Sublimity made the most of a significant drop in class as he got back to winning ways with a workmanlike victory in the McCarthy Insurance Group Hurdle at Cork.
Winner of the Champion Hurdle in 2007 but successful only once since, the Robbie Hennessy-trained 11-year-old travelled with his old dash at the rear of the four-runner field as Newmill opened up a huge early advantage.
Ridden for the first time by Andrew Lynch and massively favoured by race conditions, he had closed the gap going to the third-last but 2006 Champion Chase winner Newmill proved game in front and the pair were upsides jumping the last.
Sublimity had to fight from there but just had the extra edge in speed on the run to the line, prevailing by half a length as the 11-10 favourite.
Hennessy was delighted to see Sublimity get his head in front again and said: "Today was one of my best successes despite having won a Grade One.
"It's nearly as good as winning at Cheltenham as he had a bad suspensory injury last year and we weren't sure if he would run again.
"It's great to get that out of the way. Beforehand on all ratings he had to be nearly a good thing, but there is no such thing in racing.
"These type of races are his future. There is a race at Naas in a few weeks for him (Limestone Lad Hurdle) although it's over two miles, three.
"The Irish Champion Hurdle is also a possibility."
Should Sublimity run in the Limestone Lad there is a strong possibility he will clash with Dunguib.
