NORTH Down had to change something to get back that winning feeling and it worked in spectacular fashion, with a terribly under-strength Instonians on the receiving end.

Professional Ruhan Pretorius, a regular opener for his franchise in South Africa, went in first with Daniel Graham yesterday and 39 overs later they had added 231 chanceless runs.

Both completed centuries, Graham batting through the entire innings for a career-best 126 not out while Pretorius fell for 124. Between them, they hit 33 fours and five sixes.

The fastest scoring of the day came from Alistair Shields, who faced just 38 balls and was out in the last over for 75, having hit 11 fours and two sixes as North Down finished on 352-2.

Instonians threatened a glorious chase for 20 overs when they were 138-2 but the introduction of Ryan Haire into the attack and a crazy run out which cost skipper Andrew White his wicket for just two ended the game as a contest.

Elsewhere, Muckamore took advantage of an under-strength Civil Service North to move into joint third place in the Premier League with three wins as the top two, Waringstown and CIYMS, claimed easy victories over Armagh and Carrickfergus respectively.

Marc Ellison (33) was in the runs early on but four wickets for Karthik (4-39) and two apiece for Fahad Iqbal and Adita Adey had the Stormont side in trouble.

Half centuries in a 5th wicket stand of 95 between Chris McMorran (65) and Morgan Topping (56) saw CSNI recover to post 217.

Muckamore had no trouble chasing down the target as half centuries from Adey, Iqbal and Adam McDaid - the latter a midweek signing from Eglinton saw them record a six-wicket win.

It was a similar tale at Belmont where Pat Botha's 68 saw Carrick make 222 - Pat Botha top scoring with 68 and Allan Coulter taking 4 for 37.

Chris Dougherty (94) and Nigel Jones (86*) shared a second wicket stand of 154 as CIYMS eased to the win.

Jamie Rogers (76), Shadley van Schlalkwyk (43) and Neil Gelston (35) were all in the runs as Armagh posted 235 for 9 at The lawn - three wickets each for Lee Nelson and Shaheen Khan.

James Hall (61), Lee Nelson (54*) and skipper Greg Thompson (51*) all scored 50's as the home side cruised to victory with 10 overs to spare.
