London, June 22 While Andy Murray is hoping to bring home the Wimbledon trophy, her mother has said that she won't be taking his granny along to watch him play because she's a jinx.

Murray's mum Judy thinks that Andy, 22, may lose his chances of winning if her mother, Shirley Erskine, 73, cheers from the sidelines.

This is because Murray lost the last three times his grandmother was watching him play.

The last occasion was when Judy took Shirley to see Andy play Juan Martin Del Potro at the Madrid masters in May.

"It was Andy's 22nd birthday and he was due to play Del Potro at 10pm," the Daily Express quoted Judy as saying.

"I made a booking and took granny with me. This was the third successive year I've taken my mum for Andy's birthday and he has lost each time," she said.

She added: "She is clearly a jinx and I'm not taking her again."

But Shirley is adamant to go there in person rather than watching at home in Scotland.

"I'm trying to convince the family I'm not a jinx because I want to be down there cheering Andy on. I fully intend to go to Wimbledon and if I could do anything to bring Andy good luck, I would," she declared. (ANI)
