La Paz hospital said in a statement that the 51-year-old Spaniards condition was evolving favorably, and marked no change from the last update that was released Wednesday.
Ballesteros, a five-time major winner, remained in intensive care one week after a 6 1/2-hour operation to remove the brain tumor and reduce swelling around the brain. It was his third operation since being admitted on Oct. 6 after fainting at Madrids international airport.
Ballesteros was admitted to the hospital Oct. 6 after briefly losing consciousness at Madrids international airport. Eight days later, a sizable part of the tumor was taken out.
Ballesteros tumor is an oligoastrocytoma, which affects cells that cover and protect the nerve cells in the brain and spinal cord. In an earlier operation, part of his skull was removed to allow room for the swelling brain to expand.
Ballesteros won the British Open three times and the Masters twice. He captured a record 50 tournaments on the European Tour before retiring last year because of a long history of back pain. He has since concentrated on golf course design.
Ballesteros revolutionized European golf. After the Ryder Cup was expanded to include continental Europe in 1979, he helped beat the United States in 1985 to begin two decades of dominance. He also captained Europe to victory in 1997 and teamed with Jose Maria Olazabal in one of the most formidable partnerships in Ryder Cup history.
