The Holywood man is preparing for the tournament which starts tomorrow
Rory McIlroy says practice has been a little different this week as he gets ready for the start of the South Africa Open tomorrow.
It's being staged at significant altitude, just outside of Johannesburg.
McIlroy told Sky Sports News that he's been hitting it miles off the tee as a result.
The World Number Two player has also indicated to the BBC he is unlikely to compete at the next Olympics in Tokyo.
