10Robert Allenby, Career Earnings: $26,762,583
Since turning pro in 1992, Allenby has won four PGA tournaments, accumulated more than $26 million in career earnings and represented the International Team in four Presidents Cups. In 2005, he also become the first golfer to win the triple crown of the Australian Masters, Australian PGA and Australian Open
in the same year. Yet despite all of his successes - both in the United States and internationally - the career-defining major has continued to elude him. The closest he's ever come was a seventh place finish at the U.S. Open in 2004. At 42 years old, the Australian's chances of winning a major are looking slimmer all the time, as he hasn't won a professional tournament in 11 years.
