Since March 1994, back injuries have affected Couples' career. His swing features an extreme shoulder turn at the top, which, combined with the fact that he keeps his left foot flat on the ground throughout the backswing, puts a lot of pressure on his lower back. However, with an abbreviated schedule, Couples is still one of the best players on Tour. In 2003, at age 44, Couples finished 34th on the PGA Tour money list. That year he also won the Shell Houston Open, his first win in five years; Couples wept with joy after the win, but quickly explained the tears, saying: "I'm always emotional when nice things happen to nice people."
