WELLINGTON (AP) New Zealander Steve Williams doesn't believe his job as Tiger Woods' caddie is under any threat, despite media speculation about their 11-year association and concern over the champion golfer's form.

Williams told New Zealand radio Wednesday that he and Woods remain close friends and there is no possibility their working relationship is about to end.

"I'm sure if there was going to be some sort of parting of the ways, I'd be the first to know," he said. "From my point of view, I don't see any chance of that happening."

Williams said Woods had no plans to change his key personnel, though he has struggled to regain form after taking a break from the PGA Tour amid revelations of marital infidelities.

"People speculate. He's not playing well and his results aren't what we're used to," Williams said in the radio interview. "Tiger and I are very good friends and we've been through a tough time, there's no question about that."
