Born Lodewicus Theodoris Oosthuizen, he secured his place in the history books with a victory in the 2010 Open Championship at St. Andrews. His seven-stroke win placed him alongside South Africans Bobby Locke, Gary Player and Ernie Els as Open Champions. It was only his ninth appearance in a major championship and his Open success came only four months after his European Tour breakthrough, his victory in the Open de Andalucia de Golf.
Born in the town of Mossel Bay, a small community about 34 miles east of Cape Town. Comes from a family that tends a farm back. His father and brother were great tennis players, but Louis opted to play golf. Grew up alongside Charl Schwartzel and the two won the World Junior team Championship in 2000. At the age of 17 in 1999, got his big break when he was given one of the first memberships in the Ernie Els Foundation, whose sole purpose was to identify talented young South African players and give them the resources to get better in golf and provide educational and life-skill assistance. At this stage of his life things were very expensive and he doubted that his father would have been able to absorb the expense if he wasn't a part of the foundation. Not only were the financial concerns taken away but Oosthuizen related how important it was that Els attended some of the clinics and spent time with the boys and became a mentor for Oosthuizen and Schwartzel.
Turned professional in 2002 and played on the South African tour, then joined the European Tour in 2004. He won for the first time in South Africa at the 2004 Vodacom Origins of Golf Tour and then the 2007 Dimension Data and the Telkom PGA Championship. Struggled on the European Tour his first five years and didn't make any real progress until 2009 when he had runner-up finishes in Abu Dhabi and then the Qatar Masters. Got into the winners circle in March of 2010 when he won the Open de Andalucia, which got him into a totally different level in the golfing world. That win, along with a runner-up finish the week before in Morocco, pushed him into the top 50 of the world rankings on the closing week to get into the Masters. He was able to hold on to a spot in the top 50 to play in both the U.S. Open and The Open Championship.
For those still stuck, there are two ways to pronounce his name, first probably the way they do it in South Africa, WUHST-Hyzen and another over in Europe, OOST-hou-sen.
