After the first quarter Christen Me was in a small bunch of stragglers four lengths off the leading group.
"I ended up quite a way further back than I wanted to be on my first quarter and I sort of made my move to give him a bit of a breather," said Dexter Dunn, stable driver for West Melton trainer Cran Dalgety.
"That's the value of a horse like him, he just does pace so easily."
The $150,000 Copthorne Commodore 2YO Emerald was won by Clevedon trainer Barry Purdon's Sky Major, who also overcame a bad draw and some traffic problems to win in yet another record time, 1m 52.9s, beating stablemate Maxim.
The win was the only one of the day for part-owner Christchurch restaurateur Trevor Casey who had a remarkable eight runners on harness racing's championship day.
In the female pacing Jewels races, Venus Serena had to dig deep to win the $150,000 Ashburton Guardian 2YO Diamond after Mark Purdon's filly Te Amo Bromac took the lead inside the final furlong.
"She got past me at the 150 but to this thing's credit [she] came back and got her on the line so a great effort by her," said driver John Dunn, who drove for uncle Geoff Dunn, the West Melton-based trainer.
Champion filly Adore Me won the $150,00 Mid Canterbury Trotting Owners 3YO Diamond for Mark Purdon.
