Ruby Walsh won on Un Beau Roman at Downpatrick but was denied an expected double when pulling up Mr Groocock three flights from home.
The Willie Mullins-trained Un Beau Roman was an easy winner of the Sunday Hospitality Hurdle, scoring by 24 lengths with success secured long before the final flight having made all the running.
The complexion of the Sunday Fun Club Maiden Hurdle changed abruptly when Walsh pulled up Mr Groocock three flights from home having been at the head of affairs for most of the race.
Little King Robin, under Mark Walsh, claimed the race with the mare having registered her sole previous success at the nearby Tyrella point to point venue.
Winning trainer Colin Bowe said: "She was due that one – a novice handicap hurdle would be a possibility next time."
Sea Rocket, trained by Christy Roche, proved the facile 17 length winner of the Lazy Sunday Mares Maiden Hurdle.
Partnered by stable jockey Alan Crowe, Sea Rocket – supported from 9/1 in the morning to 11/4 on course – won the first race in good style, leading prior to the last.
Crowe said: "She's small but tough. The course management has done a great job with watering of the track."
Favourite Over Church Road – trained in Downpatrick by Brian Hamilton – finished fourth but the Turf Club advised the mare was found to be lame post race.
