Abergavenny moved one step closer to promotion on Saturday after defeating Cardiff Central at Blackweir.
Skipper Leach won the toss and elected to bowl first looking for early wickets however only one wicket fell in the first 25 overs as Cardiff Central struggled against tight bowling from the Aber attack.
The wicket to fall was to opening quick Dan Cooke who bowled well without much luck but managed to bounce out the Central opener.
Fellow opening bowler Ross Melrose also bowled a very good opening spell beating the bat on numerous occasions.
Leg spinner Sam Clarke bowled his 10 over spell for just 15 runs as the Central batters continued to score slowly. Skipper Leach brought himself into the attack and quickly claimed the second wicket with Khassan Ilyas falling LBW for 43.
Wickets then started to fall at regular intervals with Leach also bowling Sadique for 41 while Chai Sanapala claimed two wickets in a four over spell.
Central went from 123-5 to 129 all out as Leach claimed the last four wickets to fall thanks to some good catching in the ring from Burkitt, Clarke and Cooke to finish with figures of 6-21 from his 10 overs.
In reply Aber started positively in their chase of 130 knowing that a win would effectively promote them to Division One as second were playing third.
Openers Bevans and Jones ran well between the wickets while Jones punished anything short. However, Jones fell caught and bowled for 11 with the score on 17 and that brought Will Glenn to the crease.
Glenn played positively hitting through the line of the ball when he could attack the straight boundaries and again running well with Bevans between the wickets putting on 60 before Bevans fell for a well made 29.
77-2 soon became 77-3 as Gareth Burkitt fell to a great catch at slip first ball but Daniel Cooke made sure there would be no collapse as he smashed 36 not out off just 25 balls with three fours and two sixes to help Aber ease to their target in 30 overs.
Will Glenn finished up 47 not out also and 19 points were in the bag to take Aber 16 points clear of second placed Cardiff Gymkhana and 30 clear of third placed Rogerstone with just three games to go.
A win next week at Avenue Road against Lisvane will officially secure promotion back to Division One at the first attempt and be just reward for the young Aber side who have started to show their potential.
