Summary
on the outside and Bralon Taplin in the middle of the track edged out to a slight lead, but down the backstretch it was almost an even stagger across the track. Through the turn, Taplin started to lose ground putting Gaye into the lead coming off the turn. Really as they hit the straightaway, Gaye's one step forward and Anthony Zambrano's one step back were the only thing that interrupted a shoulder to shoulder wall across the track. On the run for home, Taplin and defending champion Luguelín Santos went out the back. Gaye continue to hold the edge as the others struggled. The only one to make a serious forward move was Zambrano, who gained all the way past Gaye to take the win. 17 year old Justin Robinson picked up bronze.Records
