Fontijn is feeling the pace a little bit here.

Fontijn is feeling the pace a little bit here.
Women's middleweight
Another good right by Marshall. Is Fontijn getting a little leggy? End of round three.
Women's middleweight
Fontijn, by the way is the number two seed. She's coming back in this third round. Marshall has to give it some thought.

Marshall responded well in that round, she boxed much better.
That is very unlucky.
Women's middleweight
Marshall only gets the nod from one of the three judges. That's unlucky.

I had no idea BMX was big in Colombia until today. They love it it seems.
Near the finish line you can hear music, then when that dies you get Colombian screams and if you listen really carefully you can hear the rattle of a bike chain as riders make that 20ft drive for the line, thrusting their bike forward to save a split second on the line. The BMX version of dipping for the line.
We are getting to the top riders now. Blink and you'll miss them.
Women's middleweight
Another cracking right to end the round. Has Marshall done enough to take that one?
Richie Woodhall
Former world champion on BBC TV
This is a much better start from Marshall. She has got to keep it going.
Women's middleweight
Better from Marshall, who is slightly shorter. Break as she has her headgear adjusted.
Women's middleweight
More accuracy from Marshall, who is finding the target more often. Jab, right hand, then to the ribs. Landing...
Richie Woodhall
Former world champion on BBC TV
I don't think that was too bad at all from Marshall. She was on the front foot.
There was not much in that round at all it could have gone either way.
Women's middleweight
The judges in this Olympic boxing competition have been more unreliable than weather forecasters. They gave the first round to Fontijn.
Women's middleweight
Untidy first round, all at close range. Positive from Marshall, though, who was on the front foot throughout.
Women's middleweight
Four two-minute rounds, fighters tied up midway through round one. It's good from Marshall, who lands an overhand right.
Women's middleweight
Marshall in red, Fontijn in blue. The Dutch fighter has won their last four meetings and won silver at the last World Championships.
Women's middleweight
But enough of that nonsense, there's business to attend to. Great Britain's Savannah Marshall is one win away from a guaranteed medal. If she beats the Netherlands' Nouchka Fontijn, she'll take bronze at least.
That's right. Aly Raisman and Simone Biles, five golds, two silvers and a bronze between them, are tucking into the fast food. It's a familiar theme, with big queues reported in the Olympic park. It wouldn't be my way of celebrating an Olympic medal. I'd be heading to the pub and not coming out for about three days. Each to their own. Let me know what you'd do.
Women's individual stroke play
No more movement from Charley Hull. The British number one, ranked 27th in the world, is still three-under par. But only just! She lips out with a birdie putt on 13.
South Korea's Inbee Park is still leading on five-under, with about half of the 60-strong field still out in the Rio sunshine.
