Four juvenile heats at the Randwick trials on Tuesday morning produced an impressive winner for the James Harron Bloodstock team in royally named colt King.

Bought for $1million by JHB at the Inglis Australian Easter Yearling Sale from the Turangga Farm draft, Written Tycoon colt King looked a different horse on Tuesday with the addition of blinkers.

The Peter and Paul Snowden trained colt was given a very quiet trial behind subsequent winner Legend of Condor on October 3 and was allowed to drop out over the last furlong to finish a distant ninth of 10.

This time around, King was asked to be a racehorse by Tim Clark and responded as you would hope for.

He jumped well from an outside gate and powered forward to take up the lead, zooming clear to win under a hold by three lengths. He clocked 43 seconds dead for the 745 metre trial, which was more than a second quicker than the other juvenile heats and faster than all the older horses as well.

The most expensive yearling ever sired by Written Tycoon, King is the first foal of stakes-winning juvenile Brilliant Bisc, a daughter pf Group I winner Stella Cadente from the family of Golden Slipper winner Bint Marscay.

Brilliant Bisc was the top priced offering at the Turangga Farm Dispersal earlier this year when fetching $600,000 to the bid of Go Bloodstock.

Other 2yo trial winners were Old Harbour (Your Song), Sakura (Sepoy) and Elessedil (Exceed and Excel).
