Mark Crear's bronze made him the 10th man to win a second medal in the event.
Anier García accelerated his first few steps better and gained a few centimeter lead over the first barrier, which he rattled.
Defending champion Allen Johnson was close to Garcia, and even after clobbering the first two hurdles, he was pulling even.
Garcia had a metre and a half lead at the finish over Trammell, and while Crear did hit the last hurdle he was able to beat Johnson to the line for bronze.
[2] Barbados, Liberia, São Tomé and Príncipe, and Trinidad and Tobago each made their first appearance in the event.
