JOHN Dunlop introduced a pair of Classic contenders as he took both the main events on Lingfield's trials card.

The Sussex trainer, who knows exactly what it takes to win the Derby and the Oaks, turned over the favourites in both the Letheby & Christopher Derby Trial and totesport.com Oaks Trial with Kong and Cassydora.

Kong will bid to follow a path last trodden by High-Rise in 1998 after showing plenty of resolution to take the colts' event.

The Luca Cumani-trained High-Rise was the last winner of this race to go on to take the big one at Epsom the following month.

But Dunlop himself had gone remarkably close 12 months earlier when Silver Patriarch found only Benny The Dip a short head too good in the world's most famous race after warming up with success here.

The Richard Quinn-ridden winner booked his place in the June 4 line-up as he held off the challenge of favourite Walk In The Park.

And although Kong's performance hardly left bookmakers in raptures, he handled the course well and did enough to satisfy connections that he will not be disgraced at Epsom.

Melrose Avenue set a steady gallop that patently did not suit the hard-pulling market leader or Kong, so Quinn opted to send his mount to the front well over two furlongs out to try to take the sting out of his rivals.

Walk In The Park picked up the pace to throw down a challenge but he was unable to get to the 9-2 winner, who held on to take the Group Three prize by a neck.

"He did everything right and if he stays sound and happy then we'll go to Epsom,'' said Dunlop.

''He has always been a very good-looking horse and a lovely mover. He's a brother to a lovely filly called Preseli who won the Moyglare Stud Stakes.

''I was a bit apprehensive about the ground for him as a son of Sadler's Wells. Lingfield missed all the rain and that was a worry, but he seemed to handle it well.''

Coral slashed Kong's odds for the Derby to just 14-1, but Ladbrokes took a more realistic view at 25-1.
