Kevin Prendergast ruled out any notion of Beach Belle travelling to Newmarket next month to compete in the Dubai Fillies' Mile.
The County Kildare handler has yet to be convinced about the filly's levels of stamina after she finished well down the field in the Moyglare Stakes at the Curragh on Sunday.
Beach Belle is now likely to be pitched into a weaker race instead of running in the Newmarket Group One on October 17.
Prendergast said: "We were disappointed with her and, looking at the weekend, you'd say she didn't get seven (furlongs).
"They didn't go a good pace, either, but I think she'll be back. She's too good a filly not to come back.
"I don't think that (Fillies' Mile) is an option now.
"We'll lower her sights a bit and try to get her back on a winning track."
Another Prendergast filly, Tamadhor, is poised for a step up in class at the Curragh towards the end of the month following her convincing victory on Irish Champions Weekend.
She looked impressive in a seven-furlong maiden at Leopardstown on Saturday when she accounted for Stellar Glow by half a length.
Sheikh Hamdan Al Maktoum's youngster is now in contention for the Group Three CL Weld Park Stakes on September 28.
Prendergast said: "She ran really well and is a very nice filly.
"We were very happy with her because she had a bad draw but still quickened up really well.
"The idea now is to think about the Curragh race and then see where we are. I'm quite keen to see her run again this autumn."
