Bay Knight came with a storming late run to claim the six-furlong handicap at Dundalk under Keagan Latham.
The Willie McCreery-trained colt got up close home to score by three-parts-of-a-length from Copper Dock
"I thought he gave him a super ride. He had a desperate draw and I told him to miss the kick and see how he was travelling in the straight," said McCreery.
"He said he travelled great and picked up well. He's an improving horse and is only a three-year-old.
"He won at Kempton last time and here tonight so you can't complain about him."
