Roger Beyker Martínez Tobinson (Latin American Spanish: [ˈroʝeɾ maɾˈtines]; born 23 June 1994) is a Colombian professional footballer who plays as a winger or forward for Saudi Pro League club Al-Taawoun and the Colombia national team.

At the age of 17, he was offered to go to Argentina, arriving at Boca Juniors where he was tested for a few months; although they loved him, he could not play official matches because he was not with his parents.

He made his debut for Racing Club de Argentina in a match for the 2013 Copa Sudamericana, in which his team fell to Lanús 2–1, entering the second half replacing Ricardo Centurión.

In 2014, the Racing coach, Diego Cocca, confirmed that he would not take him into account and they transferred him to Santamarina from the second division of Argentine football without a purchase option.

In 2015 the Racing coach, Diego Cocca, confirmed (for the 2nd time) that he would not take him into account and they transferred him to Aldosivi, recently promoted to the First Division of Argentina.

His second goal was against Quilmes after an excellent combination between Jose Sand and Pablo Luguercio (2 ex Racing) where he defined a dive against Fabian Assman.

After having played 27 games, converting 6 goals and having good performances in Aldosivi "El Tiburón", Facundo Sava informed him that he would take him into account for the next season and he returns for the third time to Racing Club de Avellaneda.

On 12 July 2016 he moved to Jiangsu Suning from China in exchange for 9,800,000 euros, with the possibility, in the future, of reaching Inter Milan.

On 27 November he scored a brace in the final of the China Cup in a two-goal draw against Guangzhou Evergrande, where they would lose by a visitor goal as runners-up in the tournament.

On 7 January 2018 his arrival on loan for six months with a purchase option was confirmed at Villarreal Club de Fútbol of the Spanish League where he would be a teammate of his compatriot Carlos Bacca.

He debuted on 10 January, playing the last 18 minutes in the 2–1 victory over CD Leganés although they were eliminated on aggregate by the round of 16 of the Copa del Rey.
