The golfing world remembers Tiger Woods at the 2008 U.S. Open, where he sank that pressure-packed putt on the 72nd hole to force a playoff.
We all remember Steve Stricker at last year's John Deere Classic, where he sank a 20-footer from the back of the green for the victory.
Of course, the golfing world has to remember Graeme McDowell at the 2010 Chevron World Challenge, where he made two clutch 20-footers to take down Tiger Woods.
None of those exciting moments would have happened without the putter, and those golfers who wield the flat stick the best.
Without further ado, let's take a look at some of the best clutch putters on the PGA Tour.
