We know the hard core analytics teams are furiously developing an algo and data set to tell them when to shift an outfielder into the position that the shifted infielder has been occupying back on the grass. Calculate the outcomes probability distribution for each batter in various game situations. We will certainly see PAs with no left fielder and an outfielder back on the grass between 1st and 2nd. It will be interesting to see which teams do what and when, and how things evolve as the season goes along. I wonder if/how they can feed the positioning info based on current game situation to the manager in real time.
