Tim Wallach was named Pacific Coast League manager of the year in 2009, and he has coaching experience at the major league level.
Brad Ausmus had a very successful playing career as a Gold Glove-winning catcher, and he just managed Team Israel last month in the World Baseball Classic qualifier.
Luis Gonzalez is perhaps the biggest name of the four. He is a well-known World Series hero (from 2001), and hit 354 career home runs.
What do the four have in common? Berardino seems to think that the Marlins will want a candidate who is mild-mannered and well-respected around baseball. The next manager will be owner Jeffrey Loria's fifth since 2010.
