Offseason book 3 of 3 for coaches. One Last Strike by former St. Louis Cardinals manager Tony La Russa. Baseball, unlike a lot of other sports, is a daily grind filled with a lot more failure than success. La Russa addresses the psychology involved in managing a baseball team of different personalities thru 6 months of competition - building and maintaining team unity thru slumps and clubhouse conflict, resiliency, and accountability.
