Only James Guy booked a ticket tonight, so we have 19 guaranteed athletes.
Luke Greenbank is also now on priority 5 with his 200m Backstroke. Let's say those 4 will be included and we would have a team of 23 (except Tobias Robinson).
They could easily say "we're done" but it would be a bit odd I guess. I still believe they will take both relays, or at least ask them to do a tryout. If they decide to take 30, those are my bet for the 7 extra, kind-of-on-order
I think there are 4 safer bets because either they won their races, or they would form relays
Kieran Bird - M 400m Freestyle (OQT), not only he has an OQT and won the event, he could be a relay option, with his 6th on 4x200m Freestyle
Angharad Evans W 100m Breaststroke (OQT), not only she won but she could form the 4x100m medley
Eva Okaro - W 4x100m Freestyle (2nd- relay not qualified)
Freya Anderson - W 4x100m Freestyle (3rd- relay not qualified) she could easily compete at W 100m Freestyle, W 200m Freestyle and she was injured
Then I guess they could take these 3 to be options for relays, and 2 of them are big names
James Wilby - M 100m Breaststroke (he could even participate in the individual with his OQT and would be a back-up for 4x100m medley)
Jacob Whittle - M 4x100m 5th Swimmer?
Jack McMillan - M 400m Freestyle (OQT), and he also would be a great option to swim in the heats for 4x200m Freestyle
