Owner-breeder Bob Peters has made no plans past Saturday's $200,000 Champion Fillies Stakes (1600m) with his impressive Burgess Queen Stakes winner Antique Belle.
Peters has the option to back up Antique Belle in the $350,000 WA Guineas (1600m) and try to follow in the footsteps of her close relation Kalatiara, who won the Burgess Queen-WA Guineas double in 2000.
Only two other fillies, Moccasin Bend (2008) and Clueless Angel (2009), have been successful in the Guineas since.
"She is a fragile filly and I don't know whether she would take backing up," Peters said.
"She is just not a robust filly and we need to look after her a bit."
Player was so impressed by the authority of Antique Belle's 2 1/4 - length win in the Champion Fillies' lead-up she was elevated to second favouritism at $4.20 behind last season's Karrakatta Plate-WA Sires' Produce Stakes champion Luke's Luck ($3.20).
The Champion Fillies had been a hoodoo race for the Peters family for close to 40 years, until Dreamaway won in 2011.
"I won the Sheila Gwynne Stakes, which was the major lead-up to the Champion Fillies, five or six times," Peters said.
"For some time I couldn't work out what kept going wrong. Then it dawned on me it was the set weights of the Champion Fillies.
"Our fillies had gone into the Sheila Gwynne at the bottom of the handicap, but when they came into the Champion Fillies they met the topweights (of the Sheila Gwynne) on equal terms. The shift in weights had a lot to do with it."
Antique Belle, who was penalised 13 points for her Burgess Queen win, has drawn gate three.
The Redoute's Choice three-year-old meets Darlington Abbey on level weights on 55.5kg, after carrying a 4kg advantage to beat last season's star two-year-old by 2 3/4 lengths, when she finished third in the Burgess Queen.
Darlington Abbey's stablemate Miss Solis, who ran fifth (3 1/2 lengths) in the Burgess Queen, meets Antique Belle 3kg better.
