Callback is the third stakes winner of 2015 for hot young sire Street Sense, whose dozen 2014 stakes winners include multiple Grade I winner Sweet Reason and Australian Group I winner Hallowed Crown. The one chink in Street Sense's armor as a potential Classic sire is that he seems to be throwing more speed and less stamina than might be expected from his own race record; the average winning distance of his stock is only 7.2 furlongs, longer than average for North American sires but distinctly shorter than proven stamina sources such as Dynaformer and A.P. Indy.
Whether Callback will want much more than a mile is a good question, given that her broodmare sire is the pure speed sire Forest Wildcat; further, she is a half sister to the stakes-winning sprinter Defy Gravity (by Bandini). While her dam Quickest is a half sister to 2010 Kentucky Derby winner Super Saver (by Maria's Mon), she is also a half sister to Grade III winner Brethren (by Distorted Humor), whose best performances were at 8 and 8.5 furlongs.
Through her dam Supercharger (by A.P. Indy), Quickest is part of a burgeoning clan descended from the Mr. Prospector mare Get Lucky, herself a descendant of one of the best branches of the family of the great matron La Troienne. Other top members of Get Lucky's family include Grade I winners Bluegrass Cat, Girolamo and Imagining.
Horses from this family have shown a wide range of distance aptitudes, so where Callback will fit in is anyone's guess. Based on the proclivities of her sire and broodmare sire, we may already have seen her best trip. Still, even if she never earns another penny, she has just increased her value to a good deal more than the $375,000 paid for her at the 2013 Fasign-Tipton Saratoga yearling sale. And if she can stay further than a mile, she just may have a sheaf of lilies in her sights in the Kentucky Oaks (USA-I) later this spring.
