[1] Solinus was sent to the United States and was consigned to the Saratoga Yearling Sales where he was bought for $75,000 by representatives of California businessman, Danny Schwartz.
Ridden by Lester Piggott, he started the 7/4 favourite and won by three lengths from Sharpen Your Eye, having taken the lead shortly after half way.
He took the lead and quickened two furlongs from the finish but was overtaken in the closing stages and beaten three quarters of a length by Sexton Blake.
He made his first appearance in the Group Three Ballyogan Stakes at Leopardstown Racecourse in early June and started second favourite behind the four-year-old Ballad Rock.
Three weeks later, Solinus was moved up in class for the Group One King's Stand Stakes over five furlongs at Royal Ascot in which he was ridden by Piggott and started the 4/6 favourite.
Despite rumours that he had sustained an injury a day earlier, he started favourite and won easily by three lengths from Spence Bay.
[2] He died in 1979 after a single season at stud, with the best of his offspring being the filly Henry's Secret who finished second in the Princess Margaret Stakes and was rated 108 by Timeform in 1982.
