Scores:-

India’s Gautam Gambhir was unstoppable during his second successive Twenty20 half-century.
Though India lost the one-day series to Australia, India lived up to their world champions tag in the Twenty20, finishing with a thumping seven-wicket win in Mumbai.

Ricky Ponting's blazing 76 boosted Australian total but it was overshadowed by Gautam Gambhir's 63.Gambhir set the agenda in an emphatic manner, partnering Robin Uthappa and Yuvraj Singh in rollicking stands. Gambhir cut loose with a fearlessness that was missing in some of the 50-over games. The dance down the track was a regular feature but the chiselled square-cut was the sight of the evening.

Australia's bowlers had a tough time. Gambhir fell with 24 still needed, holing out to mid-on trying to end with a flourish.Robin Uthappa's 35, including six fours, went well with the fireworks illuminating the Mumbai skies. Virender Sehwag managed just 5 on his return but Yuvraj Singh swung India to the finish.

Ponting made good use of the advantage at the toss. Entering as early as the first over, after Adam Gilchrist slammed three consecutive fours before losing his middle stump to a incisive RP Singh.Ponting displayed controlled aggression. He threw his bat at anything wide of the stumps fortunate to see Mahendra Singh Dhoni unable to clasp onto a thick edge while lunging to the right and brought out the imperious pull when anything was short.

Harbhajan was India's most economical bowler, conceding just 17 in his four overs, and Kartik proved an able ally. RP Singh, largely erratic, should have ended with another wicket, with umpire Amish Saheba failing to detect an edge off Brad Haddin in the last over, but it did not make a difference in the final analysis. This was a Twenty20 and India showed their championship class.
