This is the kind of mess that makes you so uncomfortable you almost can't watch it all. But of course, you do watch it all. Three times. Three times he missed this seemingly unmissable putt. Maybe we shouldn't count the last miss because it was likely the result of equal parts anger and shame, but still, four-putting from that close is something remarkable.
Shane Bacon, over at CBS's Eye On Golf has even more context for Schwartzel's disastrous Sunday.
The former Masters champion had three double-bogeys over his last five holes, and four double-bogeys on his day as he posted an 8-over 79 and dropped him 40 spots at the Deutsche Bank Championship.
That is a raw way to end your weekend.
