Olympics diving: Tom Daley scrapes into 10m semi-final

British diving star Tom Daley endured a torrid preliminary round in the 10m platform as he edged through to Saturday's semi-finals.

A poor start was compounded by a sloppy fifth dive to leave him in 16th place with a round to go.

The 18-year-old did just enough with his final dive to move up to 15th, with the top 18 in the 32-man field progressing.

But team-mate Peter Waterfield could only finish 23rd and is now out.
