A resurgent Bernard Tomic has set his sights on revenge in 2013 as he looks to bury a turbulent 12 months in the past.
Tomic, who came under fire following a season of poor form, allegations of tanking and altercations with police in 2012, continued his impressive start to the year with victory over fellow Australian Marinko Matosevic at the Apia International Sydney on Tuesday.
The 20-year-old is unbeaten in 2013, having also accounted for Novak Djokovic, Tommy Haas and Andreas Seppi at Hopman Cup in Perth, and feels he has a point to prove on home soil.
"Every player I play now I want to win and give myself the best opportunity and chance to win," Tomic said.
"Every match I go into now I believe I can win and I'm going to stay in there the whole match and fight for every point.
"Before I used to train a lot and get distracted and not play the right tennis.
"Now it's all about giving 100 percent on the court. Whether it's two, three hours or an hour on court, it's just focusing and doing the right things.
"That's why I think I've been playing good tennis the last few weeks."
Tomic said he had learned to stay focused and moved on from last year, when he was too easily sidetracked on and off the court.
"Once you learn how to keep it up, it will come naturally and you don't have to think about it," he added.
"The more I'm doing it now the less I'm thinking about it and I'm just doing it; whereas before last year it was very difficult to think about it."
Tomic will meet fifth seed Florian Mayer in the second round in Sydney in a bid to avenge his poor record against the German.
"I played Florian twice last year and got my ass kicked in both," he said.
"So it will be an interesting match. I'm looking forward to it and hopefully this time I can beat him."
