Serena's Song, who is owned by Robert and Beverly Lewis, is booked to Unbridled.
Champion Serena's Song produced a bay colt by Storm Cat at Craig and Holly Bandoroff's Denali Stud near Paris, Ky., on Feb. 10. The day before, the colt's half-sister, Serena's Tune (by Mr. Prospector), won her 3-year-old debut at Santa Anita.
