Cootamundra made it three straight wins in the Group Nine leaguetag competition with a crucial result against Southcity on Sunday.
The 22-8 victory ensures they keep themselves in the thick of the finals race.
Kangaroos remain in fifth place after a 22-4 win over Gundagai due to their vastly superior percentage but Cootamundra are hot on their heels and also jumped three points clear of Southcity.
Meanwhile Brothers gave Young a reality check with a 30-0 win at Alfred Oval.
The Cherrypickers had won seven straight to move into third place, but the premiers proved far too strong on Sunday.
They face another big test up against ladder leaders Temora this week after the Dragons made it 10 from 10 with a 24-8 win over Albury.
Cootamundra could move into fifth if they can take a win over eighth-placed Gundagai on Sunday with Kangaroos facing a touch challenge up against Brothers, who have lost just once so far this season, on Saturday.
In the other games Temora faces off against Young while winless Junee face Albury.
