Sure, but you are only going to lose.
This is from Wikipedia (which I thought had the most succinct description):
The Grand Slam in men's golf is an unofficial concept, having changed over time. In the modern era, The Grand Slam is generally considered to be winning all four of golf's major championships in the same calendar year. Before The Masters was founded, the national amateur championships of the U.S and the UK were considered majors along with the two national opens and only Bobby Jones has ever completed a grand slam with these. No man has ever achieved a modern grand slam, Tiger Woods being the closest in winning all four consecutively, but over two calendar years.
What Tiger and others have is considered a career Grand Slam (that is, winning each of the four majors during their career). But that is not the nature of a true Grand Slam, winning each of the major championships in the same calendar year.
Sorry. Maybe he will do it this year. The Masters is less than two weeks away.
