The owners of Manhattan Blues will pay a late entry for the Blue Diamond Stakes giving trainer Tony McEvoy two chances in the Group One race.

Manhattan Blues' last-start second to stablemate Stoker, a $15 Blue Diamond chance, convinced his owners to pay the $55,000 to put him in Melbourne's premier two-year-old race at Caulfield on Saturday.

Stoker's winning prize money from the sales restricted Inglis Premier (1000m) at Sandown on February 7 counts towards his inclusion in the field but the $45,000 Manhattan Blues collected does not.

He sits just outside the final field while Stoker is fourth on the order of entry and McEvoy is relying on some of the higher qualified horses being non-acceptors.

Damien Oliver rides Stoker while the trainer has booked Nick Hall for Manhattan Blues but the jockey must pass a medical examination on Wednesday when he has stitches removed from his leg after a trackwork accident.

Stewards placed a warning on Stoker over his behaviour before his Sandown win but McEvoy said he had been like a lamb since returning to Angaston in South Australia.

"His blood picture's perfect, he's eating well, he's working well, so he just had a bee in his bonnet the other day," McEvoy said.

"I'll probably have two people in the paddock with him this time and I'll get him ponied around to the start.

"It did concern me on the day and they gave him a warning but I've had him back to the barriers since and he's been fine."

Stoker finished second on debut at Moonee Valley in December behind Headwater who assumed favouritism for the Golden Slipper with his win in Saturday's Silver Slipper at Rosehill.

A debut winner at Morphettville, Manhattan Blues ran sixth in the Blue Diamond Preview won by Burnstone before his second to Stoker.

"He's worked well and done everything right and I will be paying up for him," McEvoy said.
