Anna Nordqvist has ended her ambassadorship deal with Saudi oil company Aramco.
The three-time major champion told the Swedish news agency TT in an interview that she received harsh criticism for the partnership.
"It didn't really turn out the way I thought it would," Nordqvist said. "I need to think about myself and I haven't felt good about this."
Nordqvist added: "I wasn't really prepared to get such an incredible amount of hatred and mean comments from people who don't even know me."
Aramco is owned by the Saudi Arabian government, which has recently invested billions of dollars in sports.
