London Maccabi Vale have clinched promotion to Division Two of the Chess Valley League after a convincing victory at home to West Herts.
And a win against Chingford next week would clinch the Division Three title for Vale.
A seven-wicket triumph, led by Mark Landau's magnificent unbeaten 105, enabled LMV to secure their sixth win in eight league games, powering the club to a remarkable fourth successive promotion.
From competing in the seventh tier not long ago, an achievement representing an unparalleled period of success in the club's history.
Vale were expected to struggle in Division Three this season, but their performance at Rowley Lane against West Herts last Sunday typified the side's battling qualities and highlighted just why they have coasted to success with a game to spare.
Steven Allweis, the league's leading wicket-taker, struck early on to add to his tally for the campaign and Vale's dominance was established when Joseph Greenwall Cohen's bullet throw from the deep resulted in the run out of the other opening batsmen.
West Herts refused to buckle, however, and their overseas Australian professional struck the ball nicely to guide his side to a strong position, before he was undone by a superb piece of fielding from Allweis to fall for 78.
His dismissal was the catalyst for LMV to reassert their grip on the game and the spin duo of Adam Brand and Adam Spooner bowled accurately and with guile to take four wickets between them. Their efforts resulted in the visitors falling from 130-3 to 161 all out.
Vale's strength throughout the campaign has been their batting, and this encounter proved no different. Despite the early losses of Greenwall-Cohen and Brand, a dominant century partnership between Landau and Spooner broke the backbone of the chase.
Landau was brutal on anything short and crashed a series of leg-side boundaries, while Spooner was content to play the supporting role, occupying the crease and allaying any fears of a middle-order collapse.
There were almost 10 overs to spare when Landau hit the winning runs, an enormous six taking him to a well-deserved century and taking LMV to the next division.
