"I don't think so (lost pace). I haven't measured my speed, but I am not bowling slow," he told PTI ahead of his side, Jharkhand's maiden Ranji Trophy clash against holders Mumbai commencing tomorrow at the Wankhede Stadium here.
"I have been bowling well. I train really hard. That is one thing I learnt from (Australia pace guru) Dennis Lillee, that as long you are a fast bowler, you have to train really hard. Since 15, I have been at the (MRF) pace foundation (in Chennai). I do train very hard and try to bowl as quick as possible," he insisted.
He has played for Jharkhand in three matches this season and picked up 11 wickets.
The 24-year-old said he wasn't planning to undergo the surgery but had no choice.
"I was not supposed to undergo a back surgery in the beginning. But later on I didn't have an option, so there wasn't much thinking about it. I had to get a surgery done towards the end. It is good that it has worked for me."
"It is difficult. Once you get there you should always retain your place is what I feel. Especially when you are not in the team because of an injury...It is disappointing. Injury is something you don't have control over, so I don't give it much thought. I trust myself a lot and back myself a lot to make a comeback."
Aaron had to miss the tour of Australia in December 2011 due to stress reaction in the back.
