The best by a mile. His 45 career victories are 16 more than anyone else. As a senior, he remained the ultra-competitive grinder who won three U.S. Opens, but with the need for length reduced, the completeness of the rest of his game shone. Raymond Floyd said that he never saw a better putter in his life than Irwin after age 50. Irwin won a recording-tying nine times in 1997, and seven times the next year. He also won seven Champions Tour majors, including the 1997 PGA Seniors by 12 strokes. Irwin went 11 straight seasons with multiple victories, five more than anyone else. Although injuries have taken their toll, he's won three tournaments since turning 60.
