Washington: Michael Phelps edged Ryan Lochte to win the 200-metre freestyle final at the US Olympic swimming trials.

Phelps, the former world record-holder and reigning Olympic champion, led throughout the final to win in one minute 45.70 seconds, while Lochte, who beat Phelps in the event at last year's Shanghai worlds, trailed at 1:45.75 Wednesday. Both of them booked an Olympic berth in the discipline, reported Xinhua.

The two already booked a place in the 400m individual medley for the Olympics. Lochte beat Phelps here Monday in the trials.

Only the top two finishers in each event in the eight-day meeting secure places in the Olympic team. (IANS)
