Two of the favourites for the 2014 World T20 in Bangladesh got off to losing starts on Sunday in Mirpur, as Australia and West Indies fell to Pakistan and India, respectively.
Pakistan's bowlers managed to restrict Australia well, and despite a 33-ball 74 from Glenn Maxwell, they fell 16 runs short of the 191 target.
And an impressive display from Pakistan with bat and ball may have Australia legend Shane Warne rethinking his predictions for the tournament:
Meanwhile, the West Indies were tied up by some excellent bowling and could only post a score of 129 which was chased down easily by India who won by seven wickets.
Read on for a look at the updated Super 10s standings and analysis of the top run scorers.
Super 10 Group Tables
Umar Akmal produced the highest score of the tournament so far with an innings of 94 off 54 balls, as Pakistan picked up their first win of the tournament after an opening loss to India.
Umar's innings included nine fours and four sixes and set Pakistan up to post an impressive 191-5 from their 20 overs which they managed to defend despite a mighty effort from Australia.
It was the best knock of my career simply because we were under tremendous stress having lost our first match.
The management backed me to go out and express myself with the bat and I played my natural game.
And teammate Shahid Afridi congratulated him on his innings after Pakistan's win:
He now has 127 runs for the tournament which puts him at the top of the table for runs scored in the Super 10 stage, per ESPN Cricinfo.
An astonishing innings from Maxwell looked to have set Australia on the road to an easy victory against Pakistan.
But some excellent bowling tied his teammates in knots, with Aaron Finch the only other Australian to reach double figures.
His 74 is the second-highest score of the tournament so far, and his 18-ball half century is the fourth -fastest in T20 internationals, per ESPN Cricinfo.
The breakdown below shows how each Pakistan bowler fared against Maxwell's hitting:
Australia are still very much in with a chance of qualifying from Group 2 to the knockout stages, especially if Maxwell's form stays at this level.
But he will need help from people other than just Finch, who scored 65, if they want to overcome the likes of India.
Virat Kohli scored 54 as India cruised to victory against the West Indies, and he now sits second in the Super 10 top-scorer list with 90 from the first two innings, per ESPN Cricinfo.
Setting a target of only 130 for victory, there was no need for India to score at an electric rate.
However, Kohli kept the scoreboard ticking over, his runs coming off 41 balls and including five fours and one maximum.
He and Rohit Sharma, who scored 61 not out, put on 106 runs for the second wicket and effectively guided India to the win.
Despite winning with only two balls remaining, India were never uncomfortable, and they look like a force to be reckoned with at this early stage.
