Johnston pair supplemented for Derby As expected the Mark Johnston-trained pair of Bandari and Fight Your Corner have been supplemented for next Saturday`s Vodafone Derby at Epsom.The pair, who have both been sold to Hamdan Al Maktoum and Sheikh Mohammed`s son Sheikh Hamdan respectively in recent weeks, have been added to the field for the premier classic after impressing in their Derby trials.Bandari blew away a fair field in the Lingfield Derby Trial, seeing off his rivals by an easy 13 lengths while Fight Your Corner staked his claim by taking the Chester Vase at the May meeting.The two colts were not entered at any of the previous stages and the owners have had to pay #90,000 for their horses to takes part.Bandari is set to be partnered by retained rider Richard Hills with Kevin Darley likely to keep the mount on Fight Your Corner.Bandari and Fight Your Corner were the only two additions to the field for the one and a half mile classic.
