In his weekly Pirates mailbag podcast, Post-Gazette insider Noah Hiles answers reader questions. Among them: Why is Bubba Chandler, whom the Pirates will call up this weekend, starting in a long-relief role out of the bullpen rather than as a starting pitcher? Did the team move pitcher Andrew Heaney to the bullpen so he wouldn't reach his contract's innings bonus? Would the Pirates really be better if owner Bob Nutting had hired now-Milwaukee Brewers general manager Matt Arnold instead of Ben Cherington? Could Andrew McCutchen see some action at first base? And should the Pirates approach Konnor Griffin with a long-term deal offer before he gets too expensive? Noah answers those questions and more.
