As Yankees fans, we’ve been privileged to watch some stellar bullpen work in our lifetimes. Older fans (no offense!) can go back to Sparky Lyle, Goose Gossage, and Dave Righetti. More recently you have Mariano Rivera, David Robertson, and, of course, Dellin Betances and Andrew Miller. In less than two weeks Aroldis Chapman will join that group.
Even with all those great bullpeners, I don’t think we’ve ever seen two relievers — either at the same time or in different years — as overwhelmingly dominant as Betances and Miller are right now.
