Third on his sole point-to-point start when trained by Sean Doyle, the bay five-year-old was again third on his racecourse debut at Downpatrick earlier this month.
In a share of the lead early on, the son of Malinas got to the front after the second. He was strongly pressed and joined from two out, but kept finding for pressure and was in-front again on the run-in, going on to score by half-a-length.
Noble Birth (10/3) was a luckless second under Jack Kennedy. Caught for room on the inner approaching the last, he got the desired gap inside the final 150 yards and while he came home well, he couldn't reel-in the winner.
"He's tough and he stays. He'd a lovely run in Downpatrick the last day and it's great to get him off the mark today," Blackmore said.
"He was a bit lairy in front and he's a stayer so, in hindsight, maybe I could have gone a stride quicker in the middle part of the race but he did it well in the end."
