Barshiba will face 11 rivals as she bids for back-to-back victories in Saturday's bet365 Lancashire Oaks at Haydock.
David Elsworth's runner was a near four-length winner of the Group Two heat under Paul Hanagan, but the six-year-old is set to be partnered by Hayley Turner this time after the duo struck gold at Ascot earlier in the season.
Les Fazzani, Polly's Mark and Rosika filled the first three places in the Pinnacle Stakes at this track last month, with Barshiba in fourth. They all line up again along with Henry Cecil's Flame Of Gibraltar (fifth) and Cassique Lady (seventh).
The latter, who is trained by Lucy Wadham, subsequently finished second behind Lady Jane Digby in the Warwickshire Oaks and she will clash with that rival again.
Lady Jane Digby was compensated for a luckless run in the 2009 renewal of the Warwick Listed heat when claiming that prize, but she was then edged into second at Newcastle.
Trainer Mark Johnston said: "We were pleased to win at Warwick but obviously she was beaten into second at Newcastle last week. She's a tough cookie, though, and this looks a good opportunity for her."
Barry Hills' Oaks 10th Champagnelifestyle drops back in company and she is one of two three-year-old runners, along with Clive Brittain's Najam. Dermot Weld's Noblesse Stakes winner Grace O'Malley, Gerard Butler's Tinaar and the Roger Charlton-trained Clowance complete the field.
