I won't spend too much time on this. As frustrating as Hinch's platoons can be, the reality is he is one of the best managers in baseball. He's really good at playing chess with his decisions.
The only time I've really been upset with him with this season is when he kept running out Jose Cisnero in leverage situations when he clearly wasn't cut out for it. Cisnero has improved over the course of the year, but the fact he kept going to him in high-leverage situations when he was clearly struggling was just very frustrating.
Other than that, his bullpen management has been pretty spot on. Again, the platoons can be pretty annoying, but I think that's more of a Scott Harris thing than a Hinch thing. Hinch didn't platoon nearly as often before Harris got here.
Be thankful Hinch is still the Tigers manager. It could be so, so much worse.
