A controversial call against Alicia Molik at the Australian Open yesterday has prompted renewed calls for more technology to help umpires and line judges.

The United States Tennis Association (USTA) said it was looking at using electronic aids at the US Open next September.

Television companies use computer-generated replays such as "Hawkeye" and "Auto-Ref" which might have helped Molik after an ace she served was wrongly called out depriving her of an 8-7 final-set lead over top seed Lindsay Davenport in their quarter-final.

The American then broke Molik and served out for victory. Molik said she would like to see technology used if it did not delay play.

"I think to a certain degree it may help," she said. "But on the flip side, it may hold up play. Tennis is a very flowing game, so I think to a certain extent it would disrupt players' routines and affect the timing of the way matches run."

Several players at Melbourne Park this year, including Serena Williams, have expressed their support for technology to be used, though Davenport said her mind was not made up.

"I've always been against electronic line calling," she said.

"It would be hard to do it for all the courts and I think it's fair that every player has the same circumstances."
