Vijay Singh
Singh was a good player in his 20s, but he became a great player in his 30s, and then a legendary player in his 40s. At 35, his win at the 1998 PGA Championship solidified his status as one of the game's elite players and he followed that up with a Masters victory in 2000. In 2004, at 41, he had one of the best seasons in golf history. Singh won nine times that year, including the PGA Championship, capturing the PGA Tour Player of the Year Award and taking over the top spot in the Official World Golf Ranking from Tiger Woods. In total, a record 22 of his 34 PGA Tour titles came after he turned 40. Singh became eligible for the Champions Tour in February 2013, but he plans to continue playing a full PGA Tour schedule for as long as possible. He finished runner-up in the opening event of the 2013-14 season.
