Athletics at the 2015 Pan American Games – Men's 4 × 400 metres relay

The men's 4 x 400 metres sprint competition of the athletics events at the 2015 Pan American Games will take place between the 24 and 25 of July at the CIBC Pan Am and Parapan Am Athletics Stadium. The defending Pan American Games champions are Noel Ruíz, Raidel Acea, Omar Cisneros, William Collazo, Júnior Díaz, Amaurys Valle and Amaurys Valle of Cuba.

Prior to the final, Cuba was disqualified for a registration violation (not naming their athletes before the deadline). Cuba ran in the final under protest and finished in second place. The disqualification was upheld and their result was removed. Later that was corrected and Cuba was reinstated as the silver medalists.

The final race started with the tall Venezuelan Alberth Bravo taking a commanding lead, making up the stagger on the diminutive Renny Quow from Trinidad and Tobago to his outside. Reality set in on the home stretch, Quow holding form on a more evenly paced race while Bravo tied up. TTO passed first while Bravo ended up passing last to a flat footed José Meléndez. Michael Mathieu sped through the turn to put Bahamas in the lead at the break. Jarrin Solomon and Adrian Chacón had TTO and Cuba fall in behind, putting a gap on USA leading the rest of the field. As they battled on the final straightaway, James Harris bridged the gap to make it a four team breakaway at the handoff. With Bahamas (Alonzo Russell) and Cuba (Osmaidel Pellicier) battling for the lead, Marcus Chambers fell off the back for USA on the backstretch while hurdler Emanuel Mayers for TTO tied up at the finish, allowing USA to hand off third well behind the leaders. Bahamas had a two-metre lead at the handoff, which Jeffery Gibson quickly extended to five through the turn. Another five metres back Machel Cedenio used his inside position to get the jump on American hurdler Kerron Clement. Down the backstretch and through the final turn, Cuba's Yoandys Lescay slowly whittled down Gibson's lead. By the head of the stretch it was down to a metre, with Cedenio and Clement 8 metres back. Coming off the turn Lescay moved into lane 2 and eased past Gibson, whose strides noticeably shortened. Behind them, Cedenio came off the turn wide into lane 2, with Clement looking to take advantage accelerating on his inside. Instead, Cedenio exploded into a different gear, sprinting while the rest of the runners were trying to maintain their stride. In 60 metres he made up the gap on Lescay, passing him 8 metres before the finish for the Trinidad and Tobago win. Clement followed Cedenio, passing the struggling Gibson for bronze but still four metres behind Lescay.
