Piyush Chawla and Harbhajan Singh spun India to a thumping 38-run win over Australia in their first warm-up game of the Cricket World Cup in Bangalore on Sunday. Chawla and Harbhajan exploited the conditions to perfection and troubled all the Australian batsmen on a turning track at Chinnaswamy Stadium to earn a morale boosting victory for India.Earlier, Indian batsmen failed to live up to expectations as they were bowled out for 214 in 44.3 overs after electing to bat. Chasing a modest 215 for a win, Australia were cruising at one stage on 118 for two before Chawla and Harbhajan cast a web around Ricky Ponting's men to bowl them out for 176 in 37.5 overs.India play their second warm-up game against New Zealand in Chennai on Wednesday.
