Sophia Dunkley scored an unbeaten 119 to lead England to a decisive 114-run triumph over Ireland in the final one-day international at Worcester.
The match concluded the series with England taking a 3-0 clean sweep, marking their third consecutive victory against the Republic of Ireland this summer.
Dunkley's innings was built on a partnership of 73 runs with Maia Bouchier, who contributed 39 before retiring earlier in the day.
Following Dunkley's dismissal, England lost six wickets for just 31 runs in the final stages of their chase, falling short of a record total they had targeted.
All-rounders Freya Kemp and Dani Gibson were among England's remaining batsmen, with Gibson reaching an ODI-best 41 before the collapse began.
Kemp was dismissed for 23 after being caught at long-on, while Jodi Grewcock and Alice Capsey were also removed in the latter part of the innings.
This match represents the final game of England's international summer schedule, which includes an unusual context regarding their opponents.
The series has seen Dunkley and Bouchier each achieve a century, providing a significant opportunity for both players after Tammy Beaumont's departure.
England's bowling attack faced limited opposition in this match, with the visitors managing only seven boundaries throughout the innings.
The outcome confirms England's dominance in the current series format, while Ireland's campaign ended without a single point.
