Bertram, Elaine, and Richard Klein's multiple stakes winner Country Day will enter stud in 2013 at Pope McLean's Crestwood Farm near Lexington.
The 6-year-old homebred son of Speightstown will stand for $5,000 stands and nurses and will participate in the "Share the Upside" program.
Country Day captured three stakes and placed in five others. He finished second in the 2011 Breeders' Cup Turf Sprint (gr. II) in which he was beaten 1 1/2 lengths. He exited racing with a win in this year's Colonel Power Stakes over 2010 Turf Sprint winner Chamberlain Bridge.
"Country Day was a very talented horse with tons of class as shown on the racetrack," Richard Klein said. "We look forward to breeding many of our broodmares to him."
Country Day, who raced at nine tracks, won on dirt, turf, and synthetic surfaces. He recorded a 105 Beyer speed figure when scoring by six lengths at Fair Grounds at 3 and a 102 when winning the Hot Springs Stakes at Oaklawn Park the following year. Country Day was retired with a record of 7-4-2 from 19 starts and earnings of $503,829.
"Country Day is the classiest horse I ever trained," said Steve Margolis. "He was very fast and versatile, winning stakes on all three surfaces."
Out of graded stakes winner Hidden Assets (by Mt. Livermore), Country Day is a half brother to multiple stakes winners Due Date and Good Deed. Country Day traces back in female family to Calumet Farm's blue hen Blue Delight, whose other descendants include major winner and sire Alydar.
