Vospers are the hot favourites to retain the Afternoon Triples League town blue division crown and book a spot in the trophy play-offs.
All they need is 10 points from their game against Co-operative or, failing that, they need to beat rivals College Park B next Tuesday.
Vospers moved into a 15-point lead with a 36-shot win against City.
Leading the way was Peter Sansbury – with a 15-shot victory against Chris Frost – followed by Ray Porter, who earned a 12-shot win against Dave Nancarron.
Making it a full house of points was Dave Harding, who won by nine against Ken Dodds.
College Park B kept in the picture with wins against Naismith and Copnor.
Playing against Copnor on the Copnor Road green, Hugh Upward won five of the final six ends to turn a one-shot deficit into a 13-shot victory against Dave Powe.
And Ray Markwell kept smiling with a seven-shot win against Les Wilkinson.
It was not all one way as Terry Budd won by three against John Spence.
Against Naismith – also on the Copnor Road green – Clive Carter scored 10 on the final two ends to beat Mike Shepherd by 12 shots. John Spence beat Alan Cobb by 11 for Naismith and Les Watts won by five against Hugh Upward.
Cosham enjoyed a nine-shot win against Gas Social thanks to rink victories by Mike Gilbert and Gordon Lake.
In the red division, Alexandra now have a 16-point lead and only two games to play but College Park A and Star & Crescent are both still in the hunt.
College are 17 points adrift but have two games in hand.
Alexandra had a close shave as they trailed by seven with three ends to play against Cosham Red. But nine shots in the final four ends by Tom Edgerller, and a four on the final end by Tom Suthers, helped them to a nine-shot victory against the Reds.
Star & Crescent kept up the pressure with a seven-shot win against Eastney.
Rob Manning’s seven-shot win against John Johnson and a four-shot win by Mel Wilde did the damage.
Priory moved a step away from the wooden spoon with an eight-shot win against Eastney.
For Priory, Arthur Newland won by four against Brian Brown, Laurie Scott by three against Peter King and Alan Hale by one against Gerry Dobson.
Cowplain look pretty certain to retain the eastern division trophy. They require two points from their last two games against Waterlooville.
In their latest game they enjoyed a comfortable 38-shot victory against Purbrook.
The trio of Reg Barber, Fred Mant and Peter Parry won 15 of the 18 ends as they trounced Gerry Prior by 23 shots.
Bryan Franklin won by 15 against Brian Middleton.
Purbrook did rescue a point as Ted Howard tied with Alan Perry, though.
Leigh Park kept their slim hopes alive with two comfortable wins against Denmead.
Playing at Ashling Park, they won by 35 shots with Brian Haines leading the way with a 19-shot victory against Frank Lovell.
And three days later at Front Lawn Rec they beat Denmead by 42 shots.
This time Fred Miller was the hero with a 42-shot win against Ron Smith.
In the west division, Gosport a still look good for the trophy and the district play-off despite losing by eight shots to Gosport B.
