We actually had our expectations for the ultimate of the combined medley relay shaken up this morning. Olympic champions USA had been three-tenths exterior making the ultimate in tenth, and fellow Paris finalists Nice Britain and France joined them in failing to make the highest eight.
With China not in domineering kind and each different nation having at the least one weaker leg, the medals may realistically go to any one in all 5 or 6 international locations. The lineup selections may make an even bigger distinction to the rostrum than ever earlier than.
Flying splits from Singapore are used the place accessible. The place these usually are not, we now have used the swimmer’s greatest particular person time from Singapore with half a second taken off (*), or their season-best with half a second taken off (**).
Combined 4×100 Medley Relay
Italy – 3:42.19
There are two locks for the Italians – Thomas Ceccon on backstroke, on what’s his first day with no particular person swims, and Sara Curtis on freestyle.
The center two legs are prone to be a male breaststroker after which Constanza Cocconcelli on fly, however with Martinenghi reportedly struggling barely from sickness, it may very well be Ludovico Viberti as a substitute of the 100 breast silver medalist. In that case, the season-best distinction between a Bottazzo-Burdisso lineup and a Viberti-Cocconcelli one is simply over half a second – seemingly sufficient however not a certainty.
They did go Viberti-Cocconcelli this morning as they progressed in 1st from the heats, however neither has a swim this night they usually each had stable splits.
One thing that does tip the scales much more in favor of the latter is that Burdisso has the 200 fly ultimate tonight, his first since Tokyo in 2021. That does come in the midst of the session and an hour earlier than the relay, however the lure of fresh water at midway, and the chance to road-test the entrance half of the all of the sudden podium-threatening males’s medley relay, could also be too engaging to disregard.
With a medal on the desk, count on Ceccon to sub in for Bacico as they attempt to win their first ever medal on this occasion.
A fast word on the younger backstroker – after coming in with a better of 53.42, Bacico has now been 52.72, 52.72 and 52.68 in Singapore. That’s large for Italy’s depth and skill to relaxation Ceccon.

Netherlands – 3:42.56
The Netherlands may properly be a significant participant, though their very best lineup proper now would have Marrrit Steenbergen on each backstroke and freestyle. As that sadly will not be allowed, there are two choices for them tonight
Choice 1 can be Maaike de Waard on backstroke, with Steenbergen on the anchor leg the place she is going to hope to reprise her huge 51.64 anchor leg on Day 1 that dragged the ladies’s 4×100 free relay from eighth to bronze. The second is Steenbergen on backstroke, with 53.1 swimmer Milou van Wijk on the freestyle.
They might lean in the direction of the previous, after Steenbergen was simply 59.86 individually, properly off her better of 58.96. De Waard was really sooner than that this morning, clocking a time of 59.72 to come back inside a tenth of her greatest.
The center two legs are each locks. Caspar Corbeau, who was 59.0 in heats and the ultimate of the lads’s 100 breast, with a semi-final 59.1 in between, might be on breaststroke and break up 58.75 this morning, with Nyls Korstanje on fly.
He was 22.84 within the males’s 50 fly ultimate to take sixth, and was 51.04 on the fly leg this morning. He’ll hope to be nearer to the 50.27 he break up final summer time, and if he’s they might shake issues up.

China – 3:42.81
China has some attention-grabbing decisions to make. The truth that Xu Jiayu is in 53-low quite than 52-low kind makes their resolution of how one can break up this relay way more tough, and Qin Haiyang and Zhang Yufei on the center two legs are the one swimmers who’re locks.
With Yang Junxuan not in Singapore, placing Pan Zhanle on the anchor and Peng Xuwei on backstroke comes out barely sooner than Xu on backstroke and Wu Qingfeng on the freestyle primarily based on outcomes up to now. XU does have a season-best of 52.49, however has been solely as quick as 53.14 right here.
Xu on backstroke does give them a better ceiling, and Qin could also be greatest served with clear water quite than preventing by way of the wash. With gold now a robust risk with the U.S. failing to advance, there doesn’t appear to be a lot sense in going conservative.
That’s betting huge on Xu, who has been 53-point 3 times now in Singapore, however would permit Pan to keep away from a double. Don’t be too shocked in the event that they do go along with Peng and Pan, however apart from in 2024 after they missed the ultimate China has by no means led off with a girl on backstroke.

