The Dukes moved into a share of the lead after defeating Hello Kitty 3-2.

The teams shared the honours over the four singles matches, resulting in the overall win for The Dukes.
In the other match-up, Peralandra picked up its first win of the season, getting the best of Dragons 3-2.
Raymond Kissell had to go it alone for Dragons, drafting fill-ins to cover his absent teammate.
In the match of the tie, Kissell snatched the win in a five-set battle with Jimmy Greenwood, giving his side the opportunity to seal the match in the doubles.
Dragons led 2-1 in the crucial rubber, but Peralandra took three close games 11-8, 11-9, 11-9 to take it 4-2.
