O'Brien completes double with a 1-2 Trainer Joseph O’Brien completed a double at Killarney today when his well backed Grey Waters landed the Seamus Mulvaney Bookmakers 3-Y-O Hurdle under jockey Shane Shortall. The daughter of Mastercraftsman was backed from 5/1 this morning in to 11/4 at the off and in the end battled well to beat stablemate Pronounced and adding to the earlier win of another stablemate High Language in the fillies’ maiden. Trainer O’Brien wasn’t present but afterwards Shortall stated “she ran very well the last day against Brutal where J.J. (Slevin, jockey then) felt he maybe should have made a bit more use of her. I went out with that in my head today and forced the gallop a bit and kicked on. “She did it really well in the end and won cosy enough. She jumped very well and was like a handicapper over the last two. “I started working with Joseph (O’Brien) full-time two months ago and things are going really well and he’s after giving me two winners already. It’s a very good job and they’re very good people to work for.”
