LONDON, England - Execution was the buzz words for two of the three Jamaican 100m who all easily won their first round heats here on the second day of the track and field program at the 28th Olympic Games here at Olympic Stadium in Stratford, London this afternoon.

Defending champion and World Record holder Usain bolt, Asafa Powell and World Champion Yohan Blake all won their heat easily to advance to tomorrow’s semi-finals and possibly the final.

While Bolt and Powell stopped to talk to the media, Blake said he was told by his coach Glen Mills not to say anything.

Blake tried to avoid walking through the mixed zone heading directly to the athletes’ area but officials went for him and as he walked through told members of the media that he was told not to say anything.

Bolt cruised to a 10.09 seconds (+0.4m/s wind), Powell won in 10.04 seconds (0.0m/s) while Blake ran 10.00 seconds (+1.3m/s) as the Americans Ryan Bailey who equaled his personal best 9.88 seconds and Justin Gatlin who looked full out for 9.97 seconds set the pace at the top of the ranking.

Both Bolt and Powell said they were satisfied with their performances despite minor hitches.

Bolt said he started well was "stumbled" on the fifth step while Powell's blocks slipped as he pushed off at the start but said that did not affect him.

“It was a good race overall,” said Bolt who was racing for the first time since he lost to Blake at the JAAA/Supreme Ventures National Trials in late June, “I was happy with the performance, (my) reaction was good but I stumbled on the fifth stride but overall it was a good race."

Bolt said they had been working on his start but said it was not a major concern and they were more focused on his middle phase and end of the race where he was strongest.

Powell admitted his groin was not 100 per cent healed but said his mid set was much improved, "Its all about confidence," he said "I really learned how to control my anxiety, control everything that is around me and just focus on myself."

He said it felt good "to just get the cobwebs out and just make sure I am in front," adding that he "executed quite well."
