Can emerging stars of Delhi shine in London in 2012?

These Commonwealth Games were a massive opportunity for three distinct groups of athletes.

Kenyan Boaz Lalang proved he is world class in Delhi

There were the favourites, many of whom came here as the new champion of Europe or Africa in their event and duly added Commonwealth gold to their collection.
Then there were those older competitors for whom this was probably one last opportunity to stand on the podium.
Well done to them, but I've been looking at the most exciting group - the new talent.
This was their chance to gain international experience, to impress and show what they might be able to do in London in two year's time.
Kenya's Boaz Lalang is just 21, but this has been his breakthrough year. He'd won world indoor silver back in March and was second behind his countryman, David Rudisha, in both of those world record breaking races at the end of August.
But here Lalang's mindset had to be different. A gold was expected, and he showed he could handle that pressure in the 800m. He's a front-runner, like Rudisha, and imposed himself in the semi and final in Delhi.
His triumph, leading home a Kenyan 1-2-3, marks him out as one of the best in the world over the two laps. He's definitely a medal contender for London and, before that, at next year's World Championships in Daegu.
Lalang is just about the finished article, but it's not just gold that's caught my eye here.
Remember all the negative headlines about how few Jamaican sprint stars were coming to Delhi? Well, some promising performers have emerged from those that did make the trip. Their 2010 national champion for 100m, Oshane Bailey, looked very good until suffering an injury in the semi-final which prevented him from lining up for the championship race.
Bailey, who only turned 21 in August, ran 10.12 seconds in the second round, just one hundredth outside the personal best he set earlier in the year, and the same time that his team-mate, Lerone Clarke, later clocked to take gold in the final.
My Indian tip for 2012 isn't one of their Delhi gold medallists. It's a 21-year-old who was leading the 800m final until the last 200m.

Australia's Liz Parnov is one to watch in the pole vault

Tintu Luka is India's national record holder for the distance and a front-runner. That takes tremendous confidence in your ability and it didn't work out here. She faded to sixth, but lessons will have been learned, and she will come back stronger.
Also learning about competition at this level was a 16 year old Australian pole-vaulter, Liz Parnov, who'd won silver at the inaugural Youth Olympics in Singapore.
In Delhi, her introduction to senior competition was an 11th place finish. But the event is in her blood - her father Alex coaches the World, Olympic and now double Commonwealth champion, Steve Hooker.
Though she couldn't produce it on Tuesday night, her personal best is already 4.40m - exceptional given her age. She might be the future of her event.
Yes, many chose not to come here and others that did turn up won golds pretty easily, but keep an eye on the athletes I've mentioned. London could be their Games.
