American club professional Chip Sullivan is having to cope with all sorts of emotions after making the halfway cut in his second USPGA Championship.

The 39-year-old's sister Kerry is suffering from what doctors have diagnosed as a fatal liver disease, while his wife Kari is expecting their third child.

"I have obviously got bigger things on my mind than golf, and I am hoping I can make it through the weekend," he said.

His sister was given six months to live and has already exceeded that.
