Australian pair Mariafe Artacho del Solar and Taliqua Clancy have moved within touching distance of an Olympics berth after taking out the FIVB Beach Volleyball World Tour event in Mexico.
Artacho del Solar and Clancy came from behind to beat China's Wang Fan and Xinyi Xia in the final, and now only need to go through the motions to qualify for Tokyo.
The pair collected $US20,000 ($A29,300) in prizemoney with the win, but it is the 800 Olympic rankings points which could prove the bigger prize, with the pair looking to make up for lost time after missing a large chunk of the season due to Artacho del Solar's knee injury.
They are expected to move into the top five on accumulated Olympic ranking points from ten events.
A pairing needs to compete in 12 events to meet qualifying criteria, but even with points they have already accrued, Artacho del Solar and Clancy would expect to finish in the top eight in Olympic qualifying.
The top 15 teams earn a Games berth via the Olympic rankings system.
"We didn't start well, but for us it was just about being patient, sticking to our game plan and believe we could turn things around," Clancy said after the 15-21 21-14 15-12 victory.
"To win this tournament, it means a lot for us."
It was the third straight match Clancy and Artacho del Solar had been forced to come from behind as they claimed a sixth World Tour gold medal.
Nicole Laird and Becchara Plamer finished ninth to keep their hopes of securing Australia a second berth at the Tokyo Games alive.
