SCOTTSDALE, Ariz. (AP) – Ryan Braun understands why many people are skeptical of him, given the way his name has twice been linked to performance-enhancing drugs.  He refuses to let it bother him.  On a sun-splashed field in Arizona on Wednesday, the Brewers slugger said that getting back to spring training has helped him deal with the swirling controversy, and that playing for the U.S. team in the World Baseball Classic could help to convince some fans to give him a clean slate.    “Obviously, there’s been a lot of things I’ve dealt with over the last year and a half,” he said, “but I’m just trying to focus on the things I can control.”
