I'm not sure they used him in exactly a modern/scientific way in 2022
How many 19 year old pitchers, drafted the prior year out of high school, are routinely throwing 6+ innings and 90+ pitches?
Towards the end of 2022 Painter was routinely going 80+ pitches, with 90+ a couple of times.
The Phillies picked Mick Abel 15th in 2020. In 2021 he threw less than 50 innings, all at one level. Never threw 6 innings, never threw 80 pitches.
The Phils basically skipped an entire year with Painter. They had him and Abel, a year older, doing the same basic workload.
For comparison the Jays capped Tiedemann at 5 innings and in August they kind of shut him down, partially, and he finished the year with a few 3 inning outings.
