped the country rankings for the event too.

Colombia's Jainer Cantillo finished on a score of 186.12, just defeating his compatriot Fabio Torres on 184.67 to secure second and his place in the finals.

Perez, Muratova, Degtyarev and Cantillo will be joined by the other four best-ranked athletes in the Online World Cup Finals.

In the final competition, the male and female athletes will face each other in a mixed event and the action will be live on World Para Powerlifting's Facebook page.

The fifth event also saw the end of the Team Captain competition, a virtual challenge in which four Para powerlifting experts predicted the athletes' results in each Series.

Perez was the winner again for Team Blue, topping the rankings ahead of Italian Alessandro Boraschi's Team Yellow.

Brazil's Pedro Meloni finished third for Team Green and Egyptian Sherif Osman's Team Red ended in fourth.
