Waddell took the initiative to go forward but was trapped three-wide before looming into contention five-deep on the home corner.
Tackled by Rendition and then Tibetan, Scorpz fought back bravely to win by a neck at the line, much to the relief of Waddell who admitted the ride wasn't text-book. "It was far from pretty but it was effective," Waddell said.
"The speed came out of the race and I was sitting back second last and thought if I stay back here it's just going to be too hard for him.
"I pulled out three wide with no cover and just let him move. I let Leith (Innes, aboard Rendition) go past me on purpose just so he could fight back and he kicked back strongly.
"I don't think there is any worry about him getting the Derby distance as he pretty much went that today."
Waddell was referring to the Gr.1 Vodafone Derby (2400m) on February 29, a target that Marsh has firmly in his sights for his charge.
"We will work back from the Derby now as he has had his run over ground, we've been to Ellerslie and we can do basically what we like now," Marsh said.
