"I knew he would be fit enough but he's 9 years old and hasn't won a flat race for quite a while so that was a big question mark before the race," he says.
"Looking at the field, they were mainly jumpers so I thought if he could revert to his best flat form he was a big show, but it was just whether he could actually do that. To be quite honest I wasn't sure just how he would go but he was good enough to win a Summer Cup earlier on in his career before he got injured. He was off the scene for ages after he hurt a tendon when he won that race, and he did have good form around that time.
"We put him out for a spell then got him in and worked him up before we put him out again. Touch wood, he has been okay since he came back about a year ago but he hadn't won a race until today."
Master Fin is owned and bred by Awapuni identity Graeme Martin, who Oulaghan believes will be keen to see his charge make the trip to Australia to contest the Jericho Cup.
"He probably fits the bill for the race in Australia but I will have to speak to Graeme about that," Oulaghan said.
"I would think he will be keen but we will just have to see how things pan out before any final decisions are made."
This year there are two special qualifying events run in New Zealand that provide guaranteed entry into the Jericho Cup, with the second being raced at Riccarton on Saturday, October 24. The 2020 Jericho Cup will be run at Warrnambool on November 29.
