For the 2015 Solheim Cup at Golf Club St. Leon-Rot, Germany, Sörenstam again was appointed an assistant captain by a Swedish European Team captain, this time Carin Koch. Two controversies with Sörenstam involved, given a lot of public attention, occurred during the match. The second day afternoon four-ball match between Suzann Pettersen and Charley Hull for Europe against Alison Lee and Brittany Lincicome, United States, was all square, when Lee missed a putt to win the 17th hole. Taking for granted that the next 18-inch putt was conceded, Lee picked up her ball. However, Pettersen pointed out that it was not conceded, and the Europeans won the hole. Koch and Sörenstam tried to convince Pettersen to change her mind and concede the putt, but as it was a fact that Lee had picked up her ball without the putt being given to her, it was not a possibility within the rules of golf, for the players to agree on the outcome of the hole and change the sequence of events afterwards. Pettersen/Hull eventually won the match.
