GLENDALE, Ariz. -- The Dodgers will be doing their part to fuel one of the hotter trends in baseball, blurring the lines in their bullpen.Kenley Jansen retains the title of closer, but Brian Wilson will get opportunities to close, his traditional role. There might even come a day when Chris Perez or, gulp, even Brandon League pitches in a save situation. Both have done it dozens of times in their careers. Stockpiling closers wasn't by accident.
