Sky Sports Racing ambassador Hollie Doyle previews a busy weekend of Flat racing, focusing on her mounts' chances in key contests. Docklands is her main target in the William Hill Doncaster Mile Stakes (2.57), a Listed race where the son of Zafonic aims to stamp his class. Doyle believes the big, galloping gelding, who bypassed Dubai, is far too good for his four opponents. Kamakay, a filly trained by Eve Johnson Houghton, gets a handicap debut at Southwell (5.30) after a strong showing in novice company. Aura Champagne, Richard Hannon's filly, returns to action at York (6.30) after an encouraging third at Newbury. Doyle also rides Golden Muse, Marco Botti's Golden Horn filly, in the Midnite A Fillies' Novice Stakes (7.00), hoping the longer trip suits after a promising Wolverhampton win. Kings College, a big horse trained by Richard Newland and Jamie Insole, is expected to thrive at the more galloping Southwell (8.00), moving up from a sharp Wolverhampton run. Teggy Lasso, Ivan Furtado's gelding, seeks redemption over a shorter trip at Doncaster (8.30), returning to a mile after a tough 10f at Newcastle.
