Decision Review System The series was played without the players having access to the Umpire Decision Review System (DRS). At the time, the DRS could be used in any series at the agreement of all participating cricket boards, but the Board of Control for Cricket in India opposed its use in this series. Umpires could still initiate reviews to the third umpire for run out, stumping and no ball decisions.

Points table

Points System:Commonwealth Bank Series 2011/12 Table

In the event of teams finishing on equal points, the right to play in the final match or series was determined as follows: The team with the highest number of wins If still equal, the team with the highest number of wins over the other team(s) who are equal on points and have the same number of wins If still equal, the team with the highest number of bonus points If still equal, the team with the highest net run rate

In a match declared as no result, run rate is not applicable.

Won (W): 4 Lost (L): 0 No Result (NR): 2 Tie (T): 2 Bonus Points (BP): 1 (The team that achieves a run rate of 1.25 times that of the opposition shall be awarded one bonus point. A team's run rate will be calculated by reference to the runs scored in an innings divided by the number of overs faced)

Net run rate (NRR): Runs per over scored less runs per over conceded, adjusting team batting first to overs of team batting second in rain rule matches, adjusting to team's full allocation if all out, and ignoring no result matches.

Group stage matches

1st match

India won the toss and elected to field in windy conditions, and with rain forecast to interrupt the Australian innings. The rain came after 11 overs, with Australia struggling at 35–2, with Vinay Kumar dismissing both Warner (6) and Ponting (2) for single figures, and keeping the run rate tight. The rain delay reduced the match to 32 overs per side. Following the rain, Australia accelerated, and added 181 runs in 21 overs, Matthew Wade (67) making a half-century on debut, and Michael and David Hussey (45 off 32 balls and 61 off 30 balls respectively) contributing with aggressive middle order batting, to take the total to 5/216. After applying the Duckworth-Lewis method, there was no change to the target, with India to chase 217 to win.

India lost Tendulkar (2) and Gambhir (5) inside the first four overs, with Mitchell Starc (2/33) taking both wickets. Virat Kohli (31) and Rohit Sharma (21) added 51 for the third wicket, before Clint McKay (4/20) dismissed both in the 12th over, reducing India to 4/65. Wickets fell regularly, and India could not keep up with the required run rate. Eventually, India was dismissed for 151 in the 30th over. Australia won by 65 runs and claimed a bonus point; Matthew Wade was man of the match.

2nd match

Sri Lanka won the toss and chose to bat. After reaching a comfortable position at 2/100 in the 24th over, the Indian bowlers were able to stifle the Sri Lankan run rate through the middle portion of the innings with tight bowling and regular wickets. Sri Lanka passed 200 in the 46th over, and finished at 8/233. Ravichandran Ashwin (3/32 from 10 overs) was the best of the bowlers, and Dinesh Chandimal (64) top-scored for Sri Lanka.

India had the run rate well under control in its innings, and had reached 3/157 after 32 overs, before a middle order collapse saw them fall to 6/181 after 36 overs, giving Sri Lanka a chance at bowling India out. However, the number seven and eight batsmen, Ravindra Jadeja (24*) and Ravichandran Ashwin (30*), put on an unbeaten 53 run partnership to guide India to victory in the 47th over.

3rd match

Sri Lanka won the toss and sent Australia in, and dismissed the Australian top order cheaply, reducing them to 3/50 in the 9th over. Michael Clarke (57) tried to anchor the Australian innings, but wickets continued to fall around him; when Clarke fell in the 41st over, the score was 7/190, and Australia was at risk of not batting out its overs. A 32-run partnership for the ninth wicket between Clint McKay (25) and Mitchell Starc (14) helped Australia to reach the 50th over, and they were ultimately bowled out for 231 with five balls remaining. The wickets were shared, with no bowler taking more than two.

In its chase, Sri Lanka had the run rate under control for most of the innings, but lost wickets regularly. They fell to 3/88 in the 21st over, then to 6/130 in the 31st over. Batting at number seven, Angelo Mathews (64) anchored the batting in the lower order, sharing good partnerships with the tail – including 32 runs for the eighth wicket with Sachithra Senanayake and 46 runs for the tenth wicket with Dhammika Prasad – to get Sri Lanka into the 50th over, but the run rate suffered. In the end, Sri Lanka needed 18 from the last over; Mathews hit a four and a six from the first two deliveries, but was caught in the deep on the penultimate ball, with Sri Lanka five runs short of Australia's total. As in the Australian innings, the wickets were shared, with no bowler taking more than two wickets; Xavier Doherty's 2/24 from ten overs were the most economical figures.

4th match

Australia won the toss and chose to bat, and lost both openers inside the first ten overs. Michael Clarke (38), David Hussey (72) and debutant Peter Forrest (66) batted comfortably through the middle of the innings to take Australia to 4/212 after 40 overs; however, Indian fast bowlers Zaheer Khan and Vinay Kumar prevented Australia from accelerating through the final ten overs, and Australia finished at 8/269.

