On day 3 of Russian nationals in Moscow, Anastasia Zueva clocked 2:06.59 on her way to the helm of the 2012 world rankings 0.09sec ahead of Australian Belinda Hocking.
Not quite the shiny suit Russian mark of 2:04.94 (second best ever, all suits) but Zueva cracked the Russian textile suit best twice in the past 24 hours, a 2:07.56 in semis getting past her previous best, of 2:07.91, from last year.
The race was also notable for Zueva becoming the fourth woman in textile to get inside the 2:06.69 at which Krisztina Egerszegi, Olympic champion for Hungary in 1988, 1992 and 1996, held the world mark between 1991 and 2008, when shiny suits took over for a limited season that ended with a ban on January 1, 2010.
The all-time top 5 in textile:
The next two sub 2:07s on the list belong to Elizabeth Simmonds (GBR), 2:06.79, and Olympic champion of 2004 and 2008 and world record holder all suits, on 2:04.81, Kirsty Coventry (ZIM), on 2:06.83.
