Reaction of placed Derby connections US Army Ranger fared best of the Aidan O'Brien Investec Derby quintet, finishing second behind Harzand as Irish-trained colts swept the board at Epsom. The 7-2 favourite was settled towards the rear of the field before rocketing home, but he was held a length and a half at bay by the winner at the finish, with his stable companion Idaho third. O'Brien said of the runner-up: "He ran a great race and I'm delighted for Dermot Weld and the Aga Khan. He was a bit babyish early on, but we're not making any excuses. We'll see how the horse is and we're looking forward to running him again." The Ballydoyle handler added: "Idaho ran very well in third and I think he'll come forward again, too. We'll see how we are and plan things as we go along." John Gosden's Dante hero Wings Of Desire was best of the British in fourth. Gosden said: "The horse has done us proud. He's done nothing wrong. "It was a bit rough out the back, but he got a nice run down the straight, but it was not his ground. "He will be better on better ground, but he's learning a lot. "The first three really appreciated the ground and the winner was very smart. "We'll look towards the Curragh (Irish Derby), if it dried up, but we won't be going to Ascot for the King Edward, which was our original plan."
