HALLANDALE BEACH, Fla. – Eibar Coa walked around the Gulfstream Park jockeys room just like old times Thursday, his miraculous recovery from the horrific spill here that had left him temporarily paralyzed last winter now well documented. But Coa’s visit had less to do with greeting old friends than being a proud papa, showing his 19-year-old son, Kieber, the ropes in preparation for accepting his first U.S. mount aboard Primpfedenel in Saturday’s second race.
