I mean if he were to run the 102MPH heater out in the 8th, he would still need someone to pitch the 9th. Because Pagan blew the lead, there was no Bottom of the 9th. Now maybe Duran could pitch both the 8th and the 9th, but he’s only pitched multiple innings 7 times in 26 appearances this year. I don’t think it’s fair to criticize Baldelli for not counting on Duran to pitch two innings.
Also you do not know that Baldelli is a detriment to the Twins. Managers are not as big of a part of the equation in the modern game as you might think. There are many other coaches and personnel that all play a part. If you want to criticize him for the bullpen meltdowns, please consider the fact that he only has 2-3 reliable bullpen arms to work with. That’s not his fault.
