In his next fight, which took place nearly three years later on 31 March 2008, Barroso scored a first-round stoppage over Rafael May; his first of many knockout wins.
Barroso's first outting on a major stage came on 12 December 2015 on the undercard of Anthony Joshua vs. Dillian Whyte against Kevin Mitchell for the vacant WBA interim lightweight title.
From the opening round, Mitchell was unable to fend off Barroso's highly aggressive southpaw style, who scored three knockdowns.
[1] On 7 May 2016, Barroso endured a reversal of fortune when he faced Anthony Crolla for the WBA lightweight title, having travelled to England for a second time.
Despite getting off to a similar start as he did against Mitchell, landing many hard punches and backing Crolla up, Barroso's onslaught began to wane in round five.
