GAINESVILLE - Calvin Smith, the rising sophomore from Lutz, clocked a personal-best 45.52 to win the 400 meters on Sunday at the NACAC Track and Field Championships.

Smith’s mark eclipsed the PR of 45.60 that he set when he won the SEC outdoor 400 meters title, and improved his hold on 10th place on the school's all-time list. The only American to start the final, he outdistanced the Dominican Republic’s Arismendy Peguero by .11 to capture the gold medal. The three-time All-American won his second gold medal of the meet hours later, when he ran the second leg of the United States’ winning 4x400m relay (3:02.78).
