Yet another surprise on the cards?

We are minutes away

All eight athletes are in the call room.

Less than ten minutes to go

We'll be starting with the women's 200m Freestyle semifinals. 

In the first semifinal, we'll see Ariarne Titmus, who won gold in 400m freestyle yesterday and there's also Allison Schmitt who has the current OR in the event.    

OLYMPIC RECORD TO BE BROKEN AGAIN?

The Olympic Record in the women's 100m Backstroke event has already been broken four times at the Tokyo Olympics and it is currently with United States' Regan Smith at 57.86s.

Kaylee Mckeown would be looking to break it a fifth time and the battle between the teenagers is the one we've been waiting to see for a while. 

WELCOME

I hope you're up and ready as it's Day 4 and we're all set for what could be yet any other day for new records to be set.

Live-action to start in 25 minutes. Stay tuned.
