Born in La Unión, Zacapa, Cordón was named after former England international footballer Kevin Keegan,[2] of whom his father was a fan.

Cordón then competed at the 2011 BWF World Championships in London, where he reached the quarterfinals after beating fifth-seeded Chen Long from China, Henri Hurskainen from Sweden and Pablo Abian from Spain to face the tournament's top-seeded Lee Chong Wei.

[5] Cordón was selected as the flag bearer for the Guatemalan team at the opening ceremony of the 2011 Pan American Games,[6] and was also the top seeded player in the men's singles event.

He won both of his group matches, beating 15th seed Englishman Rajiv Ouseph and Swedish player Henri Hurskainen in the process, thus winning a place in the round of 16.

He qualified again to the 2016 Summer Olympics, but had to withdraw due to injury after finishing the first match, losing a tough 3-setter against Adrian Dziolko of Poland.

He lost the semi-final to eventual gold medalist Viktor Axelsen of Denmark and the bronze medal match to Indonesian Anthony Sinisuka Ginting, both in straight games.
