It turned out to be a tournament for the Ks - Konjuh won the girls event while Kyrgios beat fellow Aussie Kokkinakis in the boys. Nick Kyrgios thus strengthens his grip on the number 1 spot, having won 27 of his last 28 matches, including wins over Kyle and Liam in the Canadian Open. His only defeat since then was to champ Filip Peliwo in the US Open.
