1. John Russell
Russell has been Showalter’s bench coach since the middle of the 2011 season, and prior to that he was manager of the Pittsburgh Pirates from 2008-2010 with a 186-299 record.
But Russell had far greater success as a minor league manager, first in the Minnesota Twins’ organization with five winning seasons in eight years (and being named Minor League Manager of the Year by Baseball America in 2002). Later, he was named International League Manager of the Year in 2006 as manager of the Philadelphia Phillies’ Triple-A affiliate. After one more season managing Philadelphia’s Triple-A team, Russell moved on to become the Pirates’ manager.
Assuming Showalter’s coaching staff is cleaned out, Russell will be officially gone soon too. But a new lead executive would do well to circle back to him for an interview. Russell’s second chance to be a big league manager may come soon regardless, due to a long connection to Showalter and his own past success as a manager in the minors.
