Tomic aims to sharpen mental game

Teenager Bernard Tomic, who won both his matches for Australia in a Davis Cup zonal tie against South Korea, said he will work on improving his mental game in the coming months.  "Every great sportsman whether it is Federer or Nadal, they have areas where they can improve and I need to improve to become stronger mentally on the court," Tomic told reporters. "The biggest problem with me is, now that I am coming up I have to play a lot of lower-ranked players (I'm expected to beat). Look at Federer and Nadal, it would be very difficult for them always playing guys that are in the top 100…I can play on clay if I am in the right mindset. I don't move as good as the other players, so when I am down a set and a break it is tough for me to come back. I have to work on developing my game in the next few weeks against these players ... (if I want) to get to the semis in the French."
