Sir Isaac Newton returns at Dundalk The reappearance of the smart Sir Isaac Newton in the Dundalk Stadium Race will prove interesting and he features as one of six runners on Monday's card for his trainer Aidan O'Brien. The Galileo colt showed a good level of ability as a three-year-old last year and while unsuccessful in two Group races, did fill sixth spot in the Jersey Stakes at Royal Ascot. The full-brother to Ralph Beckett's top-class mare Secret Gesture faces just three rivals but is opposed by the once high-class Yuften. Now in the care of Johnny Murtagh, the one-time second-past-the-post in the Group One Prix Jean Prat ran with credit on his Irish debut here last month and will also be suited by a step back up to this seven-furlong trip. Champion trainer O'Brien begins with Lundy and Caravaggio in the opening juvenile maiden, where the American-bred latter is aided by his inside draw. The aforementioned Murtagh will be hoping his Kasbah can land a hat-trick in the Irishinjuredjockeys.com Handicap, having won on his latest starts at Wolverhampton in October and this venue in March. Kasbah races from a career-high mark of 95 but should again prove competitive. The concluding Crowne Plaza Dundalk Race & Stay Handicap sees another hat-trick chaser in action, with Claire Cannon's Coreczka bidding to defy a rise in the ratings, having won twice at this venue in recent times. Coreczka's chances are again helped by Oisin Orr's useful 7lb claim.
