Having thrashed second-placed Acomb last week, Hunters the estate agent York and District Senior League premier division leaders Dunnington took out third-placed Woodhouse Grange where they won by six wickets in the 48th over.
Nick Hadfield provided the Grange's infrastructure with a solid 60, while Howard Johnson made 27 and Steve Burdett 30 as Steve Precious claimed 4-57.
The innings was topped off in swashbucking style by Tom Quinn whose unbeaten 25 off just nine balls took Woodhouse to 185-6.
In reply, Hamid Khan made 32, Dave Greenlay 35 and Harwood Williams 31 before Collis King made a seasonal best of 66no to see Dunnington to a six-wicket win.
Acomb took the same points as the leaders from their win at Heworth and remain nine points behind.
Paul Mosey 33 and Jonathan Draper 34 made runs for the Elm Park side but Dave Sykes grabbed his second seven-wicket haul in three weeks as he took his seasonal total to 39 with 7-36 as Heworth fell to 130 all out.
Martin Sigsworth hit back with 3-40 but Chris Simpson made 25 and Acomb sealed the win at 133-7.
At Sessay, home batsman Nick Harrison made the only three-figure score when he took an unbeaten 109 off a Clifton Alliance attack headed by John Hunter (3-72). With Steve Frare making 37 and Chris Till 35, Sessay took tea content with a total of 244-4.
But their satisfaction soon evaporated as Aussie Luke Wells led the Clifton reply with 96.
Hunter underlined his value to the team by making 45 and Simon Dwyer added 26. But Richard Musgrave was the hero as his unbeaten 49 steered Clifton to a five-wicket win with an over to spare.
Osbaldwick travelled to Easingwold without the services of skipper Steve Young and all-rounder Dave Thompson, who have both been suspended by the League following a disciplinary hearing, but they came away with an honourable draw.
The home side amassed 231-9 as Martin Robinson 32, Paul Skilbeck 26, Dan Copeland 44 and Paul Redshaw 48 revelled in the sun.
Shaun White's 3-88 was the best showing by an Osbaldwick bowler before Mark Thompson 25 and Ed Baldwin 45 took Os' to their ninth draw of the season at 158-7.
First division leaders Sheriff Hutton Bridge were thwarted by the last two Whitkirk batsmen who held out for four overs to nick a draw.
The Bridge's batsmen were again in good form with Paul Oldfield making 70 at the top of the order before three wickets fell rapidly.
Steve Crowder then made a fine 90 before sacrificing his wicket in the team's cause towards the end of the innings and Dave Gilbertson made a handy 36no to see his side to 235-7 as Harlon Haye took 3-42.
Whitkirk got of to a poor start as early wickets fell but rallied through Neil Edgecock 31 and Darren Grey 37.
Spinners Danny Snowball 3-54 and Oldfield 3-29 were given good support by their fielders who held a series of catches but teenager Tom Clarke dug in to make an unbeaten 30, finding an ally in last man, 16-year-old Gary Fawcett ,who survived the last four overs to help Whitkirk draw at 158-9.
Tadcaster Magnet were able to reduce the Sheriff lead to 27 points when they won a high-scoring game at Crayke by three wickets.
Mark Hutchinson hit 96 and Andrew Dawson 71 in a 147-run second-wicket stand which helped Crayke reach 217-4.
But their efforts were countered by Chris Malthouse 43, Russ Parker 53, and Paul Clark 47, who overcame the threat posed by Mike Raper's 5-22 to post a Magnet haul of 220-7.
Duncombe Park took the unusual step of opting to bat first when they won the toss against promotion-seeking York II and no doubt felt the decision was justified when they got the better of a draw.
Mark Wilkie smashed a run-a-ball 49 in a partnership of 70 with Brian Leckenby who went on to make 81 as Park totalled 231-8. Aussie Nash Stone took 3-54 for York but made only a minimal contribution with the bat.
However, Dave Catlow 59 and Andy Kay 39 put York in a strong position before four suicidal run outs in the closing overs almost handed the game to the home side.
Paul Wilkie's 3-38 added to York's problems and they had to thank their last pair who held out for nine balls to earn a draw at 194-9.
Eighteen-year-old Anthony Knowles was the star in the Hull Zingari side, following his 4-49 with 61 as his team beat Stamford Bridge by six wickets.
Matt Beckett made 61, Peter Milner 52 and Phil Hill 33no as Bridge reached 195-7 before Knowles combined with overseas ace Rob Elston 69 to seal victory.
