USA the top seed into the finals as the only team under 3:30, China failing to advance despite swimming Qin Haiyang and Pan Zhanle in the heats, and Chalmers fading for Australia as they ended up outside the finals places as well.
There are some teams with big lineup decisions tonight, and some who will now have cemented the quartet they will use.
USA- 3:29.65
The big call in heats was to put Dare Rose onto the fly leg after he did not make the team in the individual 100, and the U.S. coaching staff absolutely nailed this one. Rose was 50.39, the second-fastest split in the field, and with the struggles of Shaine Casas and Thomas Heilman in the individual 100 fly, where both missed the semi-finals, should be guaranteed a spot tonight.
Jack Alexy is the other nailed-on swimmer, and he split 46.73 this morning as he never had to hit top gear. The pair of recent Cal graduates should be the fastest back half in the field tonight.
Tommy Janton was 53.21 leading off, 0.66 seconds faster than he was individually, and unless the coaches have seen something slightly bonkers from another swimmer over the last couple of days he should also be on tonight. That will be around a second behind the front-runners, but no one else here for the U.S. can be counted on to deliver a 53-low.
Campbell McKean may be the only swimmer to make way, although that is dependent on whether Josh Matheny is fully fit. The 18-year-old was 59.32 this morning, just off the 59.07 he split on the mixed medley.
This relay looks in far better shape now thanks to both Rose and Janton and a medal now looks a possibility, especially with China missing the final.
NAB – 3:30.05
NAB will swap out almost their entire relay tonight. Kliment Kolesnikov will make way for Miron Lifintsev, as he has the 50 backstroke final and was only 53.02 this morning. Ivan Kozhakin had a very solid 58.72 breaststroke split, but NAB can gain a second from throwing on Kirill Prigoda and a potential 57-point.
Andrei Minakov will remain on fly as the only swimmer to keep his place, and another 50-mid should be enough to give Egor Kornev the opportunity to bring the team home for gold. After Lifintsev went 51.78 for the mixed medley relay on backstroke this lineup had been all but confirmed, and nothing changed this morning. Ivan Girev going a fair bit slower than his 47.0 split from last night’s mixed medley relay makes the anchor decision an easy one as well.
Italy – 3:30.40
Italy missed the final in 2023 and 2024, but made it back comfortably tonight as they got four solid-to-great splits. The big one for tonight was Federico Burdisso‘s 50.69, nearly matching his best split from the 2022 world-title-winning relay.
That means that their fastest lineup will be for Thomas Ceccon to slide onto backstroke rather than fly. Christian Bacico going 53-point for the first time this meet makes the decision an easier one too, especially with Ceccon not necessarily faster than Burdisso’s split tonight after he added seven-tenths to his 50.42 national record in the 100 fly in last night’s final.
Nicolo Martinenghi will come onto breaststroke as long as he is fully fit, although Viberti has now split 58.65 and 58.67 here and is an elite leg if he remains. Carlos D’Ambrosio will also come onto the free leg, and was 47.34 on the mixed free relay yesterday. This team may have the best chance of any to challenge NAB for gold.
Canada – 3:30.86
Canada were the huge surprise this morning, getting a fantastic 52.95 Canadian Record on the leadoff from Blake Tierney and a 49.98 split from Ilya Kharun. They will hope Oliver Dawson dips back under the minute mark on breaststroke after posting 1:00.18 this morning, off the 59.63 he went on the mixed medley, and will bring in Josh Liendo on freestyle for Ruslan Gaziev, who split 47.75.
Tierney looks in phenomenal form here, having taken 4th in the 200 back, and hacked half a second off his best from last summer here. This relay will probably be slightly outside the medals, but after setting a National Record this morning can dip under the 3:30 barrier tonight. Kharun-Liendo on the back end already looked fantastic prior to the championships, and a likely 50-flat/47-flat will keep them in the hunt.
