Who Is Louis Oosthuizen's Caddie?

South African Louis Oosthuizen has had several different people carry his bag throughout his career so far but who is his current caddie? Below we have taken a look.

Who Is Louis Oosthuizen's Caddie?

Louis Oosthuizen's current caddie seems to be an ever-changing situation at the moment. For a lot of 2020 he had Greg Hearmon on the bag but Glen Murray also was seen looping for him, for example at the 2021 WGC-Dell Technologies Matchplay.

A man called Colin Byrne was also on the bag for several weeks before that at The Players Championship and a couple of other events as well.

However for the 2021 Masters Oosthuizen brought Bryan Drennon into his team. We do not know that much about Drennon but we know he caddied for Chinese amateur Cheng Jin at the 2016 Masters.

Additionally the South African had been working with Phil Lowe for a while. Some of the other players Lowe has worked with in the past include Brendon de Jonge and Moriya Jutanugarn.

Oosthuizen has also worked with Wynand Stander on and off for a long period too; for example the pair worked together as recently as the 2021 PGA Championship. That is a lot of caddies, but at the moment Byrne seems to have the job on a permanent basis. 

Byrne has worked with Rafa Cabrera Bello, Ernie Els, Retief Goosen, Edoardo Molinari and Alex Noren before and he cites his greatest caddying memory as winning the 2004 US Open at Shinnecock Hills with Goosen.

At the start of his career, Oosthuizen used a man called Zacharia Rasego as his caddie. In fact it was Rasego who was his caddie during his Major victory at the 2010 Open. What made this even more interesting was that before the tournament began, Rasego was told that their player-caddie relationship would end after the week at St Andrews. But because they won, the relationship stayed on for a bit longer.
