Harrison says he could surprise Djokovic
Novak Djokovic was well aware of up and coming American Ryan Harrison, even stating that he knew how to beat the 20-year-old, but his second round Australian Open opponent is sure he may be able to give the world No 1 a surprise on Wednesday.
Two-time defending champion Djokovic will meet Harrison, for the third time in their careers, on Rod Laver Arena, and said after his first round victory over Paul-Henri Mathieu that he felt he knew the American's game and how to beat him.
Harrison, however, underwent intensive training, physical conditioning and scientific physiological testing during the off-season in order to help take his game to the next level.
He was told to lose weight in order to ensure he was more effective right to the end of long matches and how to manage his nutrition better and his first round win over Santiago Giraldo had given him confidence to press on against the Serb, he said.
"It's an opportunity. I have confidence in myself after all the work I have done during the off season," Harrison told reporters ahead of the Djokovic clash.
"I feel different this year, mentally and physically I have put myself into a position where I feel that I'm going to go forward.
"I know that I've got myself into a better condition where I will be stronger and faster than the last time we played (in the second round at Wimbledon last year).
"On top of that I'm going to try and play my game... try to control my side of the net... and not get caught up in the hype of the situation and how good he is."
