Second ODI, Belfast
England 320-8 (50 overs): Beaumont 150* (139); Sargent 2-60
Ireland 45 all out (16.5 overs): Raymond-Hoey 22 (37); Cross 3-8, Filer 3-10
England won by 275 runs
Tammy Beaumont's sparkling 150 not out helped set up England's 275-run thrashing over Ireland in a one-sided second one-day international in Belfast.
The hosts were bowled out for just 45 - their lowest ever ODI total - in reply to England's imposing 320-8.
Opener Beaumont batted throughout for her 10th ODI century - the most by any Englishwoman - with support from Freya Kemp, who bludgeoned 65 from 47 balls.
In reply, Ireland slumped to 8-4 inside the fourth over of their chase in a calamitous start and they failed to recover, handing England their biggest ODI win in terms of runs.
Captain Kate Cross continued her fine form, taking 3-8 after her career-best 6-30 in the first ODI on Saturday, while Lauren Filer's pace proved too much for Ireland as she finished with 3-10.
Only opener Una Raymond-Hoey reached double figures, contributing 22 from 37 balls as the gulf between the two sides was astonishingly stark.
Off-spinner Georgia Davis made her international debut, following the five debutants in Saturday's opener, and finished with an impressive 2-19, while Kemp also claimed two.
The victory also sees England secure a series win, with the third ODI taking place at the same venue on Wednesday, which is followed by three T20s in Clontarf, Dublin.
Beaumont and Cross are England's most experienced players in the England squad to take on Ireland, with a separate side named to that travelling to the United Arab Emirates for the T20 World Cup next month.
And while Cross starred in the series opener, Beaumont was frustrated to miss out at the top of the order and batted with her trademark swagger and confidence here that showed she was determined to put that right.
At times, she had to dig deep when batting with England's new faces like Hollie Armitage, Paige Scholfield and Mady Villiers, absorbing pressure and guiding them through some spells of tight bowling.
But in the destructive Kemp she found her perfect companion as they added 101 for the fourth wicket.
The all-rounder is one of only two of the squad in Ireland to also be heading to the World Cup (alongside Bess Heath), and found some form at the perfect time with her first ODI fifty coming from just 37 balls.
The knock included seven fours and two sixes, allowing Beaumont to accumulate in the middle overs, before an explosive finish saw her go from her century to 150 in just 22 balls.
While England's side is generally inexperienced, Beaumont is an established world-class performer and showed that when at her very best, she is a formidable match-winner.
