This is Kumar Sangakkara and Mahela Jayawardene's 150th ODI partnership. Only India's Sachin Tendulkar and Sourav Ganguly have more - 176.

'Sangawardene' have played a combined 850 ODIs, scoring 16,835 runs between them and 5,890 runs while at the crease together - again second only to Tendulkar and Ganguly.

Sangakkara and Jayawardene will both retire from ODIs after this tournament. Will today be the last we see of them...?

"It was quite a tame shot. I'd need a replay to see if it was a wrong 'un - Thirimanne got the innings going. Warm applause for Jayawardene coming out - is the last time we'll ever see these two batting together in an international?"

He scored 41 off 48 balls, but Lahiru Thirimanne is trudging off. Tahir's delivery looks to stop on the batsman, who is early on the shot and can only prod it back from where it came. Tahir holds on to the chance and Sri Lanka are three down.

Imran Tahir concedes six off the over, but has his hands on his head as Thirimanne edges one. But there is no slip and the batsman surivives. It would have been a simple catch if someone was there. Sangakkara 12. Off 49. Yes, you read that correctly.

Only 222 from Steven Finn. If only! Melbourne is the setting for the second quarter-final between India and Bangladesh tomorrow.

Not much to get excited about in the 17th over. Three singles come from it. Sri Lanka need to put their foot on the accelerator, and need to do it soon. We have already seen South Africa reach 400 twice in this World Cup. They are not going to be chasing a target anywhere near that if this pace continues.

"Not a bad first over from Imran Tahir, he beat the edge, which with Sangakkara batting is no mean feat. He's been very watchful in the face of some very good bowling from the South Africans."

So it is now spin at both ends. JP Duminy at one end, and Imran Tahir at the other. Tahir has already taken 11 wickets in this World Cup, including figures of 5-45 and 3-36 against West Indies and Zimbabwe respectively.

Sangakkara, with six off 42 balls, is lucky to survive as Tahir beats his outside edge. Sangakkara then says 'enough is enough' and scores his first boundary, sweeping over square leg. The partnership between these two is now 51, after Sri Lanka had been 4-2.

"The 'World Cup' should be just that - hopefully there will be an edict for the top teams play the likes of Afghanistan more often. I quite like this World Cup the way it has panned out, the skills have been very impressive. Maybe there could be a few more double-headers in the first week to 10 days just to tighten up the duration."

"Some excellent insights offered in the TMS box - explanations as to how the cover fielders are getting tight in order to squeeze the batsmen and questioning the curious nature of Kumar Sangakkara's knock. The conclusion? Even when you've got four hundreds behind you, knowing it could be your last knock will make anyone nervous."

And it is JP Duminy who is given a chance. He has bowled in all four of the matches he has played, but has only taken two wickets, with one of those coming against United Arab Emirates. A man to target? Maybe, but not yet. Only three singles off the over, two from Thirimanne and one for Sangakkara, who now has a tortoise-like six off 40 balls. Drinks time.

Kumar: Odds are heavily stacked against SA. Lost the toss, fifth bowler will be slaughtered by the batsmen not under pressure. Fifth bowler will go for 100 plus.

"South Africa have four real frontline bowlers plus Duminy as the fifth. I watched De Villiers bowl in Auckland the other day and it was pretty basic."

We are getting to the stage where AB de Villiers may be looking to throw the ball to someone else. But where is he going to turn to? Rilee Rossouw? Himself? Sri Lanka may well be looking to target the back-up bowlers when they come on. A tight over from Kyle Abbott with only run coming off it.

"Sangakkara is definitely on the top shelf of batsmen in Test and one-day cricket. They may have to make another shelf for Tendulkar, Sangakkara, Lara and Ponting. I've never seen anyone quite like Lara, but Viv Richards was probably my favourite of all time."

Four byes off Morne Morkel's bowling. Sangakkara remains on five. He has faced 34 deliveries. But he still remains the danger man.

"Sangakkara is the sixth man to score 500 runs in a World Cup, after Sachin Tendulkar (673 in 2003 and 523 in 1996), Matthew Hayden (659 in 2007), Mahela Jayawardene (548 in 2007), Ricky Ponting (539 in 2007) and Tillakaratne Dilshan (500 in 2011)."

What a tournament it has been for Kumar Sangakkara. He moves on to 500 runs for the competition after he finds a gap to the right of mid-off and scores three. The next highest run scorer in the 2015 World Cup is Zimbabwe's Brendan Taylor on 433.

Sangakkara is only the sixth man to make a total of 500 runs in a World Cup. India legend Sachin Tendulkar is the only man that has done it in two tournaments.

"At the back of the commentary box, an Indian journalist asked me to take a picture of him and Brian Lara. Slightly starstruck (by Lara, not the journalist), it took a while for me to work the camera phone. When I'd done my bit, Brian Charles was quickly off. I might have annoyed him."
