Waringstown joined Lisburn at the top of the Premier League table with a huge victory over defending champions Instonians at The Lawn.

James McCollum proved to be the match-winner with his 118, more than twice as many as the next best batter in the match.

The Ireland Test player faced 129 balls but hit only five fours and four sixes as he built his crucial innings.

Coming to the middle after Ross Allen, replacing the holidaying Adam Dennison at the top of the order, was out in the fourth over he stayed until the start of the 47th over, when he gave Andrew White his third wicket.

Tom Mayes, with whom he had added 73 for the sixth wicket, was there until the end, hitting a vital 51 not out from 35 balls with two fours and three sixes.

Neil Rock started in a hurry, with six fours and a six in his 38 from 27 balls but he played one rash stroke too many and skied a return catch to Steve Stolk. The Waringstown professional then forced Cade Carmichael to play on, just after bringing up his half-century and when Shane Dadswell was run out by Stolk in the next over, Instonians were struggling on 157 for five.

But Instonians, as befitting the champions, bat deep and despite Greg Thompson taking the next three wickets, Cian Robertson (32) and George Craigan (20) got the visitors within 20 runs before Stolk had Craigan caught in the deep to complete victory.

Next Saturday, Lisburn visit The Lawn.
