Ishant Sharma, who took a five-for at home after a gap of 12 years, attributed the variety he has added to his arsenal for the swing in fortunes.“I was looking for variety for quite some time. For instance, I was usually bowling outswingers to the left-handers. But I worked on a delivery that comes straight after pitching while appearing to move away. I think it is quite effective as I got three wickets with the delivery today [Friday],” said Ishant.
