He had expected to press forward from his outside draw and try to get in front of favoured rivals Habibti and Stig but that plan soon went out the window as Sovereignty and The Fiery Ginga rushed off the gate to lead and trail.
That saw Stent settle last and when Stig trotted up to sit parked with Habibti on his back in the one-one position, De Filippi had a lot of work to do.
But last season's Anzac Cup winner trotted into the race powerfully down the back straight and forced Habibti into a pocket, from where she galloped at the 300m mark.
That left Stent to cruise clear for a 1-length win in a steady 1:57.8 for the mile.
It was only his second win of the season and suggested once again, at this still relatively early stage of his career, he is most potent over shorter trips than the 3200m of the Dominion or Rowe Cup.
He now heads to next Tuesday's $80,000 National Trot at Alexandra Park before the De Filippis need to decide whether to chase the mega rich Australian double of the Glenferrie Farms Challenge and Great Southern Star in March. While the winner left his rivals with few excuses, the connections of local hero Sovereignty will be relieved with his vastly improved second.
He had lost all form during his most recent South Island campaign but showed how much he loves being home by blasting off the gate and trailing before punching home hard up the passing lane.
However, veteran Stig suggested his days of winning mile races, particularly on 1000m tracks, may be over as he was flat out keeping up parked so he is probably better staying in New Zealand than tackling the autumn Aussie features, which are over the shorter trips.
Meanwhile, the Auckland Trotting Club will honour recently retired champion trotter I Can Doosit at their premier meeting on Tuesday.
The $1.45 million earner will lead out the field for one of the trotting races before being presented with a special dress rug celebrating his career.
