Mehmas was represented by his 22nd stakes winner on Tuesday when Dha Leath landed the Listed Pipalong Stakes at Pontefract.
The five-year-old mare, one of 14 stakes winners from the first crop of Mehmas, made the trip from Gavin Cromwell's stable worthwhile by staying on well under P J McDonald to win the day's feature event by a length from Espressoo.
"She's a little warrior," McDonald told Racing TV. "She's not very big and Gavin wanted a bit more rain for her and the draw was tough. I thought we'd have to be brave on her, but as soon as she got one gap, she took them all and flew home.
"I knew when the pace wasn't quick early we'd have to go and attack the front, but I hoped we wouldn't get there too late. I got a bit of room on the bend and I had a willing partner under me. She's done her job now."
Owned by Gerard Clarke, Mrs J P Duffy & Garvan Donnelly, Dha Leath was bred by Bernard Cooke out of Tarried, an Observatory relation to the top-class Juddmonte runners Wemyss Bight and Beat Hollow.
