2018 Pan Pacs Preview: Japan & U.S. To Trade Blows In Men’s BR Events


When speaking of historically-great breaststrokers, the Japanese men are at the forefront of the conversation. Since 2002 – Kosuke Kitajima, Akihiro Yamaguchiand Ippei Watanabe (the current record holder) have all held, for various durations, the World Record in the 200 breast.

With Kitajima retired and Yamaguchi out of the competitive picture, a crew of Japanese breaststrokers led by Watanabe and 2017 World Championship silver medalist Yasuhiro Koseki will lead the charge in a home-country championships. However, it isn’t guaranteed gold for the Japanese with American swimmers Josh Prenot, Andrew WilsonMichael Andrew, and …Caeleb Dressel?… competing. Australian duo Jake Packard and Matthew Wilson along with Brazilian Joao Gomes Jr(in the 100) will be challengers as well.

For all intents and purposes, though – look for this to be a two-way battle between the Japanese and Americans. In the 100, Koseki – 4th place finisher at last summer’s World Championships (59.10) – is the prohibitive favorite being the only swimmer in the field to break the 59-second barrier (58.78), which he set in-season this year at the Mare Nostrum in Monaco. The 26 year-old will have a fend off a pair of relative newcomers on the international stage in Wilson and Andrew. While the former DIII Emory University swimmer Wilson has yet to make an Olympic or World Championship team, he has been lurking over the last 4 years – swimming 59 on 14 different occasions since 2015. If there is anything valued on par with experience, it’s consistency.

On the other hand, Andrew is riding high coming off of 4 National titles (50 free, 50 fly, 50 breast, & 100 breast) at last week’s U.S. Nationals in Irvine, CA. While the 19 year-old’s lifetime best of 59.38 set last week is slower than Wilson, it’s hard to bet against the hot hand – and Andrew is exactly that. We could easily see a 58+ from him in Tokyo.

In the 200, again expect Koseki to fight for a title. After all, he is the silver medalist from last summer’s World Championships in Budapest (2:07.29). In that final, he clipped Japanese teammate Watanabe (3rd – 2:07.47), who is the current World Record holder (2:06.67 – January 2017) and first man to ever break the 2:07 barrier. These two aren’t one-hit-wonders, either. They both placed top 8 at the 2016 Olympics in Rio with Koseki in 5th (2:07.80) and Watanabe in 6th (2:07.87). The biggest question coming into the meet is whether or not Watanabe can get back down to his WR – because if he doesn’t, someone else (*cough* Koseki, *cough* Prenot) likely will.

Do not expect this to be a 1-2 finish for the duo, though. American Prenot – the 2016 Olympic silver medalist (2:07.53) – is back on top after failing to qualify for last summer’s World Championships. The 2:07.28 he notched last week for the win at U.S. Nationals scared his own American Record (2:07.17, 2016 Olympic Trials) and marked the 9th fastest performance of all-time. With a lifetime best of 2:08.37, Wilson will be a factor for a podium finish here as well.

The ultimate wildcard will be the 3rd American Chase Kalisz should he choose to swim it. The 24 year-old set his lifetime best of 2:09.90 back in May of this year at the in-season Pro Swim Series in Indianapolis. After splitting a 1:07.6 last summer en route to World Championship gold in the 400 IM, there is no reason to believe he couldn’t dip into the 2:08 low range. However, with only two athletes per nation allowed to swim in the championship final, Kalisz would have to knock off Prenot or Wilson – which would not be a simple task.

It took MA 2 years to drop .5 in the 100 breast and you think he’ll drop .4 in two weeks to get down to 58? “We could easily see a 58+.” I won’t bet against my boy but that’s pretty high expectations.

Go Bearcats

That’s the thing about his training plan.. I feel like we’ve seen all the cards he has already this season and there won’t be many more drops from him.

too impressed

That said, he has been dropping time across the board lately. With his 100 fly drops, I wouldn’t be surprised to see even more in the 100 breast

I agree with this statement and I’m a big believer in USRPT. I think he purposefully peaked for Nats knowing he needed to qualify and that he’ll be able to equal those times at Pan Pacs anyway. I think some people say it as a bad thing that he swims near his top form so frequently. How is that bad to always be close to your PB?


I find people who refer to swimmers as ‘my boy’ or ‘my girl’ a bit creepy- unless you are their parent.


Hey you cut that quote short. The full quote includes, “58+ from him in Tokyo”…maybe that’s meant to be Tokyo 2020…we don’t know…it’s never specified


I am wishing Prenot to kick some ass in the 200 this year ….they will be great battles between those 2 nations without a doubt . Wilson could well be a threat in the 100 ….lets see how much he can drop .


Chupkov could very well put that world record out of reach before pan pacs


We haven’t seen Murphy in full swing as yet – just a snippet i think last week . He did look powerfully easy on that 50 & 100


Ryan Murphy does breaststroke?


As I saw at the beach everybody swims breaststroke.


me too lol

For people who do not know how to swim, the breaststroke can be easier to learn than the crawl–of course, I am not talking about swimming fast.

Drama King



Chupkov is currently the breastroke goat 1 he wears a necklace! 2 he doesn’t streamline haha
