HALLANDALE BEACH, Fla. – Trainer Phil Serpe has been a fixture during the winter at Gulfstream Park for nearly three decades. But not since 1992, when Serpe won 18 races, has he had a season in South Florida like the one that ended over the weekend with a pair of victories, including Lady Joan’s front-running half-length triumph over the odds-on Thewayiam in an optional claimer on Saturday.
