Men's 100m semi-finals
The first two men in each of the three semi-finals go through to the 100m final. So spare a thought for GB's Chijindu Ujah tonight.
He is in the same semi as Trayvon Bromell - the second fastest man in the world this year - and a certain Usain Bolt.
Fastest loser?
He goes away at 01:07 BST.

Only two go through and Christine Ohuruogu is fifth. Her run is over.
The race was won by Phyllis Francis in 50.31, with Stephenie McPherson taking the other slot.
Francis looked very, very, very good.
Murray 7-5 4-6 6-2 4-5 Del Potro*
Those few Brits in the Centre Court crowd look a bit tense. Not surprising when there are a few thousand Argentines trying to intimidate their man Murray. Trying being the key word. He holds his nerve and holds his serve. If Delpo fancies raving a little later tonight then he will have to do it on his own terms.

Christine Ohuruogu is perhaps fourth or fifth at 200m...

Silence please. Then the gun! Bang! Away they go...
Women's 400m semis
First semi in the blocks, Christine Ohuruogu out in lane seven. Tough.
Only the top two in each semi go through to the final, plus the two fastest losers.
She looks calm, happy, smiling.
*Murray 7-5 4-6 6-2 3-5 Del Potro
Del Potro has been superb with the ball in hand tonight, sticking 73% of his first serves into play. A brief wobble lets Murray back in at 0-30, but the Argentine steadies himself to rattle off four straight points. Big hold. Big chance to take this into a fifth. A break here will do the trick...

Suping Meng has just become the strongest woman at these Rio Olympic games, which also means that China leapfrog team GB in the medal table once more.
Over to you, Mr Murray.

Image source, .The ball boys/girls here have been given an unfortunate outfit in my book. Green shirts, khaki shorts, they look like they'd make fine park rangers.
You have to admire their chilled nature though. There's none of this straight arm ball release like Wimbledon. They lob it any way they want.
Their night could get longer as Juan Martin del Potro breaks, his smash to go 4-3 up brings the house down.
Murray v Del Potro
Russell Fuller
BBC tennis correspondent in Belgrade
I really didn’t think we would witness this match going to a deciding set.
Murray 7-5 4-6 6-2 3-4 Del Potro*
Del Potro has a sniff of a break. Murray lets some steam out with a bout of tennis tourettes at 30-15. It doesn't work. The Briton slams a routine forehand into the tape - two break points Delpo...
He only needs one! Muzza is dragged out wide, knocks up a weak lob, Delpo smashes into the green acrylic. No chance for Murray, who almost takes out the line judge as he bounds after the ball like a golden retriever. The boisterous Argentine-dominated crowd break out into an "Ole, ole ole, ole, ole..."

Women's 400m semi-finals
Christine Ohuruogu won the 400m in 2008 and won silver in 2012.
Can she first make the final tonight, and then trouble the medals again?
Murray v Del Potro
Mary Pierce
Former French Open champion on BBC Radio 5 live
It’s quite disheartening for Del Potro because, the state that he’s in physically, if you don’t take the opportunities that you do get, you know against someone like Andy Murray you’re not going to get too many.
Rutherford gets bronze
The first action in the stadium tonight sees Greg Rutherford handed his bronze medal for last night's long jump.
If you missed that final - please watch it back. It was absolutely epic. Sensational. Every jump was a twist and a turn.
*Murray 7-5 4-6 6-2 3-3 Del Potro
Not sure what else Del Potro was given by his physio - but it has worked. He continues to step up from the baseline, thumping a quartet of balls past the stretching Murray. Love service game, crowd getting lively. It is like a Davis Cup atmosphere down there. Or a Boca Juniors home game.
Women's 400m semis
GB's ultimate 'tournament' racer?
Christine Ohuruogu is rarely well-fancied going into the 400m of any event, she is often off form, carrying an injury, struggling for speed - but when it counts, she puts it together,
The 32-year-old has won gold and silver in the last two Olympic Games, and has two world titles in her collection too.
She goes in the first semi-final at 00:35 BST.
Emily Diamond, also of GB, goes in the second semi.
