Probably. Nicklaus won 18 majors. Tiger has won 15 majors. He is 43 years old. In seven years he becomes a senior golfer so he has to win four majors in the next seven years. Four out of 28 that will be played.
There are four majors each year: the Masters Tournament, the U.S. Open, The Open Championship and the PGA Championship. The odds of Tiger winning depends on two things. Tiger and the competitors. There’s plenty of time and Tiger is playing great again but winning four more majors is an uphill battle.
