Valley remains top dog in the Citizens Shield after running riot against the defending champion.
Its 57-14 thrashing of Kurow on Thursday night, played earlier to allow players to attend the opening weekend of duck-shooting, was its fourth win from four games.
Excelsior is nipping at its heels, however, having won three in a row after beating Maheno 34-19.
In the only match played on Saturday, Athletic Marist came agonisingly close to beating Old Boys, going down 24-21.
It was a physical encounter in which three yellow cards were handed out in the first half and it seemed you could not go five minutes without a break in play for an injured player.
Athies dominated early but fell behind 10-0 after Inoke Fisilau spotted a penalty and winger Elian Coan scored a long-range try off a wayward Athies pass.
Halfback Tini Feke burrowed his way over from a metre out to further extend the lead to 17.
A penalty try got Athies on the board after a player was taken out trying to chase a kick in behind the Old Boys defence which resulted in a sin binning.
Athies then took advantage of their numerical advantage and scored through midfielder Osea Qamasea to cut the lead heading into the sheds.
Old Boys struck first in the second half after some beautiful interplay and offloads between both forwards and backs put Feke over for his second.
A few moments later, a clearance kick from Old Boys failed to find touch and Malakai Tobiau strolled over to make it a three-point game with less than five minutes to go.
A 50:22 kick had Athies attacking just 10m out from the Old Boys line.
As they spun the ball wide, one final draw and pass put Saia Fifita in a gap and he dotted down in the corner for the match-winner.
But, that fateful pass was ruled to have gone forward and, with time up, the game ended in an Old Boys win.
The 9-10 duo of Feke and Fisilau were standouts for Old Boys.
For Athies, Tobiau provided a tonne of juice off the bench.
In the Thursday night fixtures, Valley walloped Kurow to remain top of the table.
The Weston club side ran in eight tries and dominated.
Meli Kolinisau was at his barnstorming best while wingers Asesela Ravuvu and Tony McCone were rarely taken down by the first defender.
Halfback Jake Matthews showed his versatility by shifting into blindside flanker for the second half.
Excelsior has now won three on the trot after beating Maheno away from home in a a tightly contested match.
It appeared to be game on when prop James Hill crossed the line to cut the Blues lead to eight points with less than 15 minutes to play, but the electric Matia Qiolevu continued his outstanding start to the season with another try to seal the win for Blues.
