Veteran Liamin finished fifth at the Rio 2016 Olympics and teamed up with 23-year-old Myskiv in May following a strong campaign last year.

So far the duo have enjoyed three fifth-place finishes and they began their Mexican assault on the four-star Beach World Tour event with an 18-21, 21-18, 15-13 victory against Dries Koekelkoren and Tom van Walle from Belgium.

"It's been amazing to play with him,” Myskiv said ahead of the tournament at Plaza Bicentenario.

"He’s [Liamin] got experience in the Olympics and the World Championships and has also been pretty successful in his indoor career. 

"He's always talking with me during training sessions and matches and I feel that it helps me a lot to improve."
