Cork preview Brendan Brackan and Sruthan, second-placers in the last two renewals of the Listed corkracecourse.ie Navigation Stakes, return in search of more in the extended mile contest today. In 2013 Brendan Brackan had to yield by a length and a quarter to Rich Coast, when going off the 6-5 favourite, while 12 months back Sruthan also headed the market but he proved half a length inferior to Sun On The Run. On another occasion at the Mallow venue, Brendan Brackan did manage to get the job done when comfortably taking the 2014 running of the Listed Platinum Stakes. Brendan Brackan is not the only previous Cork winner in the line-up, as Flight Risk, from the yard of Jim Bolger, trainer of last year's winner, Sun On The Run, took his maiden on the corresponding programme last autumn. Meanwhile, on her opening effort for Aidan and Joseph O'Brien at this course 23 days back, Akira landed a three-runner affair to position herself well for the rise in class. The ratings say this five-runner heat should provide an exciting spectacle and the field is completed by three-year-old filly, Corail. She was equipped with a hood in the past and is now tried in blinkers. Action begins with a classy sprint handicap at 1.50. The Ticket Sales Online-titled six furlong contest has a regular from this race in Bubbly Bellini (won it last year, third in 2011) topping the weights. Talented 10Ib claimer Killian Leonard helps to offset Bubbly Bellini's 10st 2lb burden, and it would not surprise were Ado McGuinness' great old campaigner to make a bold bid again. The Coolmore Most Improved Maiden could be one of the most informative races of the day, with four newcomers among the nine participants. Moonlight Magic, for Godolphin and Jim Bolger, is an eye-catching son of Cape Cross, but maybe Ballydoyle's Successor can show the benefit of a Galway seventh placing from early September.
