Asafa Powell (100m)

"I am not 100 per cent but in good enough shape to qualify. I am still suffering from the ankle injury. It's not better yet, so I am not going as fast as I want to. I just want to qualify. I know I won't be under pressure to make the team," he said.

Michael Frater (100m)

"I had some injuries in the middle of the season, but I am fully recovered now and ready to go. It will be very competitive. You have the world's fastest man and the second-fastest man ever, so you can't ask for more competition than that. I am just going out there to do what I do. Anybody who goes into a race expecting to lose, automatically is going to get beaten. The chances of winning are difficult, but its track and field and you don't know what will happen on any given day."

Shelly-Ann Fraser (100m)

"I am in pretty good shape right now. I have been working hard and following the instructions of the coach. I am just looking forward to going out there and doing my best to make the team. Everybody is working hard to be that breakout athlete and to stamp their dominance on the sport. I am always expecting good competition from the other girls. I know that they are capable of doing just that. I am going out there expecting everybody to be a competitor."

Shericka Williams (400m)

"Everybody is coming with their best performance. You can't underestimate anybody, so I just have to go out there and do what I have been taught in training."
