Gwangju - American Caeleb Dressel broke the world record in the men's 100
metres butterfly Friday, obliterating Michael Phelps's old mark with a
jaw-dropping semi-final swim.
The defending champion turned over half a second inside world record
pace before driving home to clock 49.50 seconds in Gwangju, 0.32 quicker
than American legend Phelps went at the 2009 world championships in
Dressel, who swept seven gold medals at the 2017 world championships,
looks on course to match or even surpass that in South Korea this week.
The 22-year-old has captured three already and appears untouchable in the 100m fly.
Dressel exploded from the blocks in the second semi-final and was quickly half a body length clear of Russian Andreo Minakov.
The tattooed pin-up accelerated away after the turn to beat the
Russian by almost two seconds, celebrating by raising a clenched fist in
the direction of flag-waving American fans.
Phelps has now had both of his long course butterfly world record
wiped out this week after Hungary's Kristof Milak destroyed his 2009
mark in the 200m fly.
