At the end of the day, Daniel Mengden's 2016 has been a rousing success. He breezed through two levels, finding himself in the bigs just a year after being acquired in the Scott Kazmir trade. While his transition to the big leagues hasn't exactly been seamless, Mengden's mastery of the minors is an objective success.
Mengden's big league struggles are fine and mildly expected, especially when the guy we're discussing was pitching in the California League just a year ago. But it still presents some questions, too. Is Mengden just learning the ropes, or should we have long term concern about his viability?
