Defending champion Lleyton Hewitt bounced back from a set behind to win a thrilling quarterfinal against Slava Dosedel at the Australian Men's Hardcourt Championship in Adelaide yesterday.

Dosedel, who earlier in the day ousted top seed Patrick Rafter 7-5 6-4, tired as Hewitt reeled off the last six games to defeat the Czech 4-6 6-4 6-2.

The 17-year-old from the host city now plays Jason Stoltenberg in an all-Australian semi-final today. Fourth seed Stoltenberg breezed past Zimbabwe's Byron Black 6-3 6-2 in their last-eight clash.

Meanwhile, Scott Draper moved into the semi-finals with a 6-7 (7/9) 6-4 7-6 (7/5) victory over fellow Australian Michael Tebbutt, who double-faulted on match point in the final tie-break.

Draper will now meet second seed Thomas Enqvist after the Swede disposed of Slovakian Dominik Hrbaty 6-2 6-4.
