Tuamhain makes the breakthrough on fourth start for O'Brien Tuamhain made the breakthrough on her fourth start for Joseph O'Brien, as she ran out a comfortable winner of the Callan Handicap. Previously trained by Kevin Prendergast, the daughter of Mayson was placed on her last two starts at Naas and Cork respectively. Owned by the Wait For Us Syndicate, the bay three-year-old opened on-course at 13/2 this afternoon, before going off the 5/1 favourite under Shane Crosse. Settled behind the leaders, she was third approaching the straight, and was pushed along to lead from the furlong pole. She was ridden and extended her advantage in the closing stages, going on to score by three and a half lengths. Ishigati (6/1) finished second under Declan McDonogh for Dermot Weld, while Aubineau (8/1) and Villa Maria (8/1) completed the placings in third and fourth. Crosse, who was recording his fifth winner in as many days, said afterwards: "The plan was just to get her settled in behind one or two. She jumped very well and I got a bit of cover, and turning into the straight she was going the best of them. "I think I probably still got there a bit too soon but to be fair to her she kept at her game and put it to bed easy. "In her two-year-old career she was a sprinter and we have changed her now that she stays a mile well. She finishes off that last furlong like a sprinter which is great.” Additional reporting by Alan Magee
