Charles's move to the Senior PGA Tour (now called PGA Tour Champions) was very lucrative and successful with 23 titles; and in three years 1988, 1989 and 1993, he recorded lowest scoring average. He finished second on the European Seniors Tour's 2007 Wentworth Senior Masters at the age of 71. He was the first left-hander to win a major, but also the first lefty to be inducted into the World Golf Hall of Fame, in the veterans category. He was inducted in 2008. He would remain the only lefty inducted into the World Golf Hall of Fame until Phil Mickelson was elected in 2011.
