He originally placed second in the 200 metres at the 2008 Beijing Olympics but was later disqualified due to a lane violation.

Martina secured four and two individual top-five finishes at the Summer Olympics and World Athletics Championships respectively.

The 2004 season also saw much improvement in his times as he knocked 0.16 off his previous year's personal record with a 10.13-second run in Santo Domingo.

[4][5] He led the team to the final at the 2005 World Championships in Athletics and improved the national record further to 38.45 seconds for sixth place.

In the second round of heats he set a new national record in the 100 m, running below ten seconds for the first time in his career with a time of 9.99 s. In the semi-finals he finished third in his race behind Asafa Powell and Richard Thompson, but improved the national record to 9.94 s. He qualified for the final in which he came close to the medals, finishing in fourth place behind Usain Bolt, Thompson and Walter Dix.

The American coaches appealed the decision and upon viewing footage of Spearmon's offence they noticed that Martina had committed the same infraction.

As a result of the disqualifications, Shawn Crawford and Walter Dix, both of the United States, were promoted to silver and bronze respectively.

[10] However, on 24 August, the Netherlands Antilles filed an appeal to the Court of Arbitration for Sport to reinstate Martina's medal, arguing that the American protest came after the 30-minute deadline for protests and appeals set by the International Association of Athletics Federations (IAAF), and also that they had their own video footage (not the official Olympic video footage) showing that Martina never left his lane.

He defended his regional title at the 2010 Central American and Caribbean Games, holding off a challenge from Daniel Bailey to win in 10.07 seconds—just one hundredth off his championship record.

However, after the Olympics, Martina broke the 200 m national record in Lausanne, lowering the time to 19.85, ending his reasonably successful season.
