Soph should prove a class above her rivals in the Oamaru Cup at Oamaru tomorrow.
She is among several top prospects for the Wanganui stable of Kevin Myers.
Keep It Tight, Macsmallpee, Il Poverino, Irish Charmer, Krase, Caley Marie and Yanna Marie are other members of the stable engaged.
Soph, the top weight with 58kg for the 2200m race, has won open middle distance handicaps at Otaki (Raukawa Cup), Hastings (a premier 2200m last October) and New Plymouth.
She was runner up to Bruce Almighty in the Canterbury Gold Cup and Marlborough Cup and second in the Feilding Cup last season.
The Lord Ballina mare finished close up in two races for mares in Melbourne in June and fourth in the Whyte Handicap (1600m) at Trentham at her last start.
Yanna Marie is top weight for the open 1400m but her rider Zman Zulkifli can claim 2kg.
She has not raced since finishing fourth in the Wanganui Stakes (wfa 1600m) on June 5.
She had won over 1400m at Trentham and Waterlea in her two previous starts.
Yanna Marie is among 19 horses remaining in the $100,000 Winter Cup at Riccarton next Saturday after first withdrawals.
The final field will be 18.
Yanna Marie ran sixth in the Winter Cup 12 months ago and fourth in the Winter Classic at the Grand National meeting.
Don't Say Clang, Royal Flight, Aussieaussieaussie, Faaltless and Kirkdouglas are other Winter Cup aspirants opposing Yanna Marie tomorrow.
Royal Flight is unbeaten in two starts at Oamaru, both over 1400m.
She resumed after a three-month break from racing with a third to Romany and Arctic Ace over 1400m at Ashburton on July 11.
Arctic Ace is backing up today after finishing a close third to Eel Win and Romany over 1200m at Oamaru on Wednesday.
