But there is one trophy both of them are still desperate to add to their cabinets.
The duo tee it up at this week's South African Open hosted by the City of Johannesburg both looking for a first win at their home Open at Randpark Golf Club.
Oosthuizen is playing the event for the first time since 2010 and after three top tens, a victory would see him join Bobby Locke, Gary Player, Bob Charles, Ernie Els and Henrik Stenson as players to win the South African Open and The Open Championship.
“To have won The Open and the SA Open would be very special,” he said.

“I’m very happy the schedule has changed to allow me to play the SA Open. To be able to play this and Leopard Creek is what I used to do when I started as a pro. Those were two events I loved to play and I’m really looking forward to these two weeks.
“My game’s good, it’s trending in the direction I want it to be. There’s still a lot of work to be done to really be where I want it to be but I’ve been doing a lot of different things with my coach and just getting a feel for a few more things.
“I drove it pretty well at the Nedbank Golf Challenge. The putting was good. Iron play can improve but, all in all, it’s going in the direction I want it to go.
“This is a tough week with 240 players. It’s all on how you start, how you get out of the blocks on Thursday and Friday. We all know the cut’s going to be really low, so you can’t really cruise from the start."
Schwartzel has six top fives in this event and while he feels his game is in good shape, he is looking for that one week when it all comes together.
“It’s nice for me to be back,” he said. “I’ve had a really difficult year but my game actually feels as good as it’s ever felt. So maybe for me to come and play back home is something that I’m looking forward to.
“I’m obviously lacking a little bit of confidence but my game is in great shape. Playing in South Africa has always been good to me, so I’m hoping for some more of the same.
“My game is four good rounds from staying in great shape. There always seem to be two good ones or three good ones and then somewhere along the line I struggle. It’s difficult for me to put my finger on what’s going on.
“I know I’m playing definitely as well as I’ve ever played - if not better. On the range it’s great, in practice rounds it’s great.
“Everything I’m doing, the way I’m hitting the ball, the control I’ve got is really good. But then you’ve got this little thing called golf where you’ve got to put a score on the board and you’re judged on the results.”
