Former Dagenham & Redbridge youngster Adam Gemili booked his date at London 2012 with a second place finish in the 100m at the Aviva London 2012 Olympic Trials.

It was Dwain Chambers who crossed the line first but a top-two placing for Gemili means the 18-year-old has done enough for automatic qualification into the Games.

The Blackheath competitor finished first in his heat on Friday in 10.27 before again leading the field home in the quicker time of 10.20 in the semi-final.

And Saturday’s final saw Gemili run his slowest time of the meet (10.29) but still do enough for second place and earn a spot for Team GB having already achieved the Olympic A standard at the Sparkassen Gala in Regensburg, Germany.

His run of 10.08 in Germany means he is the fastest Brit this season and the second fastest in Europe however, coach Mike Afilaka has stressed a decision will not be taken on whether Gemili takes up his Olympic place just yet.

Afilaka wants to make sure Gemili is prepared to compete on the world’s greatest stage, considering he is not just a young competitor but also new to the sport.

“We have an issue with good young kids who just don’t develop. You throw Adam into the cauldron of the Olympics and he gets burned and he might never recover,” he is quoted in the Daily Telegraph.

“I’m talking about being mentality burned, not physically burned. I mean, you have a number of British athletes that do well on their own but sprinkle a couple of Americans in the mix and they can go blank. The development of any athlete is not just physical, it’s mental as well.

“I’m not saying we’re not going to go to London. I’m just saying right now the priority is the World Junior Championships and then we’ll adjust accordingly.”
