Ross will have only one runner at Doomben on Wednesday when he saddles up The Missionary in the QTIS Three-Year-Old Handicap.
The Missionary has won two of her past four starts.
But, she is coming off an average run last start when she tailed off in a field of nine behind Prince Shalaa over 1350 metres at Doomben on September 10.
“She was a bit disappointing last start and we thought maybe she’s had enough,” Ross said.
"But, she’s worked well since and looks good.
“She won two in a row at the Sunshine Coast then ran second at Doomben before she ran last at her last start.
“If she runs up to her best form, she’ll be hard to beat.”
Ross has booked jockey Tiffany Brooker to partner The Missionary, replacing last start rider Samantha Collett.
Brooker rode the daughter of The Mission in her three previous starts for two wins and a second.
