Mosspark (9/2) took the scalp of Carraig Mor in the Stanjames.com Sidney Banks Memorial Novices' Hurdle at Huntingdon on Thursday.
Just five went to post for the Listed race, and Emma Lavelle's six-year-old was to maintain his unbeaten run this term with a fine display under Aidan Coleman.
The winner traded the early fractions with outsider, Chase The Spud, and four of the five runners could be considered to hold chances as the race began in earnest with four flights to take.
Well-backed favourite, Carraig Mor (4/6), was asked to take closer order by Robert Thornton, but his moment of glory at the head of affairs was to be shortlived as the son of Flemensfirth rallied and ultimately saw out of the trip with very few moments of concern for his backers.
Top-weight Spirit Of Shankly ran on to be second, despite making a couple of mistakes, while the favourite finished a laboured third having found disappointingly little for pressure.
Lavelle's partner Barry Fenton told Racing UK: "The ground, trip and track were probably against him today we thought.
"He was very impressive at Exeter first time, then at Leicester it was a complete bog and we were in two minds about it, but with nice horses you think they are invincible.
"He ran but was never happy and just pure ability brought him through.
"We gave him three weeks in a field and then slowly brought him back with the view the weather must change but it hasn't.
"He has an entry for Cheltenham (Albert Bartlett) and we were stuck between a rock and a hard place because he needed to run if we have any thought of going there.
"I'm still not saying he's going but if he hadn't run today, then we definitely couldn't go. He was impressive.
"Emma will discuss plans with the owners - for me he's a future RSA horse."
