Tears for Murray. Tears for Del Potro. But not after the Argentine grabs hold of his opponent at the net in a loving bear-hug. There isn't a dry eye in the house...
Men's 100m semis
Usain Bolt looks super focused here. I'm expecting a good time...
Men's 100m semis
HUGE roar for Usain Bolt. What a legend.
Men's 100m semis
CJ Ujah of GB goes in this second semi-final, alongside Usain Bolt and Trayvon Bromell.
Good luck.
Kim Collins is running! At the age of 40. Insane.
Murray 7-5 4-6 6-2 7-5 Del Potro
He's done it! Murray wins gold. Britain win gold.
Muzza has a second chance in deuce, luring Del Potro into a baseline duel, before springing forward and leaving Delpo rocking. The Argentine buckles, slaps into the tape and it is all over.
Double Olympic gold for Andy Murray!

Men's 100m semis
Usain Bolt in the starting blocks, a choreographed routine of checks and balances as they fiddle with the apparatus. A few practice starts, he looks mean and lean.
Murray 7-5 4-6 6-2 6-5 Del Potro*
Game on after that brief interruption. And Del Potro loses focus!
Murray has match point. AKA gold medal point.
But he blows it! Deuce...

Busiest night by far in Estadio Olimpico. Is it completely full? No. But lots of green, black and gold to support the reigning 100m champ, samba drums pounding, and a warmth that hasn't been there in the Rio air before this night. A recipe for fast-twitch and low times.
Men's 100m semis
Away first time! Hushed stadium, coiled springs.
Jimmy Vicaud powers through to win in 9.95, good run. Ben Meite sets a national record for Ivory Coast to take second in 9.97.
Akani Simbine clocks 9.98 in third and will have to wait and see...
Murray 7-5 4-6 6-2 6-5 Del Potro*
Chances of Murray breaking Del Potro's serve? He's already done it three times. In this set.
The Argentine lands the first blow, Murray responds with one of his own. They exchange points again...30-30.
Murray smells blood. A shout from the crowd puts him off as the Wimbledon champ bashes a forehand into the net. Focus Andy. That he does, winning the next point.
Deuce. But only after an animated Argentine is turfed out for being too loud...
Men's 100m semis
Steve Cram says that Ivory Coast runner Ben Meite is the man to watch out of the blocks. Fast starter. Let's see.
Men's singles final
Great stuff from both Murray and Del Potro! Take a look at the unbelievable rally between the two in the men's singles final.

Olympic heptathlon gold medallist on BBC Four
We feel Usain Bolt is in good form and that Justin Gatlin doesn't stand much of a chance this year so we're feeling a lot more comfortable about this head to head than last year.
Men's 100m semis
Six of the eight men running in this first 100m semi have dipped under the 10-second barrier this season.
What sort of time will we see here? Only the top two through by right. Got to be looking at 9.9 or quicker for me...

This is what it's all about I guess. A men's Olympic final of superb quality goes on and on as the fastest man on earth gets ready to roll again some 20 miles away.
Greatness sprawls across sprawling Rio. A proper Olympic night. If you've stayed up, it's all you deserve.
Murray 7-5 4-6 6-2 6-5 Del Potro*
Wow, wow, wow. These two are digging so deep they will be hitting the outer core of Earth within half an hour - presuming we go that far.
Del Potro tees up two more break points, but Murray isn't going to roll over. Oh no, he replies with a howitzer of an ace to force deuce, then instantly follows it up with another.
He seals the deal, leaving him one break away from his second Olympic title.
