O'Brien dominates Chester Vase possibles Aidan O’Brien is responsible for five of the 11 entries for the Boodles Chester Vase on Wednesday. The Ballydoyle handler has saddled a record nine previous winners of the recognised Derby trial. Ruler Of The World landed the Group Three prize in 2013 before going on to claim Epsom glory, while Wings Of Eagles was second four years later prior to springing a surprise in the premier Classic. This season the Ballydoyle handler has entered Anchorage, recent Dundalk winner Changingoftheguard, Cork scorer Shark Bay, Craven Stakes fifth Star Of India and United Nations for the feature event on day one of Chester’s May meeting. Charlie Appleby could be represented by impressive Newmarket novice winner New London and/or Natural World, who made a successful start to his career at Newbury earlier in the month. Michael Bell’s Dillian, the Andrew Balding-trained Berkshire Royal and Duke De Sessa from the Irish yard of Dermot Weld also feature. Subsequent Epsom heroines Light Shift (2007) and Enable (2017) are among the previous winners of the preceding Weatherbys Bloodstock Pro Cheshire Oaks. O’Brien has Lily Pond and Thoughts Of June in the mix for the Listed contest, while son Joseph could saddle runaway Leopardstown winner Above The Curve. Bell’s Improvise could carry the colours of the Queen, George Boughey’s Mystic Wells could turn out just over a week after scoring at Brighton and Hello Jumeirah, trained by William Haggas, may bid to build on the promise of her recent debut win at Kempton. Proceedings get under way with the ICM Stellar Sports Lily Agnes Conditions Stakes. Likely contenders for this five-furlong dash includes Gay Kelleway’s Ocean Cloud and David O’Meara’s Star Of Lady M, both of whom are unbeaten in two starts. Plenty of attention might also be on the Edinburgh Gin Maiden Stakes, the penultimate event on the card. Featuring among the 19 possibles for the extended mile-and-a-quarter event is the O’Brien-trained Waterville. The Camelot colt was a mover in the Derby market prior to being sent off at odds on at the Curragh earlier this month, where he was third.
