Timboroa is a son of the Topsider stallion Salse, the champion French 3-year-old colt of 1988. According to The Jockey Club Information Systems, Salse has produced 17 stakes winners from his 10 crops of racing age. Salse died at age 16 earlier this year at the Side Hill Stud near Newmarket, England.On the female side, Timboroa is the only winner produced from the unraced Damister mare Kisumu. A daughter of the High Top mare Eldoret, Kisumu is a half-sister to the Italian champion miler and sire Efisio and to grade I Santa Barbara Stakes winner Mountain Bear. Those two horses represent the only black type in the first three generations of Timboroa. His third dam, Bamburi, is a half-sister to two stakes winners.
Timboroa emerged as a top contender for the Breeders' Cup Turf when he won the Turf Classic Invitational in gate-to-wire fashion. That victory was the second impressive win in a row for the British-bred 5-year-old, who previously equaled the course record while winning the Del Mar Handicap.Bred in England by Angmering Park Stud, Timboroa was sold by agent Ted Voute to Panetta Bloodstock Agency for the U.S. equivalent of $42,613 at the 1996 Tattersalls November yearling sale.Timboroa began his career in Italy, where he won his only start at age two for owner-trainer Roberto Brogi. As a 3-year-old the following year, Timboroa was a stakes winner and group I-placed in Rome. At age four, he won Italy's group I Premio Presidente della Repubblica before being purchased privately by current owner Edmund Gann. Wearing Gann's colors, Timboroa raced once in France before being imported to the U.S., where he responded with a victory in the Carleton F. Burke Handicap (gr. IIIT) for trainer Bobby Frankel.
