Melbourne  - Tomas Berdych has joined Roger Federer in slamming the Hawk-Eye electronic linecalling system after its failure struck him at a key moment in his losing fourth-round match to the Swiss star at the Australian Open.

It's no secret that traditionalist Federer has never been a fan of the system - and his poor record on challenges proves that point.

But the system really caught Berdych at a bad time when it failed to function on a challenge he made - likely because of a deep shadow over one side of the court in late afternoon.

Melbourne  - After a lifetime based in Australia,  may be planning a possible move to the US in hopes of extending his tennis career.

Hewitt, 27, wife Bec Cartwright and the couple's two children could be set for a shift of continent within months, according to Melbourne's Herald Sun - all part of a strategy to dispel any notion that the former number one might soon retire after his ranking dropped out of the Top 100.

Hewitt crashed out in the Australian Open first round.

Melbourne, Jan. 26 : Australian Open officials have said that they will prevent tennis player Jelena Dokic''s estranged father Damir from meeting his daughter should he attempt to gatecrash her Australian Open party.

The Sydney Morning Herald quoted tournament officials as saying on Monday that he is free to purchase tickets to Melbourne Park, but he would not be allowed to make contact with Australia''s comeback queen - unless given permission to do so by Dokic.

Melbourne, Jan. 26 : British tennis star Andy Murray's dream of lifting the Australian Open has ended. He lost to Spaniard Fernando Verdasco 2-6, 6-1, 1-6, 6-3, 6-4.

According to The Telegraph, Murray struggled throughout his match against Verdasco, making uncharacteristic errors from both flanks.

It was a fantastic result for Verdasco, the No14 seed from Spain, whose powerful forehand and dangerous serve held up under pressure. Verdasco will now face either James Blake or Jo-Wilfried Tsonga in the last eight.

Melbourne, Jan. 26 : Controversy surfaced at the Australian Open here on Sunday when tennis player Tomas Berdych questioned the accuracy of the Hawk-Eye electronic line-calling system at a vital stage of his quarter-final match against defending champion Roger Federer.

The system which simulates ball flight to determine close calls was unable to offer an opinion on a line call, leading to an angry Berdych questioning the chair umpire over the apparent failure of the system to show a simulation of a ball called out early in the fourth set, reports The Australian.

Melbourne, Jan. 25 : World No. 1 Jelena Jankovic was bundled out of the Australian Open on Sunday by Marion Bartoli of France.

Jankovic, a losing semi-finalist at Melbourne Park last year who is still chasing her first grand slam title, was beaten 6-1 6-4 in one hour and 22 minutes by the No. 16 seed in the fourth round.

Bartoli''s career highlight to date was reaching the final of Wimbledon in 2007, before eventually going down to Venus Williams.
