Pires attempts to continue Tony Martin's excellent run of form in the Water Towers Chase at Ballinrobe.
The nine-year-old was an expensive failure at the Galway Festival but the conditions of this two-mile-one-furlong event means he is in receipt of 10lb from Far Away So Close, Laganbank and Tribes And Banner.
False Economy could be a big danger. He caught the eye when staying on into fifth behind Pires' stable companion Ted Veale on the level at Bellewstown last week.
Darroun is a smart hurdler when on song and Willie Mullins switches his attention to the larger obstacles for the first time in the Ballinrobe On Course Vets Beginners Chase.
Once a useful juvenile, he scored at this venue two runs back and will take all the beating with a clear round.
His jockey Ruby Walsh teams up with Martin on Galloping Gander in the Corrib Oil Handicap Chase.
He is high enough in the weights in this sphere and will do well to get the better of Claragh Native and recent Tramore victor Why But Why.
Martin has claims of Flat glory as he pitches his Galway winner Woodsophiesmile into the Jenning Meats Handicap.
Pat Flynn's Prince Chaparral is in great heart, following up a Tramore Flat success over timber there just three days later, and he heads the shortlist for the David Heneghan Memorial Handicap.
A mile and a half was too far for Granny On Fire at the same meeting and she will appreciate the test of the Breaffy House Resort Rated Race considerably more.
Last year's Beresford runner-up Orgilgo Bay has been most disappointing this term and returns from a summer holiday.
He runs in the opening Ballinrobe Racecourse Of The Year Maiden, in which John Oxx's well-related newcomer Ebaniya is among the competition.
