With rounds of 69-63-67, carried a three-stroke lead over playing partner Rory McIlroy into the final round of the BMW South African Open. Lost the lead with a three-putt on the 14th hole – marking his first bogey since the first round. A subsequent bogey by McIlroy on the 17th hole deadlocked the two players, with Storm (who closed with a 1-under 71) going on to par the third extra hole at the Glendower GC in Johannesburg for the second European Tour victory of his career.
2014: Shot four rounds in the 60s at the Omega European Masters (64-66-64-68) and finished regulation at Crans-sur-Sierre GC tied with David Lipsky. In the sudden-death playoff, made a bogey to Lipsky's par to finish solo second. 2007: Came from five strokes back entering the final round in early July to win the French Open on the European Tour. It was his first European Tour title.
