I dont think he can. He's always had a quirky swing that relied a lot on hand-eye co-ordination. When its on he's one of the the best ball strikers in the world but he can easily get off. His putting is also up there with Sergio's - bad

Id hazard a guess someone like Howell or Stenson will be the next euros to win a major unless Sergio finally learns how to putt and keep his head for 4 days
