Monarto has edged ahead of Mannum on the Murray Towns A grade ladder as the two sides continue their seemingly inevitable march towards a grand final match-up at season's end.
Only Mypolonga appear likely to play the spoiler at this stage, two wins back in third place, with all other teams well below that.
Between them, the Black Caps and Roos have half of the competition's top-10 run-scorers and wicket-takers.
But neither looked like a powerhouse in winning their Saturday matches.
Mypolonga v Mannum
Mannum needed 49 overs to surpass Mypolonga's score of 6/187 at Mypo, and they lost eight wickets chasing it down.
The home side had a few good partnerships up and down the order during their innings, which Jason Daniell finished off with an unbeaten 56 off 36 balls batting at seven.
Jayden Krollig was Mannum's most successful bowler, with 3/28.
In reply, the steady loss of wickets would have had the visitors sweating a little, but Zakk Bullard steered the side to victory as he scored 87 not out, with Dwayne Krollig soaking up pressure at the other end for much of that time.
Adam Eckermann took 3/35 for Mypo, while Aaron Zrim and Jared Marston claimed a couple of victims each.
Monarto v Meningie
At Homburg Oval, the lethal bowling of Tyson Bradley was not enough to get the visitors over the line.
Bradley took sole possession of the association's wicket-taking lead with 5/21 off 10 overs, including four of Monarto's top five.
But the Black Caps, seven down, were still able to limp to their target of 158 in the 36th over, with Brad Lienert 44 not out at the close.
Earlier, Lienert (2/39), Harry Miles (2/18) and Harrison Webb (2/34) had restricted Meningie to 8/157 off their 50 overs.
Joseph Zadow batted out most of the innings before being dismissed for 80.
Wanderers v Tailem Bend
Stingy would be the word to describe the Woo Hoos' bowling, which kept Tailem Bend to 100 runs off their full 50 overs.
James Dawson was like a shooting gallery sideshow operator at Murray Bridge Showground: in the firing line, and surrounded by ducks.
He made 54 as six of his teammates failed to get off the mark.
The Eagles were never in it at 4/8 and 6/32.
Sam Robinson walked away with the sensational figures of 4/8 off 9.5 overs, while Jalen Kowalick took 4/20 off 10.
However, Wanderers made some work of the chase, losing three batsmen for single figures before reaching 6/101 off 27 overs.
Ryan Morris top-scored with 30.
