Champion Trainer Aidan O'Brien completed a treble at Naas today when his American import Darwin made an impressive Irish debut in the Boston Access Race.

Ridden by the trainer's son Joseph (completing a double on the day), the strapping son of Big Brown was held up last of the three runners before quickly moving to the front over a furlong out, for an easy two and a quarter lengths win over Fighter Squadron

O'Brien Snr wasn't present but Joseph O'Brien later stated “he has been an exciting horse and is still only a three year old. He's still quite green, that was his first run on grass and it was his first time on a track like this. He hasn't done much at home and has only been on grass twice since we've had him, so they're probably the only times he's been on grass.

“He hasn't run in nearly a year and got hurt on his second run in America before having a break. He's a lovely horse and is in races like the Sussex Stakes.”
