"yikes" indicates an opinion on the subject!
Ashby threw 16 innings in Sept over 12 appearances and gave up 3 total runs. Walked 6. Struck out 19. Lowered his ERA on the season from 2.31 to 2.16 in the process.
Objectively he pitched well to very well to finish the season - so the "recent trend" you are referring to must only be his 4 1/3 innings pitched against the Cubs, which admittedly, wasn't his greatest 4 1/3 innings on the year. But I return to "sample size alert"... because it is what it is.
Not mad, just providing context. Go Crew.
