Arno Kamminga went joint sixth all-time as he scorched to a Dutch record of 2:07.17 in the 200m breaststroke on the second day of the Rotterdam Qualification Meet.
Kamminga had already set a national mark of 26.88 in the 50br on day one before returning for the day two prelims, swimming fast the order of the morning to mirror what the swimmers will be confronted by come Tokyo.
Out in 28.77, the 25-year-old produced subsequent splits of 32.40/32.33/33.67 to take 0.01secs off his own national mark of 2:07.18 set at the Antwerp Diamond Race in March.
In Antwerp his splits read: 29.09/ 32.49/ 32.64/ 32.96 and it followed his effort of 58.43 in the 100br as he became the third-fastest man in history behind Adam Peaty (56.88) and Ilya Shymanovich (58.29).
With that Kamminga had propelled himself to joint sixth all-time alongside Yasuhiro Koseki before Shoma Sato unleashed a 2:07.02 in October to bump the pair to seventh.
Now though Kamminga – coached by Mark Faber at the National Centre in Amsterdam – leaps alongside Josh Prenot who clocked 2:07.17 at the US Olympic trials in 2016.
He remains second in the European record books behind only world champion and world-record holder Anton Chupkov (2:06.12) and ahead of 2012 Olympic champion Daniel Gyurta (2:07.23).
