LONDON - Four-time Wimbledon champion Serena Williams has used her high-profile position to join the chorus supporting electronic line calling in soccer.

After repeated debacles and uncounted goals at the World Cup, tennis players are starting to realise how well the Hawk-eye system works to eliminate uncertainly in their sport.

Williams, who professes to be a football fan during the World Cup period, has now made her plea as calls are growing for an electronic judge on goal lines.

"I just think it's unfair that you can make a goal, like USA did twice, and England did, and it cannot be a goal. I just think that's outrageous," she said.

"I think they should," she said of a possible opening to the once unheard-of possibility by Fifa. "It's just so frustrating, especially when you're rooting for a team." - Sapa-DPA
