Katamatite put up little resistance in the first innings of their round-12 Murray Valley Premier Division clash with top side Barooga, bundled out for 94 in just 45.1 overs.
Justin Maley ripped the batting order to shreds, taking 7-53 in 19 overs, including seven maidens and five of the top six scalps.
Bradley Parnell showed the only major resistance, scoring 30 from number 10.
Barooga is 2-81 in reply, with Jamie Stanyer out for 41.
Meanwhile, Cobram-Yarroweyah United has already taken first innings points against the higher placed Katunga and will look to push for an outright win next week.
Kane Goldsworthy took 5-14 to help bowl Katunga out for 108 before opener Kieran Andrew guided United to a first innings lead before being out for 57.
United is 7-111 at stumps.
Nathalia is in the process of dominating bottom side Finley after day one of their match.
Finley openers Daniel Hibberd and Russell Stockdale seemingly got their side off to a reasonable start, scoring 41 and 17, respectively.
However, the other nine batsmen contributed only 19 more runs between them as Ash Quinn made a mess of the middle order to take 6-24 and bowl Finley out for 80.
Nathalia then banked first innings points comfortably, despite no batsmen completely taking hold of the bowling, (Bailey Bell top scored with 25), declaring at 8-116 to have another crack at Finley before stumps.
The openers had other ideas once again, and negotiated the 11 remaining overs without loss.
Finley will resume on 0-19 with a mountainous task ahead of them to stave off outright defeat.
In the other game for the round, Deniliquin Rhinos bowled Cobram out for 149, with opening bowler Tom McGregor taking 4-23.
Taylor Pugh top scored with 42.
Deniliquin is 3-38 in reply in a match that could have finals implications, with Cobram second and the Rhinos fourth on the ladder.
Waaia has the bye.
