MADRID (AP) Seve Ballesteros was in stable condition Wednesday after the 51-year-old golf great had surgery on a brain tumor a day earlier.

La Paz Hospital said there were no complications from the surgery. Spanish state news agency Efe reported the operation lasted 12 hours.

The hospital said a sizable part of the Spaniard's tumor was removed. It was not immediately known if it was malignant and it would be several days before the results were announced.
