On His Own put Roi De Mee firmly in his place with an easy victory in the Imperial Call Chase at Cork.
The duo fought out the Grade Two contest over three miles from a long way out, but Willie Mullins' 2014 Cheltenham Gold Cup runner-up had too much class for his in-form rival and steadily pulled clear through the closing stages.
On His Own (9-10 favourite) gained the upper hand two fences from home under the supervision of David Casey and was not hard-pressed to account for Roi De Mee by 15 lengths, with the runner-up only just holding on for second from Letter Of Credit.
Casey, whose mount finished a creditable fifth to Coneygree when he tackled the Gold Cup again last month, said: "He was well-in at the weights and seemed in good enough form.
"This was a much lower Graded race than the Gold Cup, but after Cheltenham you never know how they are until you run them.
"He jumped well in front and age isn't catching up with him yet.
"He might be one for the Grand Steeple-Chase de Paris, but I don't know what Willie might have in his head."
Eamonn Corbett sustained a suspected broken leg after he suffered a first-flight fall from Snaidhm in the Corkman Mares Maiden Hurdle, which was won by 4-1 chance Emcon.
