Both colts are prepared by Chris Waller, who also trained their sire and both acquitted themselves well on Friday morning.
A Group II winner last season, Zousain was twice Group I placed in the spring finishing second in the Group I ATC Golden Rose and VRC Coolmore Stud Stakes, but has not been able to salute so far as a three year-old.
Last seen finishing unplaced to Sunlight in the Group I VRC Newmarket when he pulled up lame, Zousain looked in good order this morning.
He raced behind the speed for James McDonald before taking advantage of an inside run on straightening, forging clear to win the heat by a length and a half with multiple Group I winning mare Shoals and eye-catching third under a big hold.
The time for the trip was 1.03.4, last 600m in 34.60 second.

He was asked by James McDonald to get another taste of that winning feeling in his heat when ridden out to set a new time standard, running 1.02.8 with a last 600m time of 34.90.
Both Zousain and Lean Mean Machine hold entries in the Group I ATC TJ Smith Stakes against the older horses and the rich $1million Group II Arrowfield Sprint for three year-olds during The Championships.
