Waringstown Women completed back-to-back doubles with a 30-run win over title challengers Holywood in what was a de-facto Premiership decider at Seapark.

Batting first, Abbi Harrison raced out of the blocks with a flurry of boundaries, but the hosts fought back thanks to their South African-born Netherlands international Madison Landsman.

The leg-spinner bowled a superb four-overs spell, claiming three wickets for just six runs as Waringstown slid from 42 for one to 66 for five.

Harrison found a willing ally in teenager Penny Speer and the pair sensibly steered their team towards the hundred mark. Opener Harrison eventually fell for a top score of 44 (six boundaries), but Speer shepherded the tail to what would prove a defendable 120.

Alexandra Atkinson also claimed three scalps, while there was one wicket apiece for Erin Bond, Nina Kerr and Lara Maritz.

The chase was a tense one in the first 10 overs of the reply with Amy Caulfield striking twice to dismiss Holywood openers Eva Cupitt and overseas player Landsman.

Irish international Lara Maritz soon unfurled her powerful repertoire of strokes as she raced to 36 from 22 balls (five fours). However, her dismissal by left-arm spinner Speer proved the turning point.

From 68 for two in the 12th over, Holywood lost their last eight wickets for just 22 runs to be all out for 90.

Rachel Harrison took four wickets for 11 runs, while Amy Caulfield finished with three for 13 in a superb effort by the Waringstown bowling unit, who have been exceptional all season.

“I was happy when we had put 120 on the board as I knew if our batters were struggling to score on the pitch, it would be the same for Holywood,” said delighted Waringstown captain Sophie Hinds after collecting the Premiership trophy.

"We are all absolutely buzzing having achieved back-to-back doubles. It’s some achievement for this group.

We have been together for the past two years and our togetherness and consistency as a group has certainly paid dividends. We and all our coaches have worked hard and it’s great to have that rewarded with trophies.

“They are great to captain as they always give 100 percent. It’s just like playing with your best friends and that togetherness allied with our enjoyment has been key to the success. It’s been really great for the club.

“Although we have a lot of young players coming through, we also have a nice balance with some very experienced players like Amy Caulfield, Charlotte Lyons and Naomi Matthews — who I suppose are relatively young but have played an incredible amount of cricket in that time. The youngsters have really benefitted from playing alongside players of their calibre.”

Hinds also paid tribute to Penny Speer, with the left-arm spinner being the breakthrough performer for the Champions.

“Penny has been phenomenal with the bowling this year, taking wickets every week with remarkable consistency. She has been a real asset for us and, despite her youth, has shown nerves of steel in pressure situations which is great for a captain to be able to call upon. We were so happy for her today in that as well as her batting she got crucial runs.

“It’s been a remarkable season and it’s great that it’s been a real team effort with everyone chipping in. We were helped by the return of Abbi Harrison from her knee injury, while New Zealander Abigaile Gerken was also a wonderful addition to the squad. They’re wonderful to have around with their enthusiasm and dedication.”

Waringstown have an opportunity to make it a treble as they are through to the Final of the All-Ireland T20 Cup in two weeks’ time when they face a very strong Merrion side who have won the competition twice before.

That decider is at Stormont on Sunday, August 31.
