Showalter is entering his sixth season at the helm of the O’s and his .535 winning percentage is second only to his tenure with the Yankees, when he won at a .539 clip. His time with B-More has enabled him to now move almost 100 games over .500 for his managing career (1,259-1,161) for a fine .520 mark. It’s that pesky 9-13 postseason mark that haunts Showalter.
