Visakhapatnam, Oct. 12 -- Such is the excitement for the World Cup's first sold out fixture between India and Australia that locals at the Rushikonda beach are discussing the logistics for match day. "Australia, danger team", chimed a vendor at the beach, which was met with a nod by an impressed spectator, who expects to be in the 26,000-capacity stadium on Sunday. Australia, the seven-time winners, are unbeaten in the tournament. India have a lopsided record against them in ODIs. Although closely contested, they also lost the three-match series 2-1 in the lead-up to the World Cup. What was expected to be India's most challenging phase in the tournament began in grim fashion here. They were expected to be challenged by SENA (South Africa, England, New Zealand, Australia) countries and a spirited South Africa handed them a three-wicket defeat and reality check on Thursday. India are under pressure to bounce back as they face their most formidable opponents. However, India have a few things going for them. Australia are usually seen as unbeatable, and India's three wins in the tournament history can help battle those nerves. The sensational 171* by Harmanpreet Kaur to knock them out in the 2017 semi-final is still fresh in memory. India also know the pitch conditions well. "The camps here really helped because we got familiar with the ground conditions, dimensions, how fast the ball travels, which helped our fielding. Understanding how the pitch behaves after the first innings has also been useful," said Sneh Rana. But top-order batting has been the cause of India's woes thus far. A trend in this World Cup has seen left-arm orthodox spinners being highly effective, almost game-shaping. They have taken 40 wickets in 25 innings at an average of 19.02 and economy of 4 until Friday's game. Their success suggests control and penetration in the middle overs, which is where both India and Australia rely heavily on spin. Although India historically rely more on off-spin of Deepti Sharma and Sneh Rana, India will be tempted to use N Sree Charani strategically against Australia's middle-order right-handers. They may even bring in the experienced Radha Yadav, also a left-arm spinner. Radha was doing the drills one day before the match eve, as were Renuka Thakur, Smriti Mandhana, Harmanpreet Kaur, Arundhati Reddy and Amanjot Kaur. India opted to bat against U-19 Andhra net bowlers, facing a combination of one left arm spinner, one leg spinner, besides right-arm spinners. On match eve, Uma Chhetry, Jemimah Rodrigues and Pratika Rawal turned up for optional practice with all opting to target range-hitting against slow left-armers. India have been prioritising batting depth so far and instead compromising on a sixth bowling option. Against Australia, however, that strategy could shift. So far, India have been taking their dots too literally. They have a dot-ball problem and it's been a predictable pattern so far - especially in the middle overs. They got away against Sri Lanka (dot 43%) and Pakistan (56%) but against stronger oppositions, it came back to bite, as they found out against South Africa (58%). Over the three matches, the percentage has become progressively higher. Of all the teams, Australia are least likely to be generous about it. "It seems to be throughout the middle overs that some sides have been managing to squeeze oppositions, but you can get off to a good start during the powerplay and set a platform. There's a fine balance in that regard, but I think both of us at the top are quite aggressive so we're not exactly going to curb that at any point," said Australia captain Alyssa Healy....
