Nulla sit eight competition points clear at the top of the Macleay Valley Cricket Association first grade table after they picked up two victories in as many Twenty20 games last Saturday.
Nulla's bowlers did the job as they were able to defend their total of 182 in their opening victory over South West Rocks.
Adam Stutz (53) helped Nulla post the high total before Dan Baker and Mitch Nichols both picked up two wickets to contribute to South West Rocks falling 15 runs short of victory.
Nulla then proved they can chase just as good as they can defend a total, as they surpassed Stuarts Point/Eungai's 143 runs at the end of the 15th over.
It was a match to remember for Nulla bowler Chris Walker as he finished with eight wickets from his four overs.
Corey Crotty (68) and Shane crouch (63) combined with the bat to earn the win.
Meanwhile Rovers picked up a win in their first outing as they chased down Stuarts Point/Eungai's total of 98 in the 16th over.
However, they weren't able to match those efforts in an important clash with South West Rocks.
In a battle for second position, South West Rocks posted a total of 157 to chase but Rovers weren't up to the challenge.
Rovers were dismissed for 130, giving South West Rocks a 27 run win.
