Antartica can come in from the cold to win more black type

Lambourn: James Burn

Passing Call 12.25 Doncaster, nap
Yet to win in five starts, but has not been disgraced and posted some useful form, while this looks a perfect slot for her to get off the mark.

Others to follow
Doncaster 2.05 Don't Ask, 2.40 Got Away.
Southwell 12.45 A Few Good Men, 1.15 Beyond Recall.

West Country: Tim Mitchell

Antartica De Thaix 2.40 Doncaster, nap
Three-time winner over fences last season including a Listed contest and would have derived plenty for reappearance when chasing home Mia's Storm. Fancied to add some more black type to her CV.

Others to follow
Doncaster 12.55 Tomorrow Mystery, 1.30 Copain De Classe, 3.40 Gingili.

North: Colin Russell

Brother Tiger 2.25 Southwell, nap
Not at his best when last seen out, but on a good mark at present and, having run well on his only previous start on the course, is fancied to fare much better this time.

Others to follow
Doncaster 12.25 Canny Style, 12.55 Shine Baby Shine, 1.30 Robbing The Prey, 2.05 High Jinx, 3.10 Another Bill, 3.40 Ganbei.

Racing Post Ratings: Steve Mason

Black Op 2.05 Doncaster, nap
Beat the classy Claimantakinforgan in a bumper here and shaped like a certain future winner when finishing a good fourth in a hot Newbury maiden on his recent hurdles debut.

Topspeed: Dave Edwards

Satchville Flyer 3.00 Southwell
Yet to win on Fibresand, but has been knocking at the door recently and David Evans' six-year-old would not be winning out of turn.

Longshot: Ed Quigley

Bon Papa 1.55 Leopardstown
Quirky sort, but stacks of ability as he showed on his chase debut and shapes as though he should excel at this trip.

Ireland: Tony O'Hehir

Daly Tiger 3.35 Leopardstown
The Noel Meade-trained four-year-old won his bumper easily at Thurles before finishing second to the useful Real Steel in a maiden hurdle at that same track. A second bumper win looks on the cards for Nina Carberry's mount.
