The Arizona Baserunning Juggernaut
Since the start of the 2015 season, the Diamondbacks have been easily baseball’s best baserunning team. They’ve been baseball’s best baserunning team in terms of stolen bases, and they’ve been baseball’s best baserunning team in terms of other kinds of advances. Baserunning isn’t one of those components that makes or breaks a roster, given that it’s more peripheral or secondary than anything else, but the longer something like this goes on, the easier it is to recognize.
In this very season, the Diamondbacks are at it again. That’s the second-place Diamondbacks, the wild-card-spot-occupying Diamondbacks. A few years ago, by our numbers, as a team they were 13 runs better than average on the bases. Last season, they were 18 runs better than average. This season, they’ve already been about 12 runs better than average. They didn’t do anything noteworthy on this particular afternoon, but that’s what a team gets for facing Max Scherzer. The team’s still been elite, and they’ve played only 30 games.
