Golf fans worried when Sam Snead, 85, was stricken with what appeared to be a stroke last week. During his annual five-hour drive to the Masters, Snead had gotten dizzy. "I'd eaten a bad piece of chicken, and I upchucked a bit," he said, forthright as ever. Less than 48 hours later, after a round of tests at Augusta's University Hospital, he moseyed past the clubhouse at Augusta National and hit his ceremonial tee shot on schedule. "Dad's tough," said Jack Snead, his son and caddie. "As a kid, he had his tonsils taken out in a dentist's chair." Jack recalled how his father, who bogeyed the 18th hole of a playoff to lose the 1947 U.S. Open, "would lay abed thinking about that." He said Sam enjoys tutoring "younger guys like Chi-Chi and Tom Kite" but would give his right arm to coach John Daly: "He'd caddie for that guy if he could. He says, 'If I told John Daly what club to hit every shot, and what kind of shot, he'd win every time.' "
