I think Folty is a unique case. He really only had one good season. His whiff rate percentile dropped to bottom 3%! His FB spin rate was 70% percentile in 2018, but dropped to 25% this season. If everyone else dropped at a similar rate, he'd still be closer to 70th percentile. It's the percentile drop that stands out. Maybe he was using spider tack in 2018. Why did he drop off in 2019? Did he stop using it then? When you look at statcast, he's a well below average pitcher for every season but 2018. Sometimes guys just have one good season and disappear. I think that's what happened to Folty. I'm not sure I'd even want him wasting a AAA spot.
