Four of the runners in Melbourne’s premier juvenile race will require further testing before being passed fit to start at Caulfield.

Racing Victoria vets inspected all 16 two-year-olds on Thursday ahead of Saturday’s Group 1 Blue Diamond Stakes (1200m) at Caulfield.

Lofty Strike and Kiki Express both presented with lameness. Lofty Strike in the off-foreleg and Kiki Express in her nearside foreleg.

The well-supported Sebonack had swelling in his right fetlock earlier on Thursday, but Hawkes Racing has since presented a satisfactory ultrasound and x-ray report.

Sebonack will be re-examined as a precaution.

The Peter Moody-trained Rampant Lion shifted a shoe on his near fore on Wednesday night before being reshod on Thursday morning and the colt will also undergo a re-inspection on Friday.

The Mick Price and Michael Kent Jnr-trained Jacquinot remains favourite with TAB at $5 ahead of the Peter and Paul Snowden-trained Revolutionary Miss at $6.

Sebonack sits alone on the third line at $7 with Lofty Strike, the one-time second favourite, drifting to the fourth line at $7.50.

Rampant Lion is a $19 chance with Kiki Express an outsider at $34.
