Dodgers catcher A.J. Ellis is the top game caller in the league, writes Harry Pavlidis for ESPN. In recent years, new data and techniques have allowed analysts to measure catcher framing skills. Pavlidis evaluated the various factors controlled by a catcher’s game calling and converted them into a runs saves statistic. Ellis draws negative reviews for the other aspects of his defensive game, but he’s credited with 38 game calling runs saved from 2012-2014. Rounding out the top five are Alex Avila, Yadier Molina, Derek Norris, and Ryan Hanigan.
