Irish skipper Laura Delany led from the front as Leinster beat Phoenix by 75 runs in the opening round of the Women's Senior Cup.
'Dellers' hit nine boundaries as she top scored with an unbeaten 66 from 45 balls as her team ran up their record total in T20 games - 212 for 3.
The innings had been given a flying start as Sophie MacMahon and Ellen Ridgeway (23) shared an opening stand of 72.
MacMahon cleared the ropes twice in her 64 from 39 balls, also hitting eight fours as she and Delany added 60 for the second wicket.
There was no respite for the Phoenix attack as Jenny Sparrow (33) and Delany added a further 78 in seven overs to set the daunting total.
The Phoenix chase was always an unlikely one, despite the best efforts of Lara Maritz and Ireland's newest international Georgina Dempsey (21).
Maritz struck ten fours in her unbeaten 78 from 66 balls - Phoenix ending 75-runs adrift on 137 for 6, with a wicket apiece for Katie Dillon and Ava Canning, plus four run outs.
It's obviously brilliant to start the season off with a win, especially with the first game being a cup game with so much weighing on it," said Ireland captain Laura Delany afterwards.
"Sophie and Ellen got us off to an absolute flyer. They were absolutely brilliant in the power play, and provided a really good platform for myself and Jenny, to keep the run rate up and accelerate in the closing overs. That's our highest total in T20 cricket for us and just short of the record I believe. I thought we fielded and bowled well.
"Fair play to Phoenix, I thought they battled bravely. Lara and Georgina batted well for them, and for a young side they have a lot of potential. I was really impressed by the way they approached and performed in this game because a lot of their players wouldn't have played any matches.
"We obviously have a few involved in the Super Series, so we probably had a head start.
Overall I was happy with our performance, although we have a few things to work on, but it's great that we are through to a semi-final."
Elsewhere, Merrion ran out emphatic nine-wicket winners over Malahide.
The villagers were dismissed for just 78 with Sadbh Breslin picking up three wickets and two apiece for Niamh McNulty and leg-spinner Celeste Raack.
Leah Paul's undefeated 41, coupled with 27 from Rebecca Stokell saw the Anglesea Road side ease to the comfortable win.
It was far from one-sided in the game between The Hills and Clontarf.
The Castle Avenue side posted 108 for 2, with Christina Coulter-Reilly (43) and Anna Marshall (34*) sharing a second wicket stand of 74 after Aoife Brennan had made 10.
Ireland squad member Jane Maguire's unbeaten 32 kept the Milverton side in contention, supported by double figure contributions from Katie Boylan (16*) and Miranda Andrews (12).
Clontarf skipper Emma Butler's 2 for 8 proved crucial though and ensured her side progressed to the semi-finals with a nine-run victory.