India batted its way into a very comfortable position at the start of its run chase, reaching 2/166 in the 32nd over to be in a strong position to win. They lost Rohit Sharma (33) and Gautam Gambhir (92) in quick succession, and the run rate slowed – India added only eighteen runs in the batting powerplay, which was taken shortly after the wickets. After careful batting by MS Dhoni (44*) and Suresh Raina (38), India brought itself back to a winning position, requiring 40 runs from the last five overs, with six wickets in hand. Eventually, India needed 13 runs from the final over, which Dhoni scored with two balls to spare.

5th match

Batting first, Sri Lanka lost Upul Tharanga (0) in the first over, and was in a vulnerable position at 3/79 in the 20th over. Dinesh Chandimal (81) and Mahela Jayawardene (43) added 94 runs for the fourth wicket to bring Sri Lanka to 3/173 in the 36th over, but both were dismissed shortly afterwards, which stifled the Sri Lankan innings. Only 58 more runs were added in the 12.3 overs after Chandimal's dismissal, to take Sri Lanka to a total of 9/236.

In its chase, Gautam Gambhir (91) scored his second consecutive score of in the nineties to anchor the innings, while nobody else in the top order was able to manage more than twenty runs. Gambhir was joined at the crease by MS Dhoni (58*) in the 28th over, and the pair added sixty runs before Gambhir was run out in the 41st over, with the score 5/178. Dhoni batted patiently with the lower order, and batted into a position where it needed 24 runs to win from the last two overs with three wickets in hand: Angelo Mathews conceded 15 runs from the 49th over, including a wide and a no ball, and Lasith Malinga conceded 8 runs from the last over, including three from the final ball, to tie the game.

There was mild controversy when it was later discovered that India's 30th over had been called off after only five deliveries.

6th match

After winning the toss and choosing to bat, Australia's top and middle orders were decimated by Sri Lanka's bowling. When rain interrupted play after 26 overs, Australia was struggling at 6/88. After the resumption, with the innings shortened to 41 overs, Australia managed to extend its score to 158, mostly through the batting of David Hussey (58), who was the only Australian batsman to pass a score of twenty runs, and his 49-run partnership with Mitchell Starc (17) for the ninth wicket. Thisara Perera (2/29 from 7 overs) and Farveez Maharoof (2/18 from 8 overs) finished with the best bowling figures for Sri Lanka. The target was adjusted down to 152 by the Duckworth-Lewis method.

Sri Lanka had no difficulty chasing down Australia's total, winning in the 25th over, at a run rate of 6.28, to claim the bonus point. Mahela Jayawardene (61*) top-scored in the run chase.

7th match

In a solid performance by the entire batting line-up, Australia reached 5/288 in its innings. Four of the top five batsmen – Matthew Wade (45), David Warner (43), Peter Forrest (52) and Michael Hussey (59) – passed forty runs to set a strong platform, and middle order batsmen Daniel Christian (30* from 18 balls) and David Hussey (26* from 20 balls) accelerated through the death overs. Irfan Pathan (3/61) was the best of the Indian bowlers.

In reply, India's top order fell cheaply, with Brett Lee and Ben Hilfenhaus each taking two wickets to reduce India to 4/36 in the 11th over. India never recovered from that start, and only MS Dhoni (56) could provide any significant resistance, as India was dismissed in the 44th over for 178, conceding a bonus point. Hilfenhaus finished with 5/33 to win Man of the Match, and Brett Lee also took one more wicket to finish 3/49.

Indian captain MS Dhoni was charged for India's slow over rate, which saw the Australian innings run half an hour longer than scheduled, and he was suspended for India's next ODI. It was Dhoni's second suspension for a slow over rate during the summer, after missing the fourth Test against Australia in January.Dhoni suspended due to slow over-rate

Australian Ricky Ponting was dropped after this match, after failing to reach double figures during the series.

8th match

As Australia had done in the seventh ODI, almost Sri Lanka's entire batting line-up played well in the first innings – Mahela Jayawardene (45), Tillekaratne Dilshan (51), Dinesh Chandimal (38) and Lahiru Thirimanne (62) set a strong platform, and Angelo Mathews (49* from 37 balls) and Thisara Perera (10 from 7 balls) accelerated at the death. Sri Lanka finished with 6/289.

Sri Lanka took three early wickets, including two to Nuwan Kulasekara, to reduce India to 3/54. Suresh Raina (32) and Virat Kohli (66) added 92 for the fourth wicket, to bring India to 3/146 in the 31st over, before Raina was dismissed. Sri Lanka regained its winning position when Kulasekara (3/40) dismissed Ravindra Jadeja (17), India's last recognised batsman, in the 38th over with the score 6/191. Irfan Pathan (47 from 34 balls) gave India some hope, but he quickly ran out of batting partners, and India was dismissed for 238 in the 46th over. Sri Lanka won by 51 runs, seven runs shy of the margin required to earn a bonus point.
