Jobodwana bows out in semi
South African sprinter Anaso Jobodwana failed to make the final of the men's 100m in the IAAF World Championships in Moscow on Sunday.
Jobodwana clocked 10.17 seconds to finish fourth behind American Justin Gatlin (9.94), Jamaica's Nesta Carter (9.97) and France's Jimmy Vicaut (10.01) in his semifinal, but placed well down in 16th overall with his time.
Jobodwana could not explain why he did not run a better time.
"I've got no excuses, I ran a bad race," said Jobodwana after his race.
"My start wasn't good and from there on I was trying to catch up."
The 20-year-old said he would change his focus to the 200m on Wednesday, the event where he made the Olympic final in 2012 in London.
"I'm very disappointed. I just have to go back and get it up for the 200."
Meanwhile, decathlete Willem Coertzen set a new African record of 8 343 points.
Coertzen finished ninth, well behind Olympic Champion Ashton Eaton who scored a world-leading 8 809 points.
Coertzen said the competition was fierce at the top level.
"The quality of the field has improved, this is the best quality at the World Champs ever," said the Potchefstroom-based athlete.
"At the Olympics I scored 8 173 for ninth, now I scored almost 300 points more for the same position."
One-lap specialist Wayde van Niekerk was another South African who failed to progress as he bowed out in the 400m heats.
Van Niekerk ran 46.37 to finish fourth in his heat but placed a lowly 26th overall.
"I know I've got better in me... If I didn't give my all I'd be disappointed but I tried my best today...Eish I fell short. Way short, " said Van Niekerk.
"After a blistering start, he led the field into the 200m, but the early pace caught up with him and he faded back in the second half of the race.
