Louis grew up in South Africa and turned professional in 2002. He competed on various mini tours for a couple of years before earning his card to the European Tour in 2004.
Oosthuizen won the big one in 2010, when he snagged the Open Championship at St. Andrews. He lost two other majors in playoffs: the 2012 Masters to Bubba Watson and the 2015 Open Championship to Zach Johnson.
Known for having one of the better swings in professional golf, Louis can always compete if the putter gets hot. A bit older now, but don’t be surprised if you see his name on a major championship leaderboard again.
