Monday's $30,000 Lexus Of Parramatta Canola Cup Final (2100m) at Eugowra, the richest C1 event in Australia brought together a top field of pacers, and provided the combination of Steve and Amanda Turnbull with yet another feature race win.

Former Kiwi gelding Oh I Am The One, which opened as a $1.85 favourite with TAB Fixed Odds but drifted to start at $2.60, proved too classy for his rivals, running them ragged with an all-the-way win in a track record mile rate of 1:57.0.

"Once he held the front I knew he would be pretty hard to beat," Amanda Turnbull said after the race.

"Dad and 'Whitey' (owner Craig White) got him from New Zealand through our agent Stuart Valentine, who does a really good job with finding these good horses, and we thought he'd be hard to beat in this series.

"The biggest query was whether he would hold the front because he had lacked speed in New Zealand, and even when I sprinted him up in the warm-up he was a casual bugger and didn't feel that quick, but once he was able to hold them out and lead and I was able to get him to settle and have that cheap early quarter he was the one to beat.

"We've been coming here most years trying to win it without luck and it takes a good horse to win it, so I'd say Dad will have a bit of fun with him."

Despite those queries about his gate speed, Oh I Am The One was able to hold out his rivals in the early stages and maintain top spot.

Back in the field Go Lassie Go (Murray Sullivan) went into a gallop, inconveniencing Francisco De Gore (Corey Bell) and breaking the field up to the point where there was only six legitimate chances left by the halfway point of the race.

After the early burn, Turnbull was able to take a breather on Oh I Am The One, running the first quarter of the last mile in a leisurely 31.1s.

But after getting a cheap sectional she poured on the pressure, making her main rivals Lucy Lamb (Mat Rue) and Tullow (Brad Hewitt) work from the death seat and one out, two back trail respectively.

Middle splits of 28.9s and 28.1s saw the Gotta Go Cullen (NZ) x Angel Hanover (NZ) gelding put a big gap between him and his rivals, and with the final 400m being run in 29.0s nothing else was given a chance.

On the line Oh I Am The One had 27.5m to spare from Tullow, with Swaggie Shannon (Emma Turnbull) gaining an inside run to finish third.

The well-supported Lucy Lamb dropped out after working hard outside the leader, eventually finishing 94.7m away from the winner in seventh place.

"It's hard to come from behind here at Eugowra so I wanted to try and bust them up the back of the track each time and get them chasing," Turnbull said.

"Coming down the straight I couldn't hear the other horses so once we'd passed the line I looked around and couldn't believe how far we had won by."
