Triple Group One winner Nature Strip has cruised to a barrier trial win at Warwick Farm as he ramps up preparations for his return.
Nature Strip easily led Tuesday's 900m-heat on the course proper and went to the line hard-held under James McDonald.
White Moss was second throughout and just maintained that position from Yes Yes Yes who worked home strongly.
Trainer Chris Waller has Royal Ascot ambitions for both Nature Strip and Everest winner Yes Yes Yes.
Nature Strip is slated to resume in next month's Group One Lightning Stakes at Flemington while three-year-old Yes Yes Yes may begin his campaign in Sydney.
