The U.S. have made a single change for this relay tonight, bringing in Josh Matheny for Campbell McKean. After Tommy Janton and Dare Rose stepped up this morning with times of 53.21 on backstroke and 50.39 on fly respectively, the two have kep their place on what were looking like the two problem legs for the U.S. just 24 hours ago.

They will likely still be down on the field after the backstroke, but  that back half gives them hope to power through and get in the podium conversation by the end of the race.

That will require the U.S. to be faster than this morning however, as France, Italy and NAB all put out teams that have the capability to blow the rest of the field away. Each features a swimmer who has been 51-point on backstroke so far, and Nicolo Martinenghi (ITA) and Kirill Prigoda (NAB) are the class of the fierld on breaststroke.

Leon Marchand will swim the breaststroke leg for France, just 30 minutes after the end of the men’s 400 IM. He has taken on brutal schedules before in the NCAA, including the 400 IM to breaststroke-on-medley-relay double, and managed to still perform at his best in the latter. If he is in 58-point form for France, and Yohann Ndoye-Brouard is on his best time on backstroke, Maxime Grousset can break open the race on fly.

Italy and NAB will put out Federico Burdisso and Andrei Minakov respectively on fly, who both split 50.6 on the prelims relays, but Grousset was 49.62 in winning the 100 fly yesterday and has split 49.27 and 49.57 on this leg in the last two years. Having dropped half a second from a flat start, he could seriously challenge the 49-second barrier and Caeleb Dressel‘s 49.03 #1 all-time split.

France put Yann le Goff on free, which is their weakest leg. He has been 47.55 and 47.77 so far on relays, which may well be enough to hold off Carlos D’Ambrosio and Egor Kornev.

Canada look dangerous after Blake Tierney broke the Canadian Record on backstroke this morning, and have a wicked back half of Ilya Kharun and Josh Liendo. The U.S. may need o be wary of their North American rivals if he can replicate that time and Oliver Dawson delivers another 59-mid split after doing so when they took bronze in the mixed medley relay.

Great Britain, Netherlands and Korea all stick with the same quartets as this morning.
