A key to the new look middle infield for the Pirates, will be the play of Josh Harrison, who will be manning second base after the departure of home town legend Neil Walker. His ability to embrace the change and acclimate quickly should lead to an improved fielding team from the one in 2014 that certainly had fundamental issues, especially on the right side of the infield. (Ahhhem, Walker, and Pedro Alvarez)
Since breaking into the league in 2011, Harrison has started the position in 99 games, so it's not necessarily a place that he is all that familiar with.
