Wagga City took an important step towards securing their finals berth but face another crucial test on Saturday.
Goalkicking proved to be the difference as the Boiled Lollies took a 28-22 win over CSU to keep a six-point buffer over Ag College in the battle for fourth place.
The two Wagga rivals clash at Beres Ellwood Oval this weekend and City coach Rob Cleland is hoping they keep up their momentum.
"It was a win that we needed to get so it was quite pleasing," Cleland said.
"It was a tough game but we got there in the end."
The two teams went try-for-try at Conolly Rugby Complex on Saturday as Sarah Deaner crossed for the winner for Wagga City.
Kellie Allcorn kicked all four conversion attempts while only one of CSU's four tries were converted.
Ag College come into the clash after a 46-10 win over Tumut.
Cleland expects another tight contest.
"They nearly got us last time so we have to make sure we're ready for them," he said.
Meanwhile the top-of-the-table clash proved to be a one-way affair.
Unbeaten Griffith responded to being held to a draw by Waratahs in impressive fashion, scoring seven unconverted tries to take a 35-0 win over Albury at Murrayfield on Saturday.
Waratahs moved around Albury and into second place after a 58-0 victory over winless Hay.
However Albury and Wagga City have a double points game to come.
