Dunn also considered Lubrication a future stallion prospect as a younger horse before he was forced to geld the son of Invincible.
“He looked like being a really nice horse in his early days, but he hasn’t quite lived up to it,” Dunn said.
“He’s still eligible for Class Three but he’s got a rating of a Class Five horse that’s why we aim him for Plate races.
“This is a nice race for him and with his good gate (barrier 2) he’ll be hard to beat.”
Although hopeful Lubrication can notch up win number four at his 14th start, Dunn has no plans to send him to Sydney for the spring.
Dunn won yet another Highway Handicap at Randwick on Saturday with Cranky Harry and continued his fine form with a winning double from six runners at Grafton on Sunday.
In-form sprinter Denied looks the main threat with a three-kilogram claim for Emily Lang, who was aboard the four-year-old mare when second to Atlantic Ocean in a 1350-metre Benchmark race at Doomben last month.
Denied was chasing his fourth straight win for Bruce after notching up wins at the Sunshine Coast and Doomben.
