Watch: Grevers-King-Dressel-Manuel Crush WR in Mixed Medley Relay (Race Video)


Twice in one day, Team USA produced the fastest quartet in history in the 4×100 medley relay. But the second time it was a different foursome. After Ryan Murphy, Kevin Cordes, Kelsi Worrell and Mallory Comerford (3:40.28) took nearly a 1.5-second chunk out of Great Britain’s 2015 mark in prelims, USA fielded the combination of Matt Grevers, Lilly King, Caeleb Dressel, and Simone Manuel in finals. This group absolutely crushed the hours-old world mark, touching in 3:38.56.

  • World Record: USA, 3:40.29, 2017
  • Championship Record: USA, 3:40.29, 2017
  • Junior World Record: Russia, 3:45.85, 2015
  1. USA 3:38.56
  2. Australia 3:41.21
  3. Canada/China 3:41.25

Team USA dominated the field, putting together a 3:38.56 to take almost two seconds off of their world record from prelims, which had four completely separate swimmers. All four legs swam very well for the Americans, but it was Caeleb Dressel who unleashed a 49.92 split on the butterfly leg, the real difference maker for them. That’s an incredibly fast swim, and it’s nearly a full second better than his lifetime best.

Matt Grevers led off in 52.32, faster than his silver medal time, with Lilly King following in 1:04.15. Remarkably, she held her ground despite being the only female breaststroke leg in the field. Dressel gave way to Simone Manuel, who put together a 52.17, nearly an identical split to what she did on the end of the women’s gold medal 4×100 free relay.

The race for silver was a scramble, with Australia just getting ahead at 3:41.21. They had a nice 52.30 anchor leg from Bronte Campbell. Canada and China ended up tying for the bronze, and both teams had some impressive legs. Canada was led off by Kylie Masse at 58.22, another great time from her, and Penny Oleksiak put together a very strong 56.18 fly split, with Yuri Kisil anchoring in 47.71. Xu Jiayu led off in 52.37 for China, with Yan Zibei dropping a 58.98 on the breast.

GBR was out of medal range at 5th, though they were just tenths back at 3:41.56. They had a fantastic middle grouping with Adam Peaty (57.12) and James Guy (50.51), but the rest of their relay wasn’t strong enough to push them to a medal.

This relay would have beaten the US men’s team at the 1984 Olympics. Rick Carey/Steve Lundquist/Pablo Morales/Rowdy Gaines went a 3:39.30 which was a new world record at the time.

Great observation . It also took only 17 years for a single man to almost get that in 3.40. – thats only 3/4 of a generation . I should check the girls – it would be 1/2 a generation .

Technical improvements – pools depth & 10 lanes & u/water lighting / compression swimwear / hydrodynamic caps / goggles design & expanded vision / back start wedges & turns /breast head submergeable / breast dolphin kick .

Rowdy gets out-touched because he’s breathing to his right and can’t see Manuel

Why does everyone hate on this event? That was so much fun to watch. Swimming never gets crazy like that!
