In one of the most awaited finals of the programme, Vladimir Morozov, from Russia, had a bullet-start with a 0.59 reaction time and a 50m turn under the World Record pace (21.94, 0.23 faster than the split clocked by Cielo in 2009), but this initial effort didn’t pay off. The victory went to Australia’s James Magnussen in 47.71, 0.08 slower than his winning time in Shanghai, two years ago.
Magnussen had been defeated by Nathan Adrian (USA) at the 2012 Olympics, but took his sweet revenge in Barcelona, leaving the minor medals for the two US swimmers of the final, respectively James Feigen (47.82) and Adrian (bronze, in 47.84). The Australian sprinter was already the best performer of the season, with a 47.53 effort from last April in Adelaide. Moreover, this was his fourth medal at FINA World Championships, after three podium presences in 2011.
For the North American swimmers, Adrian accumulates his fifth award, while Feigen takes home his second medal at this level. Morozov was fifth in 48.01, while Fabien Gilot from France could not get close to his 46.90 effort in the third leg of the 4x100m free relay on Day 1 and finished seventh in 48.33.
