Brian Davis has warned that somebody could miss out on Open glory at Sandwich on Sunday because of a mobile phone.

Davis' third-round charge on Saturday was halted when he was disturbed on the 16th green and three-putted.

"It could cost somebody the Open," said the 28-year-old Londoner after two bogeys in his last three holes left him with "only" a 68 and five-over total.

"Imagine it happening on the 17th tomorrow. I should have backed off my putt (a four-footer). It was a bit of lack of experience and I regret it now - you'd think I would have learnt after eight years on tour.

"All we heard all day were messages going off. At the US Open last month we heard nothing."

In Chicago the United States Golf Association placed a ban on mobile phones and Davis said he would like to see the Royal and Ancient Club go the same for the Open.

"It's annoying and I'm sure it would not kill people to be without their phones for a while."

Davis was watched by wife Julie and her father, former England goalkeeper Ray Clemence.

"He seems to bring him good luck, but he's got a charity golf day with the Variety Club tomorrow, so I don't know whether he can make it," said Julie, who is still undergoing tests after collapsing last month.

"It's been a bit of a nightmare and I have to have somebody with me at all times in case I black out again. This is the first time I've been to a tournament since May and with Brian doing so well I've really enjoyed it."

Davis hoped he had not caused her any anxiety as he battled to make the halfway cut, finally surviving thanks to a 12-foot closing putt.

Resuming on eight over he went to the turn in 32 and the next five holes comprised birdie-bogey-birdie-bogey-birdie as he threatened to get back in contention.

Then came the two late bogeys, though, and the task tomorrow is now about trying to climb into the top 15 to guarantee a place in next year's event at Royal Troon.
