The records were tumbling at the Tatsumi International Swimming Centre on night two finals of the FINA World Cup in Tokyo on Wednesday.

The main development is the lead Sweden's Sarah Sjöström continues to build over reigning World Cup champion and Iron Lady Katinka Hosszu in the point standings.

LIVE RESULTS

Daiya Seto signaled his intentions early during the 400m IM, splitting 53.9 in the fly to be under Ryan Lochte's world-record pace for 300m, only to fade towards the end — unable to match Lochte’s 54 freestyle leg but still break his own World Cup record from Beijing. His splits: 53.9/1:00.1/1:06.7/56.6. Insane.

1. 3:57.66 – Daiya Seto (World Cup Record) 
2. 4:03.38 – Peter Bernek
3. 4:03.72 – David Verraszto

Sprint queen Sarah Sjöström also broke a World Cup record on Wednesday night in the 100m fly. Like Seto, Sjöström was out under world-record pace for 50m, splitting 25.8, only to fatigue in her second swim of the night to miss her world record by 0.4 seconds.

3. 56.89 – Yufei Zhang

Sjöström must have been swimming angry after getting outraced by Ranomi Kromowidjojo moments before the 100 fly in the 50m freestyle. These two have been trading world records in this event for some time now. Kromowidjojo gets the result in Tokyo after seeing Sjöström beat her at the last three World Cup stops. Look for this mark to be smashed next month at the Europeans in Denmark.

Japan’s brightest female star, Rikako Ikee, broke two world junior records on Wednesday night to go with her one from Tuesday night's 50m fly. Pushing world champion Katinka Hosszu all the way in the 100m IM, Ikee followed up by trailing Sjöström in the 100m fly. Both previous records were from Ikee at last year’s edition of this meet. She is certainly a star of the future.

3. 58.00 – Emily Seebohm

The Iron Lady lived up to her name, attempting an excruciating triple within the first 30 minutes of the program. After winning her pet IM event, Hosszu placed third in the 200m backstroke, following a stunning 29.1 final 50m. But a negative split race from Emily Seebohm stole the show from Hosszu and rising star Regan Smith of the USA junior national team.

China’s Bingjie Li regained her world junior record in the 400m freestyle after it was broken by teammate Jianjiahe Wang four days ago in Beijing. Li, the dual silver medalist from this year’s Budapest World Championships, finished ahead of Boglarka Kapas and Jie Dong, after all turned together at the 200m mark in 1:58.

Chad le Clos had a pair of tough 200s back-to-back on Wednesday night, first controlling things in the 200m fly with a comfortable win in 1:50.7. Out in 52.7 under his own world-record pace from 2013, le Clos is showing his easy speed is on. With Seto set to contest this race at the upcoming Singapore World Cup, this matchup is mouth-watering.

3. 1:51.57 – Zhuhao Li

Australia’s Cameron McEvoy stepped up for his first medal of this year’s tour, getting the better of le Clos in the 200m freestyle. While both were out much slower than in Beijing, McEvoy surprised with a back half to take the race in 1:43.37.

World champion Jiayu Xu established his dominance in the sprint backstroke events at this cluster, dropping a 49.8 to win the gold medal to go with his gold over 50m in Beijing. Xu will race both the 50m and 100m at the next stop in Singapore.

In a thrilling race, short course world champ and current world-record holder Alia Atkinson again went for the fly and die strategy in the 100m breaststroke, only to be pipped at the finish by a fast-charging Yulia Efimova.
