The Indians made their first playoff appearance under Tris Speaker in 1920. Out of the six managers that have led the Indians into the postseason, only Speaker and Lou Boudreau have led the Indians to World Series championships, doing so in 1920 and 1948, respectively. Al López (1954), Mike Hargrove (1995 and 1997) and Terry Francona (2016) have also appeared in World Series with the Indians. The highest winning percentage of any manager who managed at least one season was Lopez, with a percentage of .617. The lowest percentage was Johnny Lipon's .305 in 1971, although he managed for only 59 games. The lowest percentage of a manager with at least one season with the Indians was McAleer's .397 in 1901.
