Boesmans and de Groot, who sit in 41st position in the world rankings, topped the podium in just their seventh international tournament together after winning the International Volleyball Federation four-star event with a 23-21, 19-21, 15-10 success.

"We had played them in pool play and we knew how good they are," said De Groot who teamed up with Boesmans for the first time in March.

"We had to bring our top game to win.

"We kept our calm near the end and kept playing our game and focusing on our side of the net.

"I believe it was an amazing match to watch and I still can’t believe we won it."
