Aussie Stubblety-Cook Becomes 7th Fastest 200 Breast Performer All-Time


While competing on the first non-relay day of Queensland Championships racing at the Brisbane Aquatic Center, 20-year-old Zac Stubblety-Cook became the 7th fastest 200m breaststroke performer of all-time.

After claiming the top seed of the morning in a time of 2:10.24, Stubblety-Cook dropped the hammer to power his way to a ferocious 2:07.28 to take the state title in a Queensland Record and QLD All Comers Record. That easily beat out runner-up Olympian Yasuhiro Koseki and his time of 2:12.48. Koseki and his fellow compatriots are competing in Queensland in the midst of a training camp.

Splitting 1:01.71/1:05.57, Stubblety-Cook’s 2:07.28 shaves .08 off of the swimmer’s previous lifetime best of 2:07.36 produced in Gwangju, Korea this summer at the World Championships.

With all eyes on fellow Australian Matt Wilson, who logged a World Record in the morning of that meet and ultimately finished with the silver, Stubblety-Cook quietly finished in 4th place. Splits for that 2:07.36 outing included 1:02.04/1:05.32, showing how the man relied on quicker speed on the front end when comparing the two races.

The only other time Stubblety-Cook had been sub-2:08 was en route to winning silver at the 2018 Pan Pacific Championships. He earned runner-up behind former World Record holder Ippei Watanabe in a time of 2:07.89.

Even with just a .08 best time drop to his new low of 2:07.28, Stubblety-Cook moves from having been the 11th fastest performer to now entering the top 10 at slot #8, according to the USA Swimming database. That’s a huge confidence boost for the man from down under heading into the final months of Olympic Trials preparation.

Sublime breastroker, Zac Stubblety-Cook, one of the brightest talents in the 200 br. And he has lot of room for improvements in his weakest parts: the start and the turns.


I don’t understand what you mean saying “weak start”. His reaction time was 0.7sec. How much do you think he has for improvement here and how much it’s important. It isn’t a 50FR sprint, it is 200BR.


He isn’t talking about getting off the blocks. It’s about once happens when he hits the water before he starts the swimming part of the race.


You mean his underwater part of the race: from start and from walls. And how weak is this guy with that (in meters, seconds, whatever) and how much the improvement of this part of the race can give him (in seconds).


Hi Yozhik, like Samboys and Samuel Huntington wrote, I meant the whole “start phase”, not just the RT.
The same about the turns (so, also the underwaters). You can watch the 200 breastroke final on last June at Aussie trials in comparison of Matt Wilson or, even more visible, the Worlds final in Gwangju vs the other finalists. Was fairly impressive the amount of tenths at the start and every turn lost by Stubblety-Cook.


Thank you. I just wanted to be clear about your terminology. Also since backstroke rules allow only one dolphin kick I thought that underwater part of the race shouldn’t be much different for different swimmers. So I was wondering how much in seconds can be saved by improving significantly this part of the race.


Have you never watched Peaty in SCM as he loses his lead every turn?


It’s completely terrible.

He would be the slowest 100 breaststroker to the 15 in every world class meet he has ever been at. And comfortably so.

Mediocre age groupers would beat him to the 15.

He is like anti-dressel. Imagine the lead dressel has at 15m, and that’s how far Zac is behind.

The rest of the race he is unmatched.

Samuel Huntington

A start is a lot more than just reaction time!

If the start is only about the RT, then people wouldn’t be saying dressel is so dominant on the start


Imagine thinking reaction time = start

Old Man Chalmers

But then again, its yozhik. he’s well known for his hosszu bashing and is on the record for saying that IMs are farcical events


Old man you still don’t get it. I’m not bashing a swimmer Mrs. Hosszu. I’m criticizing those who are spreading some BS about her.


The current global depth in the 200 br is amazing. Going 7th fastest time in HISTORY and most people still won’t consider him as a favorite or even a lock for a medal


I’m loving the domestic rivalry happening with matt wilson though.. like the good old days of Rickard v Sprenger .. there was a big hole in men’s breastroke for a while


Russians and Japanese have been deep in breast talent at the top end and lately Australians have show they are competitive too!


Good swim from Zac PB by 0.08, hope he can get down to 59mid in the 100 this meet!


Yup 100 breast is still a problem depth wise for Australia .. it’s what could cost a medley relay medal in Tokyo … I think Jake Packard has plateaued as well as he’s just hovering 59.2 at his best while others are passing him now into 58s territory
