I found a site that tracks stats for a defined period and have been tracking plays where a team has a better Slugging % and better Bullpen Whip (at least .1 difference) over the last 20 days. These have been doing pretty well for the past 2 weeks so I will try posting them for awhile to see if I am on to something. Most of plays are favorites, which makes sense because you are usually on teams playing well as of late.
