Australia won the toss for the third time in the series, but have chosen to bat first on this occasion. Perhaps, because the surface at Pallekele could be better for the spinners in the second innings. Or, maybe because they want to challenge themselves in a different direction. They had won both the T20Is in Colombo chasing.
