As a young horse Werther was less impressive looking than most of the Tavistocks, but Campbell wasn't put off.
"There was something about him when you saw him in a paddock with other horses," said Campbell in the Ellerslie birdcage after a win before Werther went to Australia and was then on-sold to Hong Kong.
If Werther improves from this point he will be a world sensation.
Meanwhile, you've got to hand it to the durability of St Emilion winning at Ellerslie on Saturday.
He was backing up for his third weekend straight and lumped his 60kg topweight like a real trouper in front to hold on by a breath.
"He can go out for a spell now," said co-trainer Andrew Forsman. "He's won nine races now, all of them in significantly less than 12 months."
