Ballesteros's health problems began last October
Golf legend Seve Ballesteros says he is "recovered 90%" and is hitting golf balls again after undergoing extensive treatment for a brain tumour.
The 52-year-old five-time major winner has had four operations and recently made his first public appearance since the start of his treatment.
"Now I am perfect, I can do any kind of sport, running, swimming, rowing and I am also hitting golf shots," he said.
"The fact that I was a sportsman and used to competing and fighting helped."
Ballesteros admitted he had "suffered like a dog" during his illness and will need to undergo a fifth round of chemotherapy, but his condition is improving.
"The results of my last tests at La Paz Hospital in Madrid showed I was on the right path," he said.
"I will go on working to get better each day."
