We were reminded of reliever volatility again in recent days when Atlanta traded five players to the White Sox for Aaron Bummer. We saw 16 different middle relievers contribute seven or more wins over the course of the season, led by the 12 wins Colin Poche had in just 60.2 innings of work. There have been many articles written on the subject over the years ( sample, 1, sample 2, sample 3) and I even last touched on this subject in late September looking at how non-closing relievers were contributing to the success of many fantasy managers. Reliever volatility is an issue which has been in baseball for many years now and is unlikely to go away any time soon.
