Australian’s have always been suspicious of Sri Lankan pitches. There was the 2011 Galle pitch which the ICC rated as Poor. And many of the Australian batsmen who played in Pallekele in 2016 said they saw what appeared to be demons residing under the grass.
Of course, the Sri Lankan’s have always been accommodating to these worries ever since the Ceylonese National Team prepared a pitch two yards short when the Australians played them in 1948.
Hey, it can happen to anyone.
