No other Jamaican qualified, with Peter Matthews finishing eighth in his heat in 45.42, while Javon Francis was fourth in 44.77. It was a result that left McDonald extremely disappointed and puzzled. “I have to go back home and really train hard and think about this semi-final. Jamaica hasn’t had a good quarter-miler in the final for a few years, so I have to go and work on that,” said McDonald. “The plan was to get to the first 300m, but I just couldn’t get there. I’m not sure what’s wrong with my body, I tried to push it,” added McDonald. “It was a poor race for me. There was no energy. “It looks like it (national record) took a lot out of me, especially with the time we had to recover,” he said. “The race could have been better, but I don’t know what I did wrong in the race. I just felt tired. “It was a good competition. Everyone came to do their best, but I’m not pleased with my time. It was a poor performance,” said McDonald. The youngster will now turn his attention to the 4x400m relays, which starts on Saturday. disappointed BEIJING, China: Jamaican quarter-miler, Rusheen McDonald, admitted that his 43.93 national record run in the heats a day earlier may have contributed to his poor showing in the 400m semi-final round, as he failed to advance to the final at the IAAF World Championships in Beijing, China. McDonald posted his fifth sub-45 seconds time this year, 44.86, but still only managed a sixth place finish in his semi-final, a day after smashing Jamaica’s national record with a brilliant 43.93 seconds run in his heat. The result meant that the MVP Track Club athlete would not realise his ambitions of becoming the first Jamaican to qualify for a men’s 400m final at the World Championships or Olympics since Jermaine Gonzales finished fourth at the IAAF World Championships in Daegu in 2011. The semi-final was won by Isaac Makwala, who clocked 44.11, with Yousef Masrahi, 44.40 and Rabah Yousif, 44.54, finishing second and third, respectively.
