Cubs: Miguel Montero plays 'psychologist' to get the most out of Jake Arrieta

Lost amid the craziness of Friday's game and David Ross' emotional sendoff was Miguel Montero locking up a spot on the Cubs' postseason roster. The Cubs don't have to get their National League Division Series 25-man roster until the morning of Oct. 7, Game 1. The veteran catcher has struggled to find consistency at the plate this season, but his work behind the plate has proven invaluable, especially with reigning NL Cy Young winner Jake Arrieta.
