Tiger Woods has withdrawn from The Open and is replaced by Marcus Fraser of Australia.
The multi-major winner recently underwent two back operations and stated that this year's open at Royal Troon has come to early in his recovery.
"I'm not quite there yet. I've pushed through a lot of injuries and rehabs before," said Woods.
"I just need to get to where strength-wise I can handle the workload of playing out here on a weekly basis, practising after rounds, not having to go ice my back and all that kind of stuff.
"I am trying to do it correctly at this time."
The next three competitors on the reserve list are as follows:
1st Reserve: Luke Donald, England
2nd Reserve: Daniel Summerhays, United States
3rd Reserve: Charles Howell III, United States
