First of all, while I agree overall pitching strategies are almost certainly decided above Baldelli, I strongly doubt individual in-game pitching decisions are. Exactly if/when to remove pitchers, which relievers to use and exactly when. Etc etc.
So "we're of the belief we can get more effective starting pitching if we limit their exposure" comes from the FO, or a collaboration, "I'm taking my best guy out after 5 and less than 80 pitches" is 100 percent Baldelli. As was leaving Ryan in to get shelled the previous night. I wonder if one might be an overreaction to the other?
Using Duran last night, with a 6 run lead: Baldelli. 100 percent Baldelli. And I would imagine not a decision the FO would be pleased with, by the way.
Secondly, it's "some fans," not "fans," but more importantly it's pretty lazy analysis to constantly fall back on the "what do fans know" defense. Or set up two strawman sides to argue against.
Baldelli, by the way, will almost certainly get fired at some point. Like ?95? percent of all MLB managers. A few retire. The rest get canned. That's not a reasonable defense either.
Defend the decisions. That's what should be discussed.
