Because the Masters did not exist until 1934, some credit Bobby Jones with such a feat given he won the Amateur Championship, which was held in Britain. However, after McIlroy's win, only six have completed the "modern" or "professional" career grand slam.

But finally, McIlroy has claimed his green jacket. It took him 72 holes plus a one-hole playoff against Justin Rose, it took him multiple collapses and resuscitations, but at last, McIlroy is a Masters champion, once again a major winner, and now one of the six men with a career grand slam, the first since Tiger Woods in 2000.
