Boru reappears at Leopardstown Brian Boru is the main focus of attention as the Flat season continues to gather pace at Leopardstown on Sunday, where the St Leger winner makes his reappearance in the Alleged Stakes.Aidan O´Brien successfully used this Listed race last year to reintroduce another Group 1 performer Black Sam Bellamy but the son of Sadler´s Wells will not have things all his own way. This ten furlongs distance is short of his best plus the 7lb penalty for scoring at the top grade makes it a tough task.However Brian Boru looks the type to progress further with another winter behind him, and he should have a bit too much class for the likes of Napper Tandy and Mkuzi. The latter is fit from a spell in Dubai, while Akshar and recent hurdle winner Dawn Invasion were both useful sorts in Britain last year.The Ballydoyle team may complete a treble on the afternoon as Lucky, who showed promise on her only outing here last season, has bright prospects in the Irish Stallion Farms EBF Fillies Maiden and the well-bred All Too Beautiful, a full-sister to Galileo and Black Sam Bellamy, is another likely winner in the concluding Ashmount Maiden.There are a number of competitive handicaps on the seven race card, and Blue Away is an interesting contender in the twelve furlongs Oakfield Handicap. Pat Hughes´ charge scored three times in handicap company (2 hurdles/1 Flat) last year, and landed a tidy gamble last time out at Cheltenham in November.
