Phelps issues splashy warning to rivals

Olympic swim legend Michael Phelps completed an epic effort at the US national championships on Monday, having served notice he has the speed and skill to star at the 2016 Olympics.

Phelps only finished fifth in Monday's 200-meter breaststroke final in 2 min, 11.30 sec, well off winner Craig Benson's winning time of 2:09.68.

But Phelps seldom swims the event and was entered more as a challenge and training exercise rather than with a victory in mind, having won three events in the previous three days and beaten the winning time at the world championships in Russia in each one of them.
