The U.S. men wrapped up a blistering opening day of racing at the 2024 Short Course World Championships with a bang on Tuesday, obliterating the world record in the 4×100 freestyle relay.

Jack Alexy was electric on the lead-off leg, clocking 45.05 to break the American and World Championship Record in the 100 free, and he was followed by Luke Hobson (45.18), Kieran Smith (46.01) and Chris Guiliano (45.42) as they ran away with the world title by two seconds.

The U.S. team clocked in at 3:01.66, knocking more than a second off the previous world record of 3:02.75 set by the Italians at the 2022 SC World Championships.

As an anchor, Giuliano should have the fastest split. He is a bit off.

These guys must have missed the “US Men’s roster is weak” memo. Props to them for a big time swim that will surely give momentum to the team for the rest of the meet

Where was Matt King?

Yea I was wondering the same thing. Not to downplay Kieran at all but the 100 isn’t usually a primary event for him, and I imagine king could’ve split another 45-mid or 45-low which could’ve dropped that time sub-3:01. Hopefully he’s not sick.

Kieran has historically been a great short course relay guy. He’s put in competitive SC 100 and 50 relay splits at other SCWs and in the NCAAs so I guess they just trusted him

Yes, Matt King was sick and replaced for this relay. Matt, Take care and hope to hear you are back in the pool soon.

I guess the coaches didn’t believe in those 19.2 push 50 splits.
