Lord Snow has been a work in progress and he's now ready to get back into action after a lengthy break.

The son of Postponed will make his first appearance for 10 months when he steps out in the Elm Street Development 1400 at Avondale on Friday.

"He's ready to go again and he's been taken along quietly – he's a very big horse so he's needed some time," said Moira Murdoch, who trains the Postponed gelding with her daughter Kieran.

Lord Snow was a debut second on the course last year before he broke his maiden next time out at Te Rapa and another second followed before he was turned out. He recently finished fourth in an open trial to ready him for his return.

"He's got a bit of weight (60kg) so it remains to be seen how he copes with that," Murdoch said.

"He will be better once he gets to a mile, but he is forward enough to run a cheeky race."

The stable is also looking forward to the return of the promising mare Sacred Siren in Saturday's Balance Agri-Nutrients 1400 at Te Rapa.

"She's trialled up nicely and she's quite a light type of mare so we don't need to do too much with her," Murdoch said.

Sacred Siren has won twice from seven appearances and the O'Reilly mare, a daughter of the Listed NZ St Leger runner-up Striptease, will be having her first start since December.
