Sussex and Wayne Lordan beat Comfort Zone © Photo Healy Racing
Only tenth on both of his previous starts, 12/1 chance Sussex left that form well behind when taking the Irish EBF Supporting TREO EILE Maiden.
The Dubawi colt was out smartly from stall one and led turning out of the back straight.
Pursued by the 4/5 favourite Comfort Zone all the way down the straight, the winner kept finding enough under Wayne Lordan to see off the marker leader by three quarters of a length.
Debutant Navajo Warrior (6/1) finished a further two lengths away to make it a one-three for winning trainer Aidan O’Brien.
Out of Listed winner Kiss who is a three-parts sister to Derby winner Pour Moi, Sussex holds an entry in Saturday’s Group 3 Eyrefield Stakes at Leopardstown.
“He's obviously after improving from each run. I had a good draw today and was able to dictate it and he stuck at it well,” said Lordan.
“He handles the ground and he's tough. Hopefully he'll keep stepping forward now.”
