Emperor Of The Sun led home an Aidan O'Brien one-two in the extended mile maiden at Galway.

The 4/6 favourite broke well to lead and was tracked by stablemate Delta Dawn with Gatwick Kitten close up in third. Whatsallthatabout blew the start but soon closed up on the field in last of the four runners.

Whatsallthatabout was first to come under pressure after the halfway stage as Emperor Of The Sun still dictated.

The latter was asked for more by Donnacha O'Brien passing the two pole and the pair were two lengths clear of Delta Dawn hitting the furlong marker.

Delta Dawn (5/2) stayed on nicely in the last 100 yards, though, to close to within three parts of a length at the line.

Dermot Weld 's Gatwick Kitten will have gone into plenty of notebooks in third, on debut, a further two lengths off the Ballydoyle pair.

Donnacha O'Brien said: "He did it nicely. He had a good run the last day (in third at Killarney). He is still quite green, quite raw. Plenty to learn still but he has ability.

"He is still raw and gawky. In an ideal world you'd like to get a lead on him but if I had done that he'd have gone too slow for his own good so I had to make the running on him.

"He stuck at it well and he'll learn plenty from it.

"The second horse (Delta Dawn) had a decent run the first day and would have learned a lot from that as well and I'm sure they are smart horses."
