The underdogs Waimate upset Pleasant Point to cause a log jam at the top of the Hamersley Cup table at the end of the first round.
The Mud Dogs remain on top despite their 29-7 loss at Manchester Park but only two competition points separate the top four teams.
Waimate also remain in semifinal contention just two points outside the top four and will be a real threat in the second round.
It was a huge defensive effort that got Waimate home with some big first-up tackles that stopped Pleasant Point’s momentum.
No 8 Loni Toumohuni was outstanding in defence and was one of Waimate’s try scorers along with Matt Hayman, Richard Ford and Jamie Engelbrecht.
Lock Jarrod Hayman was another standout in a well drilled pack while the inside back combination of Theo Davidson and Kurt Rooney excelled.
Up 19-0 at the break, Waimate kept the pressure on to ensure the competition leaders would not make a comeback.
For Pleasant Point lock Grant McKerchar impressed as did first five Bryce Shearer, who made a couple of good breaks.
