It is often said that closers are made, not born. Any experienced baseball fan knows this; it seems that for every Huston Street type who arrives with hype, four or five Jason Grillis, Andrew Baileys, or John Axfords slip into dominance after finding dead-ends in other roles. As such, predicting who will ascend to MLB closer roles (beyond the obvious “the best MLB non-closer relief pitchers”) is often a fool’s errand.
This becomes even more difficult when one attempts to find future closers in the minor leagues. Many of the pitchers who end up closing MLB games were starters all through their minor league careers, but it’s tough to project a minor league starter as a closer outright–in doing so, one is essentially saying “This pitcher will fail badly at the role he’s currently in and subsequently find tremendous success in a role he’s never pitched in.” Certainly plausible, but not something that seems like it can be said with much confidence. And minor league relievers–well, they’re equally problematic to forecast. After all, if a pitcher has a big future, why isn’t he able to crack a minor league rotation?
It’s certainly possible to envision any number of minor leaguers closing out ballgames–as so many sabermetricians are fond of saying, the role of garnering save totals can be accomplished reasonably effectively by any number of players, and the minor leagues have no shortage of interesting power pitchers that could fit a closer profile if things go their way. However, it’s quite another thing to actually predict that a minor league pitcher will end up amassing saves in the big leagues.
I think White Sox pitching prospect Daniel Webb merits such a prediction, though.
