For four seasons after Jayson Werth departed Philadelphia via free agency, the Phillies had a depth crisis at the center field position. Their top four backups by playing time were John Mayberry Jr, Michael Martinez, Tony Gwynn Jr, and Cesar Hernandez. Of those four, Gwynn was a true center fielder, but the others represented varying degrees of defensive disasters at the position. This frustrating trend mercifully came to an end in 2015 when through either astonishing luck or masterful scouting (or, more likely, a beautiful marriage of both) the Phillies transformed a second baseman from Double-A named Odubel Herrera into a legitimate major league center fielder while the team’s former primary center fielder, Ben Revere, moved to left field as insurance.
