Favored Our Song took full advantage of a ground-saving trip by jockey Edgar Prado and pulled away for a two-length victory in the final race Friday at Saratoga, a $45,000 maiden affair filled with some potentially top 3-year-olds.Einar P. Robsham's Our Song, a son of Unbridled Song purchased for $310,000 at the Keeneland September 2000 Yearling Sale, went 7 furlongs in 1:24 to register his first win from six career starts. It was his second start of 2002.America's Storm, owned by Padua Stables, Olin Gentry and John Gaines, who paid $3.6 million for the son of Storm Cat in the same sale, was second under Pat Day after battling Our Song for the lead through early fractions of :22 4/5, :45 4/5 and 1:11 for six furlongs. It was America's Storm fourth career start and third in-the-money performance. Godolphin Racing's Canadian Frontier, a son of Gone West out of the outstanding race mare Borodislew purchased for $325,000 in the same Keeneland sale as was his rivals, broke poorly in his debut effort, rallied into the turn and faded in the stretch to finish out of the money. Ogden Phipps' Abduction, a son of Seattle Slew also in his first race, was not a factor.Our Song paid $8.60, $4.20 and $3.40 to give Prado, Saratoga's leading rider, his fourth win of the day. America's Storm returned $5 and $3.90. The show horse, Phish, paid $4.80.
