Novak Djokovic found himself mired in the muddy waters of tennis politics a day before the start of the Australian Open this morning.

Number three seed Andy Roddick beat fellow American Justin Gimelstob 6-1 7-5 7-6 (7-3) in their rain-delayed first-round clash on Court One at Wimbledon.

Former champion Lleyton Hewitt was made to work unexpectedly hard by unseeded American Justin Gimelstob before reaching the fourth round for the fourth time in six years.

Tim Henman today received plenty of support, some from highly unlikely sources, ahead of his second-round match at Wimbledon.

Top seed Lleyton Hewitt and sixth seed Andre Agassi both moved comfortably into the third round of the US Open with straight sets wins.
