Pace spearhead Ishant (2-68) picked the all-important wickets of Lahiru Thirimanne (62) and Dinesh Chandimal (11) to help India gain a sizeable 87-run first-innings lead after packing Sri Lanka for 306.
The visitors then ended Day 3 on 70 for one, to gain an overall lead of 157. Gavaskar was all praise for the bowling show led by Amit Mishra (4-43).
"I think they are in a very good position. It would have been better if they would have taken 30-40 runs more lead. But by losing just one wicket by the end of the day, they have given themselves the option to go hell bent for leather tomorrow.

Critics maybe gunning for Ajiinkya Rahane's failure to perform at the No.3 position but Gavaskar backed the talented youngster to come good very soon.
"I just think that a batsman who is comfortable at No.5 and then coming in at No.3 is a bit difficult. But having seen Ajinkya Rahane making adjustments to his cricket all around the world, he will succeed giving a long time and will make a success of the No.3 spot. Technically and temparamentally he is very good," the legendary opener said.
The cricketer-turned-commentator also urged the pundits to stop analysing Virat Kohli's leadership skills so early in his career.
"Why do we we make so much of Virat's captaincy? Look he is into his fourth or fifth Test. He is going to make some mistakes, it's part of the game. He is learning and look at the way his batting has improved by leaps and bounds because he is such a committed cricketer. Give him a little more time," he said.
