AUGUSTA, Ga. — As Tiger Woods was making his stirring late charge up a bunched Masters leaderboard Friday, he was chasing a formidable cast of rivals that included six major golf championship winners.
Any one of them could have tripped up Woods’s run at the lead as the tournament reached its halfway point.
Instead, for one alarming moment, it appeared that a stumbling security official at Augusta National Golf Club might derail Woods’s most memorable Masters surge in years.
After Woods hit a shot out of the trees left of the 14th hole, a sprinting uniformed guard, who was trying to control the crowd just behind Woods, slipped on wet grass and slammed into Woods’s right ankle.
