Louis Oosthuizen, known for one of golf's smoothest swings, discussed the origins of his technique during a recent interview. The South African major champion emphasized setup and posture as key elements from his early days. He credits timing and technique for generating power despite his smaller stature as a junior.
Louis Oosthuizen stands alongside Ernie Els, Fred Couples, Adam Scott, and Justin Rose as one of modern golf's premier smooth swingers. A major winner, he claimed the Claret Jug at St Andrews in 2010, prevailing by seven shots. He also secured three top-three finishes in the 2021 major season. Now competing on the LIV Golf circuit, Oosthuizen has not yet won a title there, but his swing remains fluid.
In a recent episode of GOLF's Warming Up, hosted by Dylan Dethier, Oosthuizen traced his swing's roots. He began working with a coach as a junior, focusing immediately on fundamentals. "From Day 1 when I started as a junior I went to a coach and he was great with setup and posture," Oosthuizen said. "Those were always the things we worked on and everything was always close to square."
These basics, he explained, compensate for physical limitations and enable efficient power generation. As a small youth lacking strength, his swing was initially loopy with an over-swing. Over time, added strength allowed better control. When asked about his power source, he replied, "Timing and good technique." He added, "At a young age, because I was tiny, I didn’t have any power so I was very loopy, I had a long over-swing, and through the years when I got a little stronger, I could control that. But it’s always been aiming pretty square, just left of target, maybe, and working from an open position. It was never really something I had to do in my swing to try and generate anything. It was always pretty decent timing."
Oosthuizen's insights highlight how solid fundamentals can elevate any golfer's game, improving contact and power without relying on sheer size. Consistent simulator results underscore his approach's effectiveness.
