Martin's favourites set for Pierce Psycho and Robin Du Bois will represent trainer Tony Martin in the Pierse Hurdle at Leopardstown on Sunday while Davy Russell has been confirmed as rider of Psycho. Both Psycho and Robin Du Bois are vying for favouritism in the race and Martin said: "I'm very happy with Psycho and Davy Russell will ride him while Robbie [Colgan] will probably ride Robin Du Bois. Both of mine will appreciate a bit of cut in the ground so conditions should be okay on the day. "I also have Mourne Rambler in there, but I'd say this race is probably coming a bit too soon after Ascot for him so he probably won't run, although we'll see how he goes in a piece of work on Thursday first before we up make our minds."
