Greg Norman stays focused after split with Chris Evert

Greg Norman vows the break-up of his marriage to Chris Evert will not be a distraction to his international team as they prepare to face the United States at golf's Presidents Cup in San Francisco this week.

The Australian appeared at the captain's news conference at Harding Park Golf Course just days after it was revealed his 15month marriage to the former tennis star was over.

"I'm not going to talk about my personal life right now," said Norman, whose right arm was in a sling after shoulder surgery.

"The situation now is we are here for the Presidents Cup and it's all about that event. My guys are in a great state of mind and we haven't even talked about my marriage. We talked about my shoulder - it's pretty hard to ignore that."
