As many are aware, Fangraphs has "pitch value" stats. Homer's fastball is not very effective this season by this measure.

wFB uses linear weights to determine how many runs are saved by the use of the pitcher's fastball. Chapman, for example has saved 17.8 runs, Cueto 17.6 using the fastball.

Bailey's fastball, by this measure, has saved -14.1 runs.

Now, that stat may not be entirely fair because Homer has probably thrown many fastballs this year and it is a counting stat. So there's also a wFB/C stat which standardizes the results per 100 pitches. Chapman is +2.02 by that measure and Cueto is +1.20, again focused on the fastball.

Bailey's fastball, by this standardized measure, has saved -.95 runs.

Others may understand these stats better, but it seems to me that a power pitcher needs a more effective fastball and this could correlate to the relatively low K rate so far for Homer. I was surprised Homer's fastball did not grade out higher.
