Blueseventy Swim of the Week: Baker, King, Worrell, Manuel Nail WR


Disclaimer: BlueSeventy Swim of the Week is not meant to be a conclusive selection of the best overall swim of the week, but rather one Featured Swim to be explored in deeper detail. The BlueSeventy Swim is an opportunity to take a closer look at the context of one of the many fast swims this week, perhaps a swim that slipped through the cracks as others grabbed the headlines, or a race we didn’t get to examine as closely in the flood of weekly meets.

Like we did last week, we’re using our blueseventy Swim of the Week to count down the world records from the World Championships, this time focusing in on the world records from the second half of the meet: days 5 through 8. As we joked last week, this is a completely objective exercise that should produce 100% agreement among fans, but if you happen to disagree, feel free to leave your own rankings in the comments section.

#4: Team USA – Mixed 4×100 free relay – 3:19.60

Once again a mixed relay finishes at the end of this list, mainly because the mixed relays haven’t been around long and haven’t really been taken seriously by federations until this year. But this one feels more impressive than the medley based on how great the splits were and how massive the record-breaking margin was. To illustrate, here’s a super-exclusive excerpt from a SwimSwam internal communication as we worked on previewing this event pre-meet:

A SwimSwam Senior Reporter who shall remain nameless: “Looking at mixed free relay – I think the pick order is good, but 3:19.6 feels really fast for the US when the world record is 3:23.0.”

In order to really rub it in a bit further, the U.S. relay went 3:19.6 on the dot. The splits are great, though – about as good as could have been predicted for any of the four. Caeleb Dressel was 47.22 leading off, which was far better than anyone projected. Nathan Adrian went 47.49, which was four tenths faster than his individual swim. Mallory Comerford was 52.71 – a little off her season-best, but also faster than any of her three individual 100 frees. And of course Simone Manuel was 52.18, her best split ever and a tenth faster than she went in winning the world title.

#3: Lilly King – 50 breast – 29.40

Another great record for King. This one had been around a sneaky-long time, standing since 2013, which is starting to feel like the distant past. It’s also worth noting that the record didn’t first crack 30 seconds until the supersuit era, and King is just the third swimmer to break the record since the suit ban.

Bonus points to King for winning the de facto tiebreaker over rival Yulia EfimovaKing won the 100 breast, Efimova the 200, but King made of two-of-three with this win. Plus, King broke world records in both her races, while Efimova came up just shy of a world record in the 200.

#2: Sarah Sjostrom – 50 free – 23.67

This one you could see coming for awhile, after Sjostrom rattled the mark about a month out of Worlds and then used an early 100 free world record to show she could be faster at Worlds.

Sjostrom seemed to really focus on her freestyles this time around, not breaking her own insane world records in the 50 and 100 fly races, but still dominating them by wide margins. (Let’s be honest, Sjostrom could probably win those events at Worlds without a taper and shave right now, so good on her for putting a little more focus on expanding to freestyle).

This one takes down a super-suit record that was pretty untouchable for about 8 years. Britta Steffen’s 23.87 is now gone and Sjostrom has taken down two of the four sprint free records that had at one point appeared all-but-unbreakable. (The men’s 50 and 100 free records still remain, though the 100 has come under assault).

Breaking the 24-second barrier adds some style points, as only a few others have been able to do that in textile. It’s also impressive that Sjostrom was this fast after so many previous swims, and she finishes this meet with a meet-high 3 gold medals and 2 world records individually. Only Katie Ledecky and Caeleb Dressel can match her individual win total, and only Lilly King can match her individual world record total from Budapest.

#1: Team USA – Women’s 4×100 medley relay – 3:51.55

This is an awfully impressive relay. Consider that since the suit ban, no other nation has been better than 3:53.38 in this event. Even with super-suit times included, no other nation has been faster than 3:52.19. Team USA broke an 8-year-old world record that at the time won Olympic gold by two seconds.

A splits comparison is interesting, as it shows the huge value of the American leap forward in women’s sprinting. Simone Manuel‘s anchor leg saved the team more than a full second against the old record. Lilly King was the other big shaker, swimming four tenths faster than the old recorded mark.

London 2012 Budapest 2017
Missy Franklin 58.50 58.54 Kathleen Baker
Rebecca Soni 1:04.82 1:04.48 Lilly King
Dana Vollmer 55.48 56.30 Kelsi Worrell
Allison Schmitt 53.25 52.23 Simone Manuel
3:52.05 3:51.55

That was the cherry on top of what was the most successful World Championships in history for the U.S. women, and capped a relay sweep that has only happened three times since 1986.


There isn’t a second that goes by when the team at blueseventy aren’t thinking about you. How you eat, breathe, train, play, win, lose, suffer and celebrate. How swimming is every part of what makes you tick. Aptly named because 70% of the earth is covered in water, blueseventy is a world leader in the pool and open water. Since 1993, we design, test, refine and craft products using superior materials and revolutionary details that equate to comfort, freedom from restriction and ultimately a competitive advantage in the water. This is where we thrive. There is no substitute and no way around it. We’re all for the swim.
