The Z Files: Second-Half Bullpen and Basepath Observations
The Z Files: Second-Half Bullpen and Basepath Observations

This article is part of our The Z Files series.

There's about one month left in the season, so category management is paramount. A major issue when plotting strategy is knowing what you're working with, as many rosters have changed since, or even before, the trade deadline. Two prime examples are bullpens and team tendencies with regards to the running game. As such, today we're going to look at team bullpens since August 1 and stolen base data since the break.

Having a feel for how a bullpen is faring is important when selecting batters to use in a daily or even weekly format. Some of the ensuing numbers are due to a change in personnel; others are just relievers performing better or worse than previously. Even for an entire team, one month is a small sample in terms of innings, so there is some luck involved as well. Still, these numbers offer a starting point, then it's a matter of determining why the bullpen is performing the way it is and venturing one's best guess what will transpire down the stretch.

For comparison purposes, here is the bullpen data through July 31. Please note the tables are sortable.
