Racing: Aidan O'Brien looks certain to hold an exceptionally strong hand in Sunday's Derrinstown Stud Derby Trial at Leopardstown.
Macarthur has proved popular in the ante-post markets for the Vodafone Derby on June 2nd and the brother of 2005 Epsom hero Motivator is one of eight O'Brien possibles at the five-day stage.
Royal Lodge Stakes winner Admiralofthefleet could also run, along with Archipenko, Chinese Whisper, Hernando Cortes and Mahler.
Yellowstone could take his chance after finishing down the field in the 2000 Guineas while Soldier Of Fortune is due to run in the MBNA Chester Vase on Wednesday.
The remaining two entries for Sunday's Group Two test are Dermot Weld's Westlake and the Kevin Prendergast-trained Mores Wells.
While that pair are clearly outnumbered by O'Brien's team at this stage, the last-named colt proved too good for Macarthur in the Ballysax Stakes over course and distance last time.
