HALLANDALE BEACH, Fla. – Owner-trainer Happy Alter is rarely at a loss for words when it comes to talking about his multiple graded stakes winner Curlin’s Approval, who is back in serious training again after getting a bit of a break following her fifth-place finish in the Grade 3 Royal Delta here on Feb. 19. But on Monday, Alter was more eager to talk about the newest member of his stable, an unnamed 2-year-old by Tapit out of the Grade 1-winning mare Lady of Fifty whom he purchased here for $500,000 at last month’s Fasig-Tipton select sale.
