Though regarded as a plus (and, at times, elite) defender, Barney has struggled to deliver value from the offensive side. After averaging a barely serviceable .265/.306/.354 slash over 2011-12, Barney has slipped to a combined .214/.266/.311 line since the start of 2013. He has also contributed on the basepaths, but certainly was not doing enough to merit a starting role; indeed, he has graded out as barely above replacement level over the past two seasons.
The move’s immediate purpose is to clear roster space for the activation of Emilio Bonifacio. In the grand scheme of things, however, it represents yet another step towards the infusion of the Cubs’ top prospects into the MLB roster. Since being promoted when Barney went on paternity leave, Arismendy Alcantara has taken the lion’s share of time at second (though he’s playing center field tonight), with fellow top youngster Javier Baez reportedly also moving to that spot at Triple-A in recent days.
