Finch still looks a little scratchy and Umesh Yadav induces a few oohs and aahs with an outswinging yorker that just defeats the opener's groping outside edge. A very good over for India, just one off it.

Aaron Finch has been looking - without much success - to smash it around early on, but will the loss of his opening partner force him back into his shell a bit? The Victorian has found runs elusive in this tournament since his century against England in Australia's opening match.

He finds the rope for the first time with an uncharacteristically effortless shot, easing Shami down the ground with the full face of the bat.

Pete Naylor: How come Shami couldn't hit these kind of lengths in the Pataudi Trophy last year? He seems more interested now it's an ODI...

Steve Smith is the new man - he has been in imperious form this Australian summer and his team need him to steady this innings early on here. He provides compelling evidence of his superb touch with a peachy cover drive for four.

"Very, very good from Yadav, Dhoni and India. At the start of the over, Dhoni put his arm around the bowler, who had been hit for six from the last ball of his previous set. Square leg dropped back to the boundary, leaving the gap where Warner was trying to work the ball. The roar when the catch was taken was enormous, proof of who the crowd is backing."

"You get an impression of how many Indian fans there are here after that! Warner looked in great nick, unlike Finch, and I wonder whether with long leg up, he was trying to turn it fine for four - but got a leading edge and it ballooned oh-so-gently to mid-off. Early drama and terrific excitement, the SCG feels like the Wankhede Stadium at the momenet."

The dangerman is back in the sheds, and India have an early breakthrough! Finch seemed to be the man under pressure early doors, but it's David Warner who perishes - he tries to work the ball to leg but the ball balloons off a leading edge and plops into the hands of a gleeful Virat Kohli at cover.

After Shami starts with a wide, Finch is hit in front, big appeal for leg before, looks close... but India opt against a review - a wise choice as the ball-tracker suggests it would have sailed just over the stumps.

But the right-hander doesn't look in the best of nick, playing and missing before opting for the safety-first option and shouldering arms to the last ball. A wide and six dots mean it's a better over for India. (And would have been a maiden prior to about 1984 when wides and no-balls were charged against the bowler for the first time).

"That was economy from Warner - it only cleared the rope by about 18 inches. It wasn't high enough - only about belly-button high. At the moment, you want to bowl to Finch, not Warner."

"If you're going to bowl short to Warner, you want to have a bit of Wahab Riaz's pace about it. That won't trouble him."

Umesh Yadav opens up from the other end. Warner hits the first convincing shot of the day, punching a slightly overpitched delivery back down the ground for four. The outfield looks pretty brisk. Warner can be such a dangerous batsman if you don't get him early on, and he looks to be into his stride quickly here, rocking back on to the back foot and pulling Yadav into the stands at midwicket for the first six of the match.

"It feels like being at Mohali in 2011, when India beat Pakistan in the semi-final, again! World Cup semis and national anthems being played... These are moments you live for. Electrifying."

"Not much swing but a few nerves, a few plays and misses. Yadav will be quicker, but I don't think short balls will disturb Warner and Finch."

Mohammed Shami's first ball draws a nervous prod from Aaron Finch and a huge roar from the massed Indian fans as it nestles in MS Dhoni's gloves. This does not feel like an away match for India. And then Shami gets one to hoop and strike Finch on the pads - big appeal, but it was definitely sliding down leg.

That brings David Warner on strike, and Shami strikes a psychological blow first up, inducing a big swing and miss from the feisty opener. Warner then collects the first runs off the bat with a single into the covers.

David Warner and Aaron Finch are padded up and ready to go. Mohammed Shami has the new nut in his hand. The SCG crackles with anticipation. We're all set.

"It's brilliant theatre; the music, the flags, the applause. As India waited at the top of the pavilion steps to emerge for the anthems, hundreds of cameras were pointed at MS Dhoni's men. I'm not sure I've ever seen so many people with their backs turned to the field."

"When you play Australia you've got to come out of the traps sharply, so Yadav, Shami and Mohit Sharma have to hit their lengths. The three Indian seamers have been one of the factors to make the difference in this tournament."

A rousing rendition of Advance Australia Fair completes the anthems. Few signs of nerves from either side. India huddle up, it's time to get down to business...

Rajendra Prasad: Have a feeling that Warner gets out in the first over.

Kishin Mahtani: Clash of the brats as both play against the spirit of the game. Gentleman's game so please both sides remember kids watching.
