Greatest Tests: Perera's Durban miracle or debutant Cummins' Johannesburg heroics?

Sri Lanka were enduring a tough time heading into this series. They were coming off a 2-0 pummeling in Australia, their captain had been sacked, and an inexperienced team, led by Dimuth Karunaratne, was put on the plane to South Africa. The perfect lead-up to a heroic comeback story?

In what was a seesawing Test in Durban, Sri Lanka emerged victorious, chasing down 304 with one wicket to spare. They had lost their ninth wicket while still 78 runs off their target. Kusal Perera then scored 67 of them all by himself. Perera gave Sri Lanka an incredible finale on the fourth afternoon along with the No. 11 Vishwa Fernando, as they put on a record-breaking tenth-wicket stand to see their team home in a tense finish.

At lunch on the day, Sri Lanka were 166 for 5, still 138 runs away from a win, after which Keshav Maharaj scythed through the Sri Lankan lower-middle order, leaving them at 226 for 9. That brought Fernando to the middle, and from the moment he got there, he was entirely focused on survival. He faced 22 balls before he got off the mark.

It looked like victory was assured for South Africa, but as Fernando clung on at one end, Perera defended with unreal calm and even took several blows to his body on his way to the target. Batting for 309 minutes, he farmed the strike superbly, and picked his opportunities to attack and push the score forward. Along the way, he also made his career-best Test score of 153, sealing the famous win with a boundary.

Trust Pat Cummins to do something heroic. But to do such a thing on his Test debut? As an 18-year-old?

Australia had a lot to prove entering this Test. They had been bowled out for 47 in the first Test of the series in Cape Town, their lowest total in 109 years. They had lost that match before lunch on the third day.

In seaming conditions at the Wanderers, Australia took a 30-run lead in reply to South Africa's 266. Having been brought in as Ryan Harris' replacement for the second Test in Johannesburg, Cummins came to Australia's rescue in the second innings as he outbowled his more senior colleagues.

He gave Australia a fighting chance of victory in a match that, 24 hours earlier, appeared to have slipped from their grasp after superb batting from Hashim Amla and AB de Villiers. Cummins was responsible for breaking the Amla-de Villiers stand, as he went on to bag six wickets to set up a target of 310 runs for his team.

Openers Shane Watson and Phil Hughes failed to repeat their first-innings displays. They were both out to Vernon Philander as Australia were 19 for 2, but Ricky Ponting and Usman Khawaja brought down the home side's advantage. Morne Morkel and Dale Steyn's strikes, though, left Australia six down with another 95 runs to get.

Brad Haddin and Mitchell Johnson then forged a partnership of 72 to erase the bulk of the deficit, but with his team eight down with 12 runs required, it was Cummins who kept his calm and scored two boundaries in the 15 balls he faced to seal the close win for Australia. It was the highest fourth-innings total at the Wanderers.
