Mizunuma Fires Off Sub-52 100 Fly, Omoto Enters All-Time JPN List


Fans were left a little baffled yesterday when South Australian hero and 2016 Olympic gold medalist Kyle Chalmers pulled out of the 100m free final battle against visiting Japanese maestro Katsumi Nakamura. Since yesterday’s finals, Chalmers posted via social media that he has pulled out of the remaining days of competition due to tonsillitis.

This was an in-season, under-training meet for Chalmers, so, at worst, the 20-year-old is simply out opportunities to race some solid competition on his home turf. That meant Chalmers was missing from today’s 100m fly and 200m free events.

In that men’s 100m fly race, Naoki Mizunuma doubled up on his impressive 50m fly victory from night 3 with perhaps an even more head-turning effort this evening in the 100m sprint. After establishing himself as the man to beat during this morning’s heats, clinching a quick 52.13 to lead the field by several seconds, Mizunuma dropped under the 52-second barrier this evening for gold.

Splitting 24.14/27.76, the 22-year-old struck a speedy mark of 51.90 to win by well over 5 seconds and insert himself as the 8th fastest Japanese performer ever in the event, overtaking his pervious season and personal best of 51.98.

However, Mizunuma wasn’t the only Japanese racer to write history tonight in South Australia. His 25-year-old teammate Rika Omoto, who made waves earlier in the meet with the world’s first sub-2:10 200m IM this season, crushed a new personal best in the women’s 100m freestyle tonight.

Carrying a solid morning swim of 55.58 into tonight’s final for the 2nd seed, Omoto swam with abandon, pumping out a winning mark of 54.71 to represent the only racer of the field under the 55 second threshold.  Splits for Omoto include 26.33/28.38 to move her into the season’s world rankings at #15.

More locally, however, Omoto now enters the list of all-time Japanese women as the 7th fastest performer ever.
