Excellent day for O'Brien
Excelebration made the perfect start to life with the Aidan O'Brien stable when easily winning on his seasonal debut at the Curragh.
A Group One scorer for Newmarket-based Marco Botti but three times put in his place by the brilliant Frankel, Excelebration had no trouble taking the Big Bad Bob Gladness Stakes.
The 2-7 shot cruised past his pacemaking stablemate Windsor Palace just inside the final furlong in the hands of the trainer's son, Joseph.
He pulled away fairly effortlessly to score by three and a quarter lengths from Croisultan who stuck on to take second place.
"He's lazy at home and we weren't 100% sure, but he was doing well in his half-speed work with Joseph," said O'Brien.
"Joseph rode him at the Curragh a month ago and was very happy with him. He said he gave him a proper feel, travelled very well and quickened very well. We're looking forward to his next run now."
Excelebration will now go for the JLT Lockinge Stakes at Newbury on May 19 when he could face Frankel once more.
"The plan was to come here then go for the Lockinge if everything went well. I'd imagine that is what we'll be looking at now," O'Brien went on.
"Everyone knows what Frankel is, an incredible horse. We're delighted with the way this fellow ran and look forward to the next day.
"He was a very good horse last year. Physically he's very well made. He's done very well over the winter and you couldn't be happier with his first run."
O'Brien enjoyed a treble on the card but it was not without a surprise as Requisition (7-2) floored his stablemate Nephrite in the Anne Brewster Memorial Loughbrown Stakes.
Seamus Heffernan made all the running on O'Brien's supposed second string, who was well-backed late on, and the Invincible Spirit colt kept pulling out more when challenged in the closing stages.
Nephrite, the 4-9 favourite, found disappointingly little and had to settle for third place with Coolnagree taking second spot, a length and three-quarters behind.
O'Brien said: "Requisition progressed well from last year. He got a mile well in Galway when he won his maiden.
"Looking at him you wouldn't think he'd get a mile. He is a very straightforward horse to train.
"We'll have a look at some of the Guineas with him, maybe an Irish or whatever, something like that.
"We'll wait and see. He stayed the seven really well here."
Of Nephrite, who looks set for a return to sprint trips, the trainer said: "He won his maiden here over six furlongs and he wasn't sure to get a mile. He has lots of speed but he was just found out on the ground."
Infanta Branca (1-3) gave her sire Henrythenavigator his first winner when landing a straightforward victory for the O'Brien team in the Irish Stallion Farms EBF Maiden.
Runner-up on her debut at Cork two weeks earlier, she made the most of her experience as she made all the running to beat Leitir Mor by half a length down at the line.
O'Brien said: "She is very fast and exciting. Like a lot of our other Henrythenavigator two-year-olds she has his speed. We always thought a lot of her. She will go for the Marble Hill Stakes next.
"Joseph said she could be a Queen Mary filly."
Chrysanthemum was never headed as she outpointed her rivals in the Run Kildare 13th May Alleged Stakes.
The 5-4 favourite, ridden by Wayne Lordan, followed up her course success over a mile by keeping Vivacious Vivienne at bay by a length and a half to win for the first time over 10 furlongs.
"We knew there wouldn't be much pace, so we decided if there was no pace she'd jump out, not go too quick and dictate away and see what happened," said trainer David Wachman.
" There are loads of races for her now and she might go for the Victor McCalmont Stakes at Gowran now."
Aklan (16-1), one of five John Oxx-trained runners in the Irish Stallion EBF Maiden, made a winning debut in the hands of Ben Curtis, beating his stablemate Ebazan by a short head.
Cnocan Diva, the 7-2 favourite, survived a stewards' inquiry to land the The Irish Field Handicap for trainer Tommy Stack while Kevin Prendergast's Ansaab (2-1) also struck for favourite backers in the Finlay's For Volvo Handicap.
