Pat Rafter in tennis comeback playing doubles with Lleyton Hewitt Pat Rafter hopes they don't drug test for chocolate these days, because then he might be in trouble. He believes he will be the worst player to participate in this year's Australian Open, he's not sure he'll be able to return anyone's serve and half hopes he won't have to. But for now, Rafter is Lleyton Hewitt's 41-year-old partner in the men's doubles - 11 years after he retired from the singles tour and nine years since he managed his last doubles match. The idea was put to him by Hewitt, who wanted to play more than just singles at the Open. But his priority is the singles and should he win his first-round match against Andreas Seppi and decide he needs some rest before his second match, Rafter's comeback may be over before it begins. Pat Rafter with Rafael Nadal. My mates are sending me texts saying, 'can you please work on your returns?' I'll definitely be the worst player in the competition out there, but I'll have fun," said Rafter, whose return would have been more complicated had he not been out of the game for so long. The two-time US Open champion is not on the retired players' list introduced a few years ago, meaning he did not have to wait three months to rejoin the tour under anti-doping rules. He and Hewitt were given a wildcard by Open organisers, and are drawn to play American Eric Butorac and South African Raven Klaasen in the first round. Nothing is happening just yet, to be honest. We're in the draw, but it will all depend on how he goes. It's really important for him to play great singles. That's what it's all about," Rafter said. He still likes playing competitive matches. If he gets through the first singles, feels comfortable, is feeling he might want to play, it's whatever Lleyton wants. Either way, neither Rafter nor Hewitt expects his comeback to last until the end of the month, when Australia will play its first Davis Cup world group match in seven years against France. Rafter plans to be sitting by the court as captain by then, stepping on it only to help players warm up. The hardest part about being around 40 is keeping your body in shape. It's tough, I must admit. You don't look after yourself like you did. You're not in the locker room all the time. It's just a bit of fun. Doubles; half a court. Hewitt won't be too demanding a partner. "I hope I don't have to carry him too much," said the 32-year-old, who will play world No.25 Seppi on Tuesday. No, it's good for both of us. In the meantime, as Davis Cup captain, Rafter is looking forward to seeing whether Bernard Tomic can concentrate for every single minute against Rafael Nadal, what teenagers Nick Kyrgios, Thanasi Kokkinakis and Jordan Thompson make of their Open experience, and how long Hewitt can last. He loves it. He loves the occasion. He loves being out here, he loves playing. It's impressive," he said. For us in Davis Cup, we're so lucky to have him. He shows in leading the way for these young kids. They get to see the way he behaves and takes it all on. His professionalism, there's no one else out there like him.
