Golfing great Seve Ballesteros made his first public appearance on Sunday since undergoing four separate surgeries to remove a cancerous brain tumor. Ballesteros, a five-time major winner, was on hand for a Spanish league match at Racing Santander's El Sardinero stadium, where he received a standing ovation from the fans. Dressed in jeans and a dark blazer, Ballesteros, who lives close by, waved to fans and smiled. The 52-year-old underwent four operations to destroy a malignant brain tumor between Oct. 5 and late December, when he was finally released from Madrid's La Paz hospital. He is currently undergoing his fourth round of chemotherapy.
