After a stretch of four straight missed cuts, Creamer fell outside the top 40 in the world rankings by September 2015; she was dealing with the effects of swing and equipment changes. Despite not qualifying on points for the 2015 Solheim Cup team, Creamer was chosen for her sixth appearance in the event as a captain's pick. As part of a U.S. comeback from a 10–6 deficit entering the final session, she contributed the Cup-clinching point with a win in her singles match. For the 2015 season, her earnings were under $400,000, 47th on tour.
