The men’s 4×100 free relay prelims line-ups show that the Neutral Athletes B team are front loading their team as the swim in the first of three and non-circle seeded heats as the lead off with Kliment Kolesnikov and Vladislav Grinev.

Top seeded in heat two, the Australians look to be bringing in the big guns as Flynn Southam leads off and Kyle Chalmers is set to anchor, setting up a very enticing match-up against China’s Pan Zhanle. Pan, the individual WR is set to anchor for the Chinese one lane over from the Australians.

The last heat has the Olympic Champions from the United States anchoring with Patrick Sammon. Sammon placed 2nd at Trials in the 100, a spot that normally would allow him a rest from prelims duties. Chris Guiliano is absent from the prelims relay, which may signal that he is resting for tonight or was one of the swimmers affected by the sickness that was spreading at Team USA’s training camp.
