2017 U.S. Open champion Sloane Stephens and former Wimbledon runner-up Eugenie Bouchard grace the pages of SI’s annual swimsuit issue this year. "I’ve always loved the beauty of the SI Swimsuit issue and thought it would be incredible to one day be a part of it. I honestly never thought I’d have the opportunity," Stephens, who is making her first appearance in the issue, said. "When the opportunity was presented, I immediately said yes because I felt really honored to be a part of it."
