Doctor Steinberg maintained his perfect record over hurdles with a comprehensive victory in the Nathaniel Lacy & Partners Solicitors Novice Hurdle at Leopardstown.
Hot on the heels of wins at Galway and Navan, where he accounted for subsequent Grade Two winner Thedeviluno, the Willie Mullins-trained Doctor Dino gelding again demonstrated his liking for obstacles when galloping home eight lengths clear in the hands of Paul Townend.
Yeshil made the early running, but the 7-4 favourite took up the running two out and quickly put the race to bed, with Kazansky staying on for second.
