Question: has tiger woods ever won all 4 majors in one year

Answer: No, Only Bobby Jones has ever completed a Grand Slam. No man has ever achieved a modern era Grand Slam. Tiger Woods won all four major events consecutively within a 365-day period, but his victories were spread over two calendar years (winning three events in 2000 and the Masters in 2001). The term also refers to a former tour tournament, the PGA Grand Slam of Golf, an annual off-season tournament (that was cancelled after the 2014 tournament) contested by the winners of the four major championships.
