Sunesson was born into a golfing family. At age 15, she played golf at amateur standard, and decided to get an insight on the tour by persuading tour player Jaime Gonzalez to let her caddie for him in 1986.
Faldo, who had recently undergone major swing surgery with coach David Leadbetter, would win four majors together with Sunesson over a nine-year period. Sunesson decided to part from Faldo in 1999 to caddie for Sergio Garcia in what was a short-lived stint of just eight tournaments before being sacked after a run of poor form culminated in Garcia missing the cut in The Players Championship.
