Champion jockey Joseph O'Brien partnered his first winner on Laytown strand when Sister Slew took the Marquees Nationwide Claiming Race.

The Gordon Elliott-trained mare was sent off 9/4 favourite in the seven furlong contest and tracked the leaders in the early stages.

O'Brien sent her to the front going to the two pole and despite running around a touch in front she kept on strongly to post three-length success over Like Magic

“It's something different and it's nice to ride a winner here. Gordon was quite confident she would win today and he was spot on,” said O'Brien.

“She travelled away fine and probably got to the front a bit sooner than ideal but my rhythm was taking me there so I had to stay going.

“In fairness to her she stuck it out to the line.”

O'Brien revealed afterwards that Tramore is the only track that he has yet to partner a winner at in Ireland.

Sister Slew was claimed for €5,000 by Martin McManus, while Stoichkhov was reclaimed by connections for same price.
