Lleyton Hewitt has revealed he is helping Bernard Tomic after the wayward prodigy was dumped from Australia’s Davis Cup team. Hewitt claims Tomic has the potential to cement a top-10 ranking despite the 20-year-old’s surprise Davis Cup axing last week. Disappointed with Tomic’s attitude, Davis Cup captain Pat Rafter dumped him for the February tie against Chinese Taipei in Taiwan. Hewitt said he agreed with Rafter’s decision, believing Tomic needs to learn the hard way. He then revealed he has become part of the troubled star’s support network.
