Gowran Park preview Hans Holbein is set to make his eagerly-awaited debut in the Irish Stallion Farms European Breeders Fund (C & G) Maiden at Gowran Park on Sunday. The Aidan O'Brien-trained colt is a Montjeu half-brother to Irish St Leger hero Sans Frontieres and is engaged in the Racing Post Trophy. Joseph O'Brien takes the mount in a 16-runner affair over a mile, with Ballydoyle also represented by Kilimanjaro (Colm O'Donoghue) and the unraced Aloft (Seamie Heffernan). Of those to have seen the track, the Dermot Weld-trained Aared looks the danger, having found only O'Brien's exciting Ol' Man River too good at the Curragh last month, going under by three-parts of a length. He was eighth on his first run in a race won by John F Kennedy and appears to be going the right way. Victory in the opening Irish Stallion Farms European Breeders Fund Fillies Maiden for O'Brien's mount Together Forever would be another boost for Jessica Harrington's Jack Naylor, who had her in third last time out in a Listed race at the Curragh. Together Forever should be hard to beat but, in a big field, the likes of John Oxx's Sea The Stars debutant My Twinkle will be worth a look. Donnacha O'Brien gained his first victory in the saddle when Quartz struck at Dundalk a fortnight ago and the pair are reunited for the gowranpark.ie Rated Race. The half-brother to Kingsbarns attempts to put an end to Coolfighter's winning spree, while Waydownsouth is also in fine fettle and seeks a hat-trick. First Sitting was behind two subsequent winners when fifth at the Curragh and Weld's colt will be high on most shortlists for the Powerstown Stud Maiden. The master of Rosewell is represented by Keyboard Melody, who tries to make amends for letting favourite-backers down the last twice in the Gowran Golf Memberships For 2015 749 Euro Apprentice Handicap.
