After Stavro's death in 2006, his estate assumed the management of Knob Hill Stable, looking to carry on Stavro's legacy and love of horse racing. That year Stavro was posthumously inducted into the
Canadian Racing Hall of Fame. The 2006 season would prove to be successful for the stables, largely due to one of the horses Stavro purchased at the Keeneland Yearling Sale,
Leonnatus Anteas. Named after one of
Alexander the Great's bodyguards, the two-year-old horse would go on to win all three races he entered, with each race being on a different track surface. For his efforts, Leonnatus was voted 2006 Sovereign Award Champion for 2-Year-Old Horse. Leonnatus quickly emerged as one of the more promising Canadian racing horses and began the 2007 season with high expectations. He was a winterbook favorite for the
Queens Plate race; however, he could not race due to an infection in his
pastern. The three-year-old colt made his next start in the September 15
Super Derby at
Louisiana Downs in
Bossier City, Louisiana, finishing fourth. Even with Leonnatus' injuries, the 2007 season was one of the most successful in the history of Knob Hill Stables. Leading the charge was the Knob Hill Stables bred three-year-old Alezzandro, a derivative of the name of Stavro's hero, Alexander the Great. That year Alezzandro won the
Prince of Wales Stake and finished second in the Queen's Plate, a goal that Stavro strived for his entire life. Alezzandro finished the year 65th in earnings for all of North America and received the Sovereign Award for Champion 3-Year-Old Colt. For the 2007 season, Knob Hill Stables finished with US$1,247,000 in earnings, the second highest earnings in their history. In 2008 Knob Hill Stables saw less success than years prior. Their only major stake win for the season was Nicki Knew, which won the Boston City Stake. Overall, the Stables' earnings were down to US$608,000. The 2008 season would be the last season that Knob Hill Stables won a major stake competition. Over the next four years the breeding program Stavro championed would slow and overall stable inventory dropped sharply. The horses still racing were mainly holdovers from the 2007/2008 season. 2012 would be the last year that the Stable entered horses into racing competitions. In its 40-year career, Knob Hill Stable proved to be one of the premiere Canadian stables. Throughout its history, it produced 85 stakes winners that raced throughout North America and Europe. Knob Hill Stables remains one of the few Canadian stables to win the
Thoroughbred Owners and Breeders Association award for the top owner horse breeder in North America. ==Facilities==
