The 2018 season was, of course, a historical one for the Red Sox that by and large will be remembered for the sheer dominance involved. If their playoff run is going to have a legacy beyond that in ten, twenty, thirty years it is likely going to revolve around “the rover” strategy. This is the name given to the plan of using starting pitchers in the bullpen to record important, late-game outs on their days off. We saw it throughout last October’s run and it was one of the majors reasons they were able to outlast every other team.
