I think it's just their pitching progression development model now
Tiedemann was a 2021 draftee who threw 78.2 innings in 2022 across three levels (aggressive promotion to AA) and he was going 5 innings or at least 4 in most of those starts, until he hit AA.
King was a 2024 draftee who threw 61.2 innings in 2025, between the complex and A ball. They weren't as aggressive with him. Did not push his levels and did not push his innings.
Similar kind of stuff but RT would have been more polished right away (walk rate tells us that).
King being 19 for three more months, I bet they just want to see close to 100 healthy innings for him this year. Maybe not even that many. They probably regret pushing RT to AA back in 2022 and regret not building up his innings more deliberately.
There are not a lot of other Toronto data points. Here are all of the High School SP they drafted and signed after the RT draft:
Nolan Perry - had injury issues
Stanifer - wasn't very good in 2023, 2024 but they let him loose in 2025 at 21 years old when his talent broke through
Maroudis - got hurt in 2024
Carson Messina - elbow soreness took his whole season, will be on the FCL roster this year to start, huge helium potential if he has his velo still 🔥
Troy Guthrie
Johnny King
I think the youngest MLB SP who was a domestic draft pick was Elmer Rodriguez. He was a 2021 draftee. His progression:
2022: 38.1 innings, 2023: 55.1 innings injury (King is here), 2024: 89.2 innings, 2025: 150 innings
