If they fall behind Australia in the first innings, the second innings will be very difficult for India. Because if Australia is 150 runs ahead of India at the end of the first innings then they will start with 151 runs in the second innings and if they can score 400 runs in the second innings then the target for India will be 550 runs which is very difficult to achieve against a team like Australia.
India all-out score of 296 runs in the first innings with a deficit of 173 runs does pose a significant trial ahead. But the positive aspect to focus on is Shardul Thakur's exception batting performance where he scored a well-deserved fifty 51 runs. Australia bowlers particularly Pat Cummins displayed their skill by taking three crucial wickets. Despite the uphill battle India resilience and determination can still lead to a competitive second innings and with the unpredictable nature of cricket i think anything is possible at The Oval.
