Claros started his career at Vida before joining Honduran giants Motagua in 2005. In January 2012 he went on trial at Scottish club Rangers. He then went on trial with another Scottish club, Hibernian, and he signed a loan contract with Hibernian on 31 January. Claros helped Hibernian to reach the 2012 Scottish Cup Final, but he was substituted during the first half of a 5–1 defeat to Hearts. Despite this performance, Hibs manager Pat Fenlon claimed that Claros would improve during the 2012–13 season. On 16 January 2013, Hibs stated that the clubs were in discussions about the possibility of extending the loan agreement. Later in January, the deal was extended until the end of the 2012–13 season. Claros helped Hibernian reach the 2013 Scottish Cup Final, which ended in a 3–0 defeat to Celtic. He was offered a long term contract by Hibernian, but returned to Motagua because they continued to demand a large transfer fee.
Claros was shot in the head on 16 June 2011 after car thieves failed to steal his vehicle. As he stopped his car to drop off a friend, 2 unidentified men with pistols shot at them, and Claros was hit in the shoulder and in the head. Claros managed to drive himself to the hospital and it was found that the wounds were not near fatal. Within three weeks Claros was back playing football for Motagua, his club at the time.
