It's hard to read much into the stats from a 60-game season. Heck, it's hard enough to make much of bullpen stats to begin with. With that small of a sample (especially with 7-inning games also in the mix), the inflated numbers include guys who were only on the team for two weeks, as well as guys who stunk early but got better (including a few of the youngsters and even Hector). Conversely of course, they lost Alvarez, and Romero got worse instead of better (but in a normal season who knows what another 100 games would have brought), and all the trade acquisitions were terrible.
Anyway, what happened happened, the stats don't lie, but they also don't project. Especially with five or six guys definitely gone.
I'd still bring back Parker again if possible (not guaranteed)
