"That's a life of a fast bowler. Sometimes it (injuries) just happens. Fast bowling is not a natural thing. Ishant has struggled with a few injuries. But when he is injury free he is a freak of a bowler. He can do some amazing things with a cricket ball. He is tall, he has got good pace, he hits the deck, he has got a slightly different action so he brings the ball in with his wrist. He has all things that can add up to be a very good fast bowler," Steyn said.
