Having a "go-to closer" is simply not the element now that it was even 3 years ago. Analytics driven decision makers now understand that putting relievers in the best position to succeed is more advantageous than having defined roles by inning.That is a misleading point. Having a go to closer allows the manager to mix and match his pitchers and shuffle them around depending on the situation—ex. Right lefty etc. Also it puts less pressure on the pen because rolls become more defined and pitchers get more comfortable with their roll. Don’t undervalue that ball players are creatures of habit and will perform better in situation where they feel the most comfortable and confident.
Many times this can come in the ninth inning, but if the opponents best hitters are up in the eighth of a close game, managers (including Cora) will try to use the most effective match ... rather than having a "go to closer" face weaker batters in the ninth.
Joe Dokes and Red(s)Hawks are on point here.
