Tom Daley unhappy with 10m platform performance

Tom Daley has described his performance in the preliminary round of Friday's 10m platform as his 'worst of the year' as he edged into the semi-finals of the competition.

With the top 18 going through, it took a successful final dive from the Brit to book his place in the next round.

"If I was going to have a bad competition today was the best to do it on," he told BBC Sport.

"It was definitely the worst I've dived all year so I will have to turn it around in the semi-final.

"It's nerve-wracking because you don't know what is going to happen, in my last dive it was now or never and thankfully I made it."

Daley's Team GB teammate Peter Waterfield could only finish 23rd as he exited the event.
