The Braves are closing in on a deal with lefty reliever George Sherrill, tweets ESPN's Jerry Crasnick. Sherrill, 34 in April, was non-tendered by the Dodgers after a lost 2010 season. He's always been useful and sometimes dominant against lefties in his career. The Braves could be strong on the southpaw relief front, with Eric O'Flaherty and Jonny Venters already in the fold.
