Miss McHenry goes on from One Boss© Photo Healy Racing
Ger Lyons' Miss McHenry ground it out in tough conditions in the opening claiming maiden over an extended seven furlongs at Bellewstown.
The track was firmly in the teeth of Storm Agnes with the ground riding heavy.
Miss McHenry tracked the leaders and was ridden by Colin Keane to challenge One Boss a furlong and a-half from home.
The 7/4 shot grabbed the lead at the furlong pole and forged on by a length and three-parts from 11/8 favourite One Boss.
Assistant trainer Shane Lyons said: "Sure is survival of the fittest!
"She ran over a mile and a-quarter before, so we knew that would stand to her. That's the minimum trip that she wants.
"She goes on the ground, she is by Starspangledbanner, and would like that ground.
"If she is not claimed, she should get another over a mile and a-quarter. If not, she could be one for summer jumping. She is in to be claimed."
There were no claims in this race.
