Rock Street made the most of the opportunity handed to him by the luckless Killenaule Boy to land the Lisronagh (C & G) Beginners Chase in testing conditions at Clonmel.
Robert Tyner's seven-year-old (3-1) turned into the straight alongside the favourite and the pair had the race between them as there was a long gap to the rest.
Killenaule Boy looked to be getting the better of the duel until he hit the last hard and lost all momentum, allowing Rock Street to grab the spoils by four lengths under Philip Enright.
It was a fifth consecutive second-placing for Killenaule Boy and a sixth over fences in all.
