The two sides at the top of the table will meet on Saturday evening when Diggers and Coro clash under lights at Exies Oval.
Heading into the top of the table clash the two sides are level on points with the Cougars currently occupying top spot due to a superior percentage.
Diggers' skipper Theo Valeri knows the importance of this clash heading into the finals rounds of the regular season.
"It is a huge game given where the two sides are," he said.
"They are probably one of the favourites to be there at the end of the season alongside us.
"We know that we will be playing them at the later stages of the season so it would be good to get a positive result this weekend."
Both sides will be heading into this weekend off the back of big wins and will be looking to continue their streak moving into the final six games of the regular season.
Diggers are on a two-game undefeated streak after falling to Leagues just before Christmas while the Cougars have picked up two bonus-point wins in as many weeks.
The sides have a pretty good understanding of how each other play with the key players on both sides playing representative cricket together, Valeri knows you still need to be at the top of your game no matter how well you know the opposition's strengths and weaknesses.
Last weekend saw the first hundred hit by Diggers' Trevor Richards and Valeri was pleased to see Richards finding his form.
"I think that he knows his game that well and that is why he is so hard to get out once he is set," he said.
"He is one of our key players, so it is great to have him in form."
This weekend will see a number of the top performers in the first grade competition go head-to-head.
The top four batsmen, comprised of Theo Valeri and Richards from Diggers and Dean Bennett and Haydn Pascoe from the Cougars, will battle it out and Valeri knows how important claiming his opposite number will be.
"Haydn is definitely a key wicket for them," he said.
"Not only is he dangerous with the bat but with the ball as well.
"Two Sundays ago (representative game against Temora) was the best that I have seen him bowl so we will have to work hard to keep him out if he comes on."
Diggers will be welcoming back Dean Crack who will come in to replace Luke Peruzzi while Dean Villata may also return to the side after missing the last couple of games.
The first ball in the top of the table clash will be bowled at 4.30pm on Saturday.
