The Campbell Watt-trained youngster had put together a string of minor placings, five in fact, from his previous seven starts.
Being a prolific placegetter runs in the family as his now retired half-sister Vicki's Ticket that retired a maiden but had 12 minor placings from her 48 starts.
With a win under his belt, Watt will proceed with plans to enter the gelding in the upcoming Dandy Patch series (Tasmanian sires stakes for colts and geldings) later this month.
"He's a consistent little horse and he deserves his chance in a big race," Watt said.
Blackjackhanover was bred by Watt from his former handy race mare Ticketoride that won on debut but had to be retired after 12 starts due to heart strain.
"Blackjackhanover (x Cardmaster Hanover) is her fourth foal but the first to win," he said.
Blackjackhanover's win at $5.70 came courtesy of a heady drive from Nat Emery who rated him well, got away with a pedestrian second quarter to ensure the gelding had enough in reserve to stave off a late and determined challenge from odds-on favourite ($1.20).
