This year he's made 1431 test runs at 79.5, including a maiden triple century, another double ton, two single centuries and eight half centuries in 19 innings.
Throw in 1256 ODI runs this year, a record, and you get a sense of the run machine he has been for his country.
In the just-concluded seven-game ODI series with England, Sangakkara ran up 2, 67 not out, 63, 86, 91, 112 and 33 - 454 runs at 75.
That time is coming up for Sangakkara - who made the Sri Lankan side in 2000 when a 22-year-old law student - is not in doubt. His great friend and fellow Sri Lankan bulwark Mahela Jayawardene has retired from test cricket and the World Cup will be the swansong for one of the true batting artists.
Sangakkara is expected to pack in the 50-over game after the cup, but has indicated he'll carry on a while in the test side. Losing their No 3 and 4 batsmen within five minutes would leave a giant hole.
Off the field, among his many credits was receiving a standing ovation - the first since Bishop Desmond Tutu six years ago - at the end of his Cowdrey Lecture on the Spirit of Cricket at Lord's this year.
During that speech, he recalled the terrorist attack on Sri Lanka's team bus in Lahore in 2009, when he was struck by a bullet, and which led to the abandoning of all international cricket in Pakistan since.
"[Team mate] Tharanga Paranavithana, on his debut tour, is also next to me. He stands up, bullets flying all around him, shouting 'I have been hit' as he holds his blood-soaked chest. He collapsed on to his seat, apparently unconscious.
"I see him and I think: 'Oh my God, you were out first ball, run out the next innings and now you have been shot. What a terrible first tour.' It is strange how clear your thinking is."
That he's a smart operator is beyond dispute. Unafraid to throw verbal jibes from behind the stumps, particularly in his earlier years, he has figured in some of cricket's more remarkable events.
Perhaps none more so than his world record 624-run stand with his great mate Jayawardene (Sangakkara 287, Jayawardene 374) to set up an innings win over South Africa in Colombo in 2006.
And you'll go a long way to see a better innings than his defiant 192 against Australia in Hobart in 2007 in a losing cause.
By curious twist, Brian Lara, Tendulkar and Sangakkara share top spot in getting to 10,000 test runs in identical time, their 195th innings. However Sangakkara was five innings faster than Lara to 11,000, 15 better than Tendulkar.
Sangakkara and Jayawardene walked a final lap on home soil together to resounding, heartfelt applause in Colombo this week after the last ODI against England.
They own a restaurant together, the Ministry of Crab.
They'll be in harness for the seven ODIs against New Zealand.
Take the time to go and watch both of them. And if Sri Lanka are to justify the suspicion that they may be decent cup contenders, they'll need them once more to deliver.
After all they've spent their careers doing just that for their country.
