Ashwin may well have got a touch, but non-striker Finch had his bat grounded well behind the line, so the partnership continues.

Thanks, James. The platform Australia are building here is looking a lot more solid than the aforementioned viewing platform suspended above the SCG - you wouldn't get me up in that one... Ashwin to continue after four wicketless overs, Smith pushes one straight back into the stumps at the bowler's end and the umpire wants to see if Ashwin got a hand onto it...

Steve Smith is ready to kick this innings into overdrive now. He gets deep in his crease, picks the length early from Jadeja, and slaps a perfectly serviceable delivery for a big six to cow corner. Australia are in charge at the mid-innings point, which is my cue to hand you over to Mark Mitchener.

"MS Dhoni's got to do something here and create an opportunity. He can't just let this game drift away - it's all too easy for Australia at the moment as they're picking up singles, and the odd long-hop is being taken for three or four. If these two are still batting at the 35th over, India could be chasing 320, 340 or 350."

Ada: At this rate those people in the high seating might get scared if Maxwell comes in with five overs remaining. Helmets on.

prayags: Just came into office... boss has taken the day off... lol.

Steve Smith is looking so assured out there now, picking up three with a cover drive against the spin of Ashwin. This is only the second 100 partnership against India in the tournament - MS Dhoni's side desperately need a wicket here.

"There have now been 15 century partnerships for the second wicket in this World Cup. This is easily the most for any wicket. The next most is 10 for the fifth wicket."

"I like the way the Indians now cause a little bit of a stir when they're fielding. I thought umpire Kumar Dharmasena got involved too quickly the other day between Wahab Riaz and Shane Watson."

That was always an optimistic review, and it shows just worried India are by this burgeoning partnership. Finch takes it past the 100 mark with a single into the leg side.

"He's a long way down, but the technology doesn't worry about it. The Indians in the crowd like this - but it's umpire's call on impact. A fractional call, but the umpire gives that benefit of the doubt to the batsman. Well done the umpire, though there's a minor altercation between Smith and Rohit Sharma."

You can understand India going for a review - they need a moment in this match. But the replay shows that Finch got himself outside the line of the stumps as he went to sweep, and India have lost their one and only review.

"It looked very full, which is always dangerous for a sweep, Jadeja's trying to convince his captain and they've gone for a review. But an umpire's call will go with the batsman."

Aaron Finch has struggled against spin so far, but he eventually shows signs of adjusting to the lack of pace, waiting on a short ball from Ashwin and cutting hard past point for four. Finch isn't at the top of his form - with his strike rate hovering at just over 60 - but for now, he can afford to hang in there and punish the bad ball with Smith in such fluent touch at the other end.

"Our old friend the viewing platform, which first appeared in last year's Ashes, is back in operation today. It's so high above the corner of the Bradman Stand and scoreboard that you can't see it from our position in the media centre. Are the people in there actually having fun? It can't be good to have to be strapped in to your seat so you don't fall to a grisly death?"

Jadeja keeps up the good work with another parsimonious over, yielding just two singles. India's spinners are dragging their side back in to the match.

Scorecard

Shirish: Run rate nearly six. Nothing in the pitch for bowlers. India must bowl well the remaining overs!

Zubair Ahmed: I drove to office in record time this morning. No traffic. It seems India's glued to TV at home watching cricket semi-final.

Steve Smith clearly expects this trial by spin to continue - he's dispensed with his helmet and gone for the canary-yellow cap. Examples of the best and worst of Indian fielding as slack chasing by Mohit allows Finch to pick up three behind square, before a good stop at point by Rohit saves four.

"Steve Smith is the second Australian to reach 50 in four consecutive World Cup innings after David Boon (1987-1992)."
