Fanatic settled back of midfield on the fence before rider Mark Hills got her off the rail with 700 metres to run. They made rapid ground to be in contention on straightening and dashed clear 200 metres from home for an emphatic win.
"As long as she pulls up well, she'll go to the City of Auckland Cup on New Year's Day," Sweeney said.
Fanatic is also nominated for the group three Wallaceville Estate Wellington Cup and the group one Auckland Cup with the latter feature at Ellerslie her more likely target.
The stable and Hills had earlier celebrated a victory from their $1 million group one Vodafone New Zealand Derby hope Wehadadeal in thebestlittlebookstoreco.nz 1400.
"It was a good effort and we thought he would go close," Sweeney said. "He was left a sitting duck the other day. He's a nice, relaxed horse with a lovely attitude."
Wehadadeal had placed at his first two appearances before his last-start fifth at Waipukurau.
