National hero scores on Who's That Grand National winning jockey David Mullins was on the mark at Limerick today, steering the Liam Cusack trained Who's That to win the Coral.ie European Breeders Fund Mares Chase. The pair got the better of 8/11 favourite Definite Ruby on the run-in, for a half length win. Afterwards Cusack stated “it was such a good prize, we had to go for it and these races (for mares) have to be supported. I breed a few myself and have had nothing but fillies but there's a good programme for them. “She also won a nice pot at Leopardstown and I'm delighted for her owner David Cornwall, who also bred her and has a few of her relations.” By Tom Weekes
