Andy White's half century helped Instonians to a narrow two-run win over CSNI and ensured their place in the semi-finals of the Lagan Valley Steels T20 Cup.
White hit 5 fours and six in his 59 from just 41 balls to help the Shaw's Bridge side to 152 for 6.
He shared a third wicket stand of 53 with Shane Getkate (28) after Ollie Metcalfe and Murray Commins fell early.
James Hunter thumped two sixes in an enterprising 34 and those runs were to prove vital in the final analysis.
The CSNI reply always looked on track with Andre Malan at the helm, but despite him making an undefeated 78 from 56 deliveries (6 fours, 3 sixes), they fell two short on 150 for 4.
New face in the Inst ranks, South African seamer Josh Manley impressed with 1 for 13 in his four overs, while Ben Rose (1-8) also impressed.
In Group A, CIYMS beat Waringstown to secure a home draw against Instonians in the last four.
Allen Coulter (pictured above) was the hero with bat and ball, hitting a breezy 36 from just 17 balls (2 fours, 3 sixes) as his side made 131 for 8 - Obus Pienaar (28) and Nigel Jones (24) also in the runs, while Jacob Mulder took 3 for 11.
Coulter then bowled Adam Dennison in the first over of the reply, and with James Cameron-Dow (2-21) accounting for Greg Thompson and Kyle McCallan, the holders fell 20 runs adrift.
Friday night's dead rubber games between Lisburn and Carrickfergus and Muckamore and North Down were both washed out.
