Gorzny, who made his US Open debut, once had 5% chance of survival

American tennis player Sebastian Gorzny, who made his US Open debut on Monday, once had a 5% chance of survival. When Gorzny was 15, he suffered a seizure and was placed in an induced coma for four days. "The doctors aren't...sure what it was...but they're guessing a mosquito bite that led to some type of brain infection," the 22-year-old said.
