Zoe Brown broke the Northern Ireland pole vault record for the fourth time this year when she won Tuesday's competition at the Cork City Sports.
Brown, building up the Commonwealth Games in Glasgow, added two centimetres to her two-week-old record to set a new figure of 4.42m.
The 30-year-old Antrim athlete is now ranked second in the Commonwealth list behind Australia's Alana Boyd.
Brown narrowly failed to clear 4.50m in windy conditions at the Cork meeting.
She beat several major names including Kylie Hudson of the USA, who cleared 4.68m earlier in the season, and Tori Pena who recently represented Ireland in the European Team Championships in Tallinn.
