National Treasure is the winner of the 148th Preakness Stakes.  Hall of Fame trainer Bob Baffert’s colt outlasted Blazing Sevens in a thrilling stretch duel on a bittersweet day at Pimlico.  Baffert’s Havnameltdown suffered a leg injury in an earlier race and was quickly euthanized on the track.  Jockey Luis Saez was taken to a hospital.  National Treasure’s win made Baffert the winningest Preakness trainer in history, breaking a tie with 19th century trainer R. Wyndham Walden.
