On 7 December 2013, Lara fought Austin Trout at Barclays Center in Brooklyn, New York. Considered the favorite to win, Trout had recently beaten Miguel Cotto. Lara, however, put on a dominant performance as he immediately nullified Trout's offense using deft footwork and clean punching. In outclassing Trout, Lara scored a knockdown in round eleven via straight left hand. Trout was hurt for the remainder of the round as Lara pressed the action. Lara cruised to the unanimous decision (117–111, 117–111, and 118–109) and retained his WBA interim super welterweight title.
