Ballydoyle quartet bidding for Derby glory Aidan O'Brien has four chances to register an astonishing 12th success in Saturday's 150th Dubai Duty Free Irish Derby at the Curragh. Qualify, a shock 50-1 winner of the Investec Oaks at Epsom, has been a late addition to the Classic picture, but t he number one hope on jockey bookings appears to be French Derby runner-up Highland Reel, with Ryan Moore riding on the crest of a wave following his astonishing week at Royal Ascot. Colm O'Donoghue keeps the ride on Qualify, while Epsom Derby fourth and sixth, Giovanni Canaletto and Kilimanjaro, are partnered by Joseph O'Brien and Seamie Heffernan respectively. O'Brien said: "Highland Reel will step up another quarter of a mile but we were happy with him in France last time and we've been happy with him since. "We always thought she (Qualify) was a really nice filly and we always knew the minute she went beyond a mile, there was the possibility she would really step up and Epsom was the first time she went beyond a mile. "We were obviously delighted with that and look forward to Saturday. "Giovanni Canaletto is in good form. We felt Epsom was maybe coming a little too quick for him, but he came out of the race well and we look forward to seeing him run again on Saturday. "Kilimanjaro ran a nice race at Epsom and the Curragh might suit him better than Epsom." Dermot Weld's unbeaten Radanpour takes a big step up in class after winning each of his three starts this season, completing the hat-trick in Leopardstown's King George V Cup at Listed level three weeks ago. Big-race jockey Pat Smullen said: "He'd probably want a drop of rain and hopefully they'll keep plenty of water on as he just wants a bit of ease in the ground. "It's definitely a big step up for him, but he's been very consistent and deserves to take his chance. "It's an open race, but if the favourite (Jack Hobbs) turns up with his run from Epsom, he'll be hard to beat. "We're all hoping for a good run, but on the figures Radanpour has to improve a lot."
