Hewitt, Tomic put Australia up 2-0 in Davis Cup tie against Poland Australia are on the brink of re-joining the World Group for the first time since 2007 after going two rubbers up against Poland in their David Cup playoff. Lleyton Hewitt celebrates his victory in the first match of the Davis Cup tie against Poland at the Torwar Hall in Warsaw. LLEYTON Hewitt and Bernard Tomic put Australia on the brink of a long-awaited return to the Davis Cup World Group with clinical straight-set wins on day one of their playoff in Poland. Ageless warrior Hewitt carried on from his stellar run at the US Open with a 6-1 6-3 6-2 demolition of Lukasz Kubot, Poland's No.1 in the tie after the injury withdrawal of star Jerzy Janowicz. Neither player dropped serve in a dream start for Pat Rafter's squad. Australia can seal a return to the competition's top tier for the first time since 2007 if the unbeaten duo of Hewitt and Chris Guccione win Saturday's doubles. Feeling like he'd lost none of the form from his run to the last 16 at Flushing Meadows, Hewitt was off to a flyer against 70th-ranked Kubot. Kubot tried to rally but 58th-ranked Hewitt's clean striking and smart tactics on serve never allowed him into the match as the 32-year-old wrapped up victory inside two hours. Tomic was made to work harder for victory against 113th-ranked Przysiezny, called in to replace Wimbledon semi-finalist Janowicz. But the world No.51 served beautifully - hitting 86 per cent of first serves in the opening set - and showed coolness under pressure in the big moments. "It's probably the best I've served this year," said Tomic, who has endured a tumultuous year including the recent conviction of his father and coach John for assault. I'm very happy LLeyton won and that gave me a lot of motivation. It's huge for us to be 2-0 up. It's been a long few years trying to get that shot. I think we've managed to be at 1-1 on the second day of those ties and now we're up 2-0 and it's very important.  The 20-year-old is building an impressive Davis Cup record with 11 wins in 13 singles rubbers. Hewitt and Guccione face Marcin Matkowski and Mariusz Fyrstenberg tonight (10pm AEST).
