On his weekly Pirates mailbag video, Post-Gazette Pirates insider Noah Hiles answers reader questions. Among them: What are the reasons the Pirates' offense is struggling so profoundly. Is it a problem with GM Ben Cherington's development regime? Why does Henry Davis instead of Joey Bart catch for Paul Skenes starts? Could hitting coach Matt Hague be in trouble after manager Derek Shelton's firing? What should we expect from Spencer Horwitz when he returns from injury? Are there any updates on the search for a bench coach? Could Francisco Cervelli be a candidate? And how has Don Kelly performed in his first week as manager?
