No decision on So You Think pilot Aidan O'Brien believes there is no rush to decide who will partner So You Think in the Coral-Eclipse at Sandown on Saturday. The son of High Chaparral is a multiple Group One winner in Australia and was sent off at long odds-on for the Prince of Wales's Stakes at Royal Ascot after having won his first two starts in Ireland in impressive style. He suffered a narrow defeat at the hands of Rewilding under Ryan Moore, but the five-year-old is likely to need a new pilot this weekend, with Moore set to ride Derby and Arc hero Workforce for his boss, Sir Michael Stoute. "We're looking at the Eclipse, but we'll see how he is at the start of the week and we'll sit down and chat about it," O'Brien told At The Races. "Joseph (O'Brien) rides him out every day, Seamie (Heffernan) rides him in all his work, and Seamie rode him the day he won the first time at the Curragh. "I don't think there's any scarcity of riders, so we'll decide if he's going to run or not first and then we can talk about who is going to ride him. "We're delighted with him and everything has been good since Ascot."
