Tamarisk, the top-rated European sprinter of 1998, will have his comeback race in the US65,000 John Henry Stakes over an extended mile at Arlington Park, Chicago tomorrow.
The horse was sent back into training after his brief stud career was ended by fertility problems.
Chris Emigh will ride the five-year-old in the 12-runner field for owner Highland Farm and trainer Elliott Walden, who hopes to transform the horse into a miler on grass.
As a two-year-old, Tamarisk won three of his four starts and finished second to the outstanding European juvenile Xaar in the Dewhurst Stakes at Newmarket.
The following season he won the Group One Haydock Park Sprint Cup and was second to Elnadim in the Darley July Cup at Newmarket.
In his only career start beyond seven furlongs, Tamarisk finished 16th of 18 behind King Of Kings in the 1998 2000 Guineas.
