Phelps breaks world 100m butterfly record…again


Michael Phelps outraced Milorad Cavic in an enthralling final at the 2009 FINA World Championships in Rome Saturday night and became the first man to swim the 100m butterfly in under 50 seconds.

Phelps rallied on the return leg to beat his Serbian rival with a new world record of 49.82 seconds, bettering his mark of 50.22 set in early July.

The victory gave the Olympic great his second world record and fourth gold of the meet following triumphs in the 200 butterfly, the 4×100 freestyle relay and the 4×200 freestyle relay.

The U.S. medal tally in the pool after day seven stands at 18 and the Americans lead all countries in both gold medals won and in overall medal count.
