Women's 800m semis
BBC OneLynsey Sharp after reaching the final: "I have just been so looking forward to getting that Q next to my name. I am so happy to have done that. It didn't really go as I planned, I was in a few positions I did not plan on but the main thing was to stay patient, trust in my coach and it paid off. I live for this stuff and to get into the final is a massive relief but this is where it really starts.

Paula Radcliffe
Women's marathon world record holder on BBC TVWhat I like about Lynsey Sharp this year is she does not panic when the race gets into the closing stages. She was patient and waited for the gap to open up and when it did she struck hard and struck fast to claim that spot.

If anyone beats Caster Semenya it would be one of the shocks of these Games. She looks serene.

Women's 800m semis
Paula Radcliffe
Women's marathon world record holder on BBC TVShelayna Oskan-Clarke was in a great position but Melissa Bishop moved a little and Shelayna lost a bit of her momentum and her fight as well as she struggled to come back. She needed to keep fighting because she was just a couple of strides from fourth there.

Women's 800m semis
Caster Semenya means business tonight. She has dominated this event all season and is expected to win tonight too.
Lynsey Sharp goes for GB. A time of 1:59.40 could be enough to put her through.

Men's shot put
Ryan Crouser has won it! A superb series of putts has seen him win it. One throw to go too.
His last throw is up near 22m again, so consistent. It's 21.74m.

Where did she come from?! Joanna Jozwik piles through at the end to win that semi as Shelayna Oskan-Clarke finished fifth. She was baulked badly with 200m to go.
