If you have been following baseball the past few weeks, you know that MLB has some terrible managers. For example, Donnie Baseball called for consecutive sacrifice bunts. That is right, Mattingly gave his team two outs in an inning. If you don't follow baseball, there is only three outs in an inning.
While there is much screaming to the hilltops about poor managerial decisions, it is worth noting that Joe Maddon isn't the only savvy manager in MLB.
David Laurila has an excellent piece on Acta's 21st century managing.
