With his victory at the Players Championship, world No. 1 Tiger Woods notched his 78th PGA Tour victory at the age of 37, moving him closer to career-victory leader Sam Snead's 82 wins. Snead, for his part, racked up his wins over a 30-year career. Tiger's reached his mark in just 18 years.
Mind-boggling? Not when compared with the achievements on this list.
For all of the staggering achievements of his amateur and professional careers—from his three U.S. Junior Amateurs through his 14th major—there are a few that stand above the rest as truly mind-blowing.