McKeown might be on backstroke for particular, however this workforce is sorely lacking a breaststroker. They received a 58.43 from Josh Yong en path to bronze final summer time, however Nash Wilkes was 1:00.42 on day 1 and solely just below the minute mark this morning.
His 59.76 break up might be sufficient to see him on the finals relay. Sienna Toohey and Ella Ramsay are each 1:06 swimmers, however that is nonetheless the leg the place the hole between female and male is largest.
That leaves a possible Matt Temple–Meg Harris again half, with neither having every other swims at this time. They went Perkins-Taylor this morning, making the potential of Perkins-Chalmers this night a distant one, particularly with Chalmers having the 100 free semis. That add-up is nevertheless barely sooner on paper, though Perkins was simply 56.80 this morning, off her semi-finals time of 56.19
Harris was 51.87 on the ladies’s 4×100 free relay, and though we’re but to see Temple swim right here he ought to be at the least a 50-point break up primarily based on previous performances.

Just one leg of Canada’s prelims relay is a particular return tonight, with Josh Liendo nailing down the fly leg with a swim of 49.85. Elsewhere, Kylie Masse ought to slot in for Ingrid Wilm to offer them a few second over the 59.34 Wilm swam this morning.
There’s a resolution to make on breaststroke, the place Oliver Dawson had a great swim this morning to interrupt 60 seconds and go 59.97, 0.76 seconds beneath his flat-start greatest. Finlay Knox was the breaststroker in Paris final yr, and gained’t have the 200 IM semis tonight. Nevertheless, after he was simply 1:01.02 within the individually on Day 1, Dawson has seemingly executed sufficient to maintain his spot.
Freestyle has the most important resolution. Brooklyn Douthwright was 54.31 this morning, and might be subbed off for both Mary-Sophie Harvey, Taylor Ruck or Summer time McIntosh. Who the coaches decide will define how critical they suppose their possibilities of a medal are. McIntosh does have the 200 fly semis simply 25 minutes beforehand, however has the upper ceiling. If she’s on, they’re going for broke.

Japan – 3:43.57
Japan appear to be they went with their strongest workforce this morning. They’ve two potential substitutions, neither of which initiatives to maneuver the needle an excessive amount of.
The primary of these can be to interchange Taku Taniguchi on breaststroke with Yamato Fukusawa, who does have the sooner season greatest. Nevertheless, he was a second off that individually and didn’t make the semi-finals, whereas Taniguchi did and was 59.59 for 14th general. The newly-minted 50 breast Japanese document holder ought to hold his place.
The second can be Rikako Ikee for Nagisa Ikemoto, however after she break up 53.58 this morning changing Ikemoto could not make the relay any sooner. Anticipate them to stay quite than twist.

NAB – 3:44.14
The emergence of Daria Klepikova appeared to have made this resolution a simple one for NAB, however their prelims workforce raised at the least one query.
Neither one in all Kliment Kolesnikov and Miron Lifintsev had been at their greatest within the 100 again individually, they usually ended up sixth and seventh within the ultimate. Lifintsev didn’t go beneath 52.5 by way of the three rounds, making Kolesnikov look your best option for the finals relay, however the 19-year-old then threw down a leadoff of 52.08 this morning to match his greatest time.
The query then is whether or not or not he’s left on. The coaches seemingly outlined that it could be Kolesnikov for finals no matter Lifintsev’s efficiency this morning, with the distinction between the 2 successfully a wash, however it’s one thing to keep watch over.
They need to go Kolesnikov-Prigoda-Klepikova-Trofimova tonight, returning half the swimmers (Prigoda and Klepikova) from the workforce which broke the combined medley relay document at brief course worlds.
Chikunova on breast and Minakov on fly can be the one different actual possibility, however Minakov didn’t look nice within the 100 free heats this morning. That might permit Klepikova to slip to free, the place she was 52.68 anchoring the ladies’s 4×100 free relay on Day 1.

Poland will virtually actually run it again tonight. Adela Piskorska was 1:00.72 within the 100 again heats, whereas Ksawery Masiuk was 52.67 within the semi-finals for the lads. With no feminine top-tier flyer, Jakub Majerski‘s spot on fly ought to be safe as properly.
That signifies that they are going to go M-F-M-F, seemingly the one one within the ultimate to take action and the one one of many eight finalists to take action within the heats. Dominika Sztandera will return on breaststroke, as will Kasia Wasick on freestyle.
