Dermot Weld and Pat Smullen were quick out of the blocks at Gowran Park, claiming both divisions of the Irish Stallion Farms EBF Maiden.
Treasure Map got into the first division as a reserve and made the most of the opportunity, hitting the lead early in the straight and staying on well to hold Mount Nelson by a length.
'It was a good performance. He's a progressive two-year-old and will make a very nice three-year-old,' said Weld afterwards.
The master of Rosewell House described Thiella as 'very classy' after she made a winning debut in the second division of the contest.
Smullen sent the Kingmambo filly to the front over a furlong from home and she proved much too strong for hot-pot Red Rock Canyon (4/11f), coming home a cosy length-and-a-quarter victor.
'She's a very nice well-bred filly. That will be her for the year. She's very classy and there is a lot to look forward to next year.'
Flexible Friend was well supported to give the duo a treble in the mile maiden later on the card but could only finish sixth.
La Conquistadora proved a game winner, holding the persistent challenge of Soldier Of Fortune in the final furlong to prevail by the narrowest of margins.
Jim Bolger, who also bred the Aidan O'Brien-trained runner-up, will aim the winner at the Listed Eyrefield Stakes at Leopardstown on the last day of the season.
Star Inside notched a hat-trick when running out a game winner of the feature event on the card.
Kevin Prendergast's charge fought doggedly to hold the late challenge of Temlett by a short-head in the ITBA (South East Region) EBF Nursery.
The Key Of Luck gelding was also involved in a tight finish last time when dead-heating at Listowel and Prendergast said: 'It's better to have a lucky horse than a good horse!'
The easiest winner of the day was undoubtedly Farinelli in the Siromer Tractors Ireland Maiden.
Mick Kinane didn't have to move a muscle as the Sheikh Mohammed-owned gelding cruised through to lead two furlongs out and sauntered clear for a six-length victory.
'The jockey's biggest concern was if he would get paid his fee for that!' joked trainer John Oxx.
'Last time he was slowly away out of the country stalls and he hasn't run for a while as we've been waiting for the bigger metropolitan stalls, so he can load last. He's in the sales at Goffs but I might try and get another race into him before that.'
The connections recorded a double when Film Festival claimed the Uvex Racing Goggle Handicap. The Diesis colt had to survive a stewards enquiry after runner-up Eastern Bloc found himself short of room in the final furlong.
Kyles Bay was another reserve to score when claiming the Derrinstown Apprentice Handicap. Winning jockey Billy Lee got among the doubles when Tommy Stack's charge Hoffman turned the concluding Newpark Hotel Handicap into a procession.
