Summer Squall euthanized

Summer Squall, sire of Kentucky Derby and Preakness Stakes winner Charismatic, was euthanized Tuesday because of the infirmities of old age.

The 22-year-old stallion was bred by and stood stud at Will and Sarah Farish's Lane's End Farm in Versailles until his retirement in 2004.

Summer Squall "was an important part of one of Lane's End's great families," Farish said.

The son of Storm Bird and the great broodmare Weekend Surprise, he was a half-brother to top sire A.P. Indy, who also stands at Lane's End.

In addition to Charismatic, Summer Squall sired Breeders' Cup Juvenile Fillies winner Storm Song and Grade I winner Summer Colony.

Summer Squall won the Preakness Stakes for Cot Campbell's Dogwood Stable in 1990 after finishing second to Unbridled in the Kentucky Derby.
