Paul Pompa Jr., who sold a majority interest in 2008 Kentucky Derby winner Big Brown to the IEAH Stables, has sold a minority interest in his 2009 Derby hopeful This Ones for Phil to owners Jack Mandato and Michael Dubb. Pompa said Thursday he sold a 45 percent share of This Ones for Phil to Mandato and Dubb for "good money," and that he has retained 55 percent of the horse for himself. This Ones for Phil burst into the national spotlight after earning a 116 Beyer Speed Figure for his 2 1/4-length victory in Gulfstream Park's Sunshine Millions Dash on Jan. 24. The gelded son of Untuttable will be the morning-line favorite in a field of 11 3-year-olds who will compete in Saturday's Grade 2 Fountain of Youth. Pompa purchased This Ones for Phil privately from former owner and breeder Gilbert Campbell for $150,000 and turned the horse over to trainer Rick Dutrow Jr. shortly after his 2-year-old finale at Calder on Nov. 8. "I've had lots of inquiries about the horse, but I wanted to make it simple and go with the right kind of people," said Pompa. "Jack Mandato is a philanthropist who wants to be in it for the action. Michael Dubb is always one of the leading owners in New York, and we have a relationship since we both own a piece of Stardom Bound." Pompa also confirmed that This Ones for Phil has been nominated at a supplemental cost of $6,000 to the 2009 Triple Crown.
