Campbell had no top-10 finishes on the European Tour between 2009 and September 2012, although his U.S. Open win meant he retained his playing rights. In 2012 he moved first to Switzerland and then to southern Spain, where he has since been the brand ambassador for a golf resort and opened a golf academy. In October 2012, he finished third in the Portugal Masters, and in December he finished 8th in the Hong Kong Open (both European tour events). He retired from golf in 2015, citing an ankle injury and personal issues.
