This season's Whitney Cup minor premiership goes on the line during the next two weekends, with defending champs Rugby carrying an 8.05 point lead into the contest.

Colts got over Macquarie in their most recent clash, with captain Chris Morton saying earlier this week it was a good win considering his side had to search for quick runs in the first 19 overs of day two, after only 38 of the 75 overs were possible after the rain the previous week.

Colts batsman Brad Cox believes it will be an even contest this week, as it spells the beginning of the next two-day game against Rugby.

"It's going to be a well-contested game this week," Cox said.

"They (Rugby) have a pretty good side. We lost to them in the grand final last year and we've both played evenly this season. It's a good little rivalry we have.

"I remember last year we lost by 20-odd runs, which was pretty close. We finished up with 177 or so but couldn't chase them down. If given the opportunity this year, we want to score a few more runs against them."

Cox said his side will need to contain Rugby's 'big four' - captain Jordan Moran, Ben Taylor, Mitch Bower and Nathan Munro - while he believes the likes of his brother Tim Cox, English import Greg Buckley and fast bowler Jacob Bruce are key players for his side.

"Brucey had a few injuries this season and the best is yet to come from him. He's going to cause the Rugby batsmen a few problems, that's for sure," Cox said.

"If we bowl in the right areas, I think we're going to do well.

"We're down at Lady Cutler where the wickets have been better so far this season so ideally we'd like to bat first and make somewhere near 300 and give our bowlers a crack at them next week."
