Ellsbury first came up in the 2007 season when he was called up in June of 2007 and would make the starting lineup and would help the Red Sox win the World Series where he batted .438.
Glen Perkins is one of the rare players who can say that he played all 12 of his seasons in Major League Baseball for one team and from 2006 to 2017 he did exactly that as a member of the Minnesota Twins.
