Trainer Brad Widdup will be out to continue his good run of form at Rosehill.

A week after celebrating a metropolitan double at Randwick, trainer Brad Widdup will bid to keep his momentum rolling by chasing a consolation win with filly Mum's The Boss at Rosehill. 

Widdup originally had designs on a Queensland Oaks start for the Foxwedge three-year-old but when she was going to struggle to make the field, he diverted back to Saturday's The Agency Handicap (1800m). 

Rachel King will ride her and Widdup is anticipating an improved performance on her last two starts. 

After posting a second-up win over 1600m at Kembla Grange, Mum's The Boss finished tenth to Dynasties in the Gold Coast Bracelet (1800m) then midfield behind another Queensland Oaks hopeful in Aravene over 2000m at Rosehill. 

"Her last two runs have been better than they have looked," Widdup said. 

"She was slow away in the race at the Gold Coast and got too far back. 

"The other day in town, they all came around her just before the bend and she had no hope. 

"She is on track, but she just needs a bit of luck." 

Widdup's luck took a turn for the better last weekend when promising filly Moon Reader and consistent sprinter Surreal Step broke through for city victories. 

Mum's The Boss is an $7.50 chance to add to the trainer's tally, with the Annabel Neasham-trained African Daisy a $3.40 favourite to land her second win at start number six.
