The dominant storyline of this postseason is reliever usage — well, the dominant storyline aside from the length of championship droughts, at least. Cleveland manager Terry Francona has freed himself to use elite reliever Andrew Miller when necessary rather than constrain himself to such trivial guidelines as save opportunities. Miller’s success (and Francona’s resultant success) has led people to ask whether this is a watershed moment for standard relief pitcher usage. Has Francona made it acceptable to more closely align optimal reliever usage with leverage rather than inning?
There are a few big reasons to think Miller’s 2016 postseason isn’t going to change bullpens as we know them. First of all, Miller’s contract status makes him immune from the reality that relief pitcher’s earnings are intimately tied to save totals. Like it or not, save totals are of real consequence to relief pitchers who aren’t already receiving hefty salaries. Secondly, managers can do things in the postseason that simply aren’t practical during the 162-game regular-season grind. As an example, consider: even though Francona has utilized Miller in a notably flexible relief-ace role ever since Cleveland acquired him from the Yankees at the end of July, Miller also entered a game in the sixth inning or earlier just once in his 26 regular-season appearances. In the postseason, however, he’s entered in the sixth or early in four of his nine outings.
Perhaps the biggest reason, though, that Miller’s case is unlikely to cause any immediate radical changes in bullpen management, is one discussed by an aptly titled article at ESPN.com by Sam Miller: “Cody Allen makes the Andrew Miller experiment possible”. To avoid confusion (and the resultant mass hysteria) likely to be caused by their shared surname, we’ll refer to the illustrious writer as Sam, and continue referring to the pitcher as Miller. Sam rightfully points out that the mere existence of another elite reliever is what frees up Francona to utilize Miller in such unconventional ways.
“If there were no Andrew Miller, [Cody] Allen might be the talk of this postseason… But Miller’s brilliance has ensured that Allen’s brilliance has gone overlooked. The irony is that Allen’s brilliance had ensured that Miller’s brilliance has been possible.”
Although the ship has long since sailed on making Allen “the talk of this postseason”, we still can (and should) spend some time talking about the other elite reliever who’s helped to situate Cleveland one win away from their first championship in 68 years. Allen has pitched 11.2 innings this postseason — or, to put it another way, has recorded 35 outs. Of those 35 outs, 22 have been via the strikeout — giving him a positively obscene 17.0 K/9 rate. To put that in perspective, uber-reliever Miller is sporting a 15.4 K/9 this postseason and the only reliever ever to top 17.0 K/9 in a regular season is some guy named Aroldis Chapman, who reached 17.7 K/9 in 2014.
