Great summary. One thing not noted - even with Duran not being used much this month, Lopez 23.0 innings/25 games, 337 pitches/14.65 pitches per inning, Moran 23.0/20/401/17.43, Jax 22.1/24/387/17.33, Pagan 21.2/20/370/17.08, and Duran 21.1/20/324/15.19, all have about the same amount of innings, Lopez and Duran the most economical amount of pitches.
And no mention of what is the most important stat for a relief pitcher, at least for me, the true indicator of "relief" - inherited runners scored and the ratio.
