Daley will be Britain's second youngest male Olympian
Teenage diving star Tom Daley beat his British team-mate Pete Waterfield to claim an individual silver medal at the Fina World Series event in Sheffield.
The 14-year-old, who won gold with Blake Aldridge in Saturday's 10m synchro, edged out the Olympic silver medallist into the bronze position.
Daley, due to compete at the Olympics, said: "There are a lot of tweaks I need to make but this is a learning curve.
"I'm really excited about this year and this has been another stepping stone."
Further British successes came from Monique McCarrol and Sarah Barrow, who won silver in the women's 10m platform, and Ben Swain and Nick Robinson-Baker, who secured bronzes in the men's 3m synchro.
Barrow said: "We are very happy with the silver against a field of the world's best divers who will all be in action at the Olympics. We can still improve, it wasn't as good as we've been in training but we are getting there."
