Lawbook put himself into position to become the fifth horse to sweep the open division of the Florida Stallion Stakes when he rallied to an easy 4 1/4-length victory over Supah Blitz in the $125,000 Affirmed Stakes at Calder on Saturday. Trust N Luck, the 4-5 favorite, lost his jockey, Gary Boulanger, after wheeling at the break of the seven-furlong dash.