Netherlands – 3:31.07
The Dutch got a huge and surprising anchor leg from Sean Niewold, who has a flat start best of 48.34 but split 47.47 here. That helped put the Netherlands through to the final in 5th and clip their National Record by 0.16 seconds, and they have room to drop even further tonight.
Kai van Westering went below 54 seconds for the first time in Singapore in 53.89, but his National record stands even faster at 53.51. Caspar Corbeau‘s 58.60 was four-tenths under his flat start best and is his fastest split ever, but Nyls Korstanje on fly can be much quicker than his 51.11 from this morning.
He has a season best of 50.84 and a lifetime best from last year of 50.59. He has looked off in the 100, not breaking 51 seconds through two relay splits now and missing the individual semi-finals, but if he’s anywhere near his 50.27 split from the Paris medley relay heats, they could break this record again.
They should keep the quartet from prelims through to finals, with Renzo Tjon-A-Joe the only potential swap on the freestyle. He split 47.87 in the mixed free relay last night, but with a 21.84 first 50, and in any case was slower than Niewold’s split this morning.
Great Britain – 3:31.75
Great Britain would have feared the worst after finishing 3rd in their semi-final, but a slower than expected final heat meant they qualified for the final with room to spare. They were at full strength this morning, with the only real change to be considered on the anchor leg where Duncan Scott could be used after his heroics on the 4×200 free relay.
That probably does not give them much more than Richards could though, with both likely to be 47-low, and as Richards made the individual 100 free final after going 47.59 in the semis, he should be first choice here.
They should get some improvements from the front half, with Oliver Morgan just 52.90 and Greg Butler not breaking 60 seconds in 1:00.09. Both can knock off about half a second, with Morgan having gone 52.37 individually and Butler going 59.53 in the 100 breast semi-finals.
Ed Mildred was 51.05 on his split, three tenths under his flat-start best and quicker than Scott was on this relay last summer.
France – 3:32.35
France were another nation who would have watched the heats through their fingers, as they relied on a big 47.11 anchor from Maxime Grousset to squeak through in 7th. They had the slowest front half of any finals qualifier, with Yohann Ndoye-Brouard just 53.41 after going 51.92 individually and Jeremie Delbois adding a second to his mixed medley split to go 1:00.92.
Clement Secchi was 50.91 on the fly, quicker than his flat start best of 51.06, but this relay still looks faster with Grousset on fly and a 47-point on free. Yann le Goff has been 47.55 and 47.77 so far and looks the best option for that leg.
Grousset, who was 49.27 in 2023 after going 50.16 individually, could go 49-low again after his European record of 49.62 to win the 100 fly. Secchi would do well to come within 1.5 seconds of that, while le Goff is well within a second of a likely Grousset split.
The biggest question for France comes on breaststroke. Yohann Ndoye-Brouard will drop a chunk of time on the leadoff and they’ll find a second or so more on the back half after Grousset is switched back to fly, but whether or not this relay is a gold medal contender depends on whether Leon Marchand swims.
He has the 400 IM final tonight, which finishes just half an hour before the start of this relay. That is a very short turnaround to then go for an all-out 100m sprint, but even a fatigued Marchand could be 59-mid and better than any other option. They should use him.
Korea – 3:32.54
Korea were the beneficiaries of China and Australia’s pedestrian swims, as they snuck into the final by just 0.15 seconds. They were at full strength this morning, and if they can drop time it will most likely be due to Hwang Sunwoo on the anchor leg, where he was just 48.24 this morning.
He was 47.94 in the individual 100 free and has a best of 47.56. If he can go 47-mid and the rest of the relay replicates their swims, they can break 3:32 and set a new National Record.
Kim Youngbeom‘s 51.12 was a very good split for the youngster, but Dongyeol Choi may have a lot of waves to fight through on the breaststroke leg with Juho Lee one of only three backstroke legs likely to be above 53 seconds after going 53.60 this morning.
