Tiedemann’s fantastic first professional season has come to an end due to hitting his pitch limit.
Per TSN’s Scott Mitchell, the 20-year-old lefty won’t pitch again in the 2022 season per his sources. 
I figured as much, as he was added to the Development List (which can be used to limit innings among other purposes) for the second time back on August 28th. With only two more Fisher Cats series that he’d be eligible for, it seemed unlikely that the 91st overall pick from the 2021 draft would pitch again.
It can’t be understated how incredible Tiedemann pitched this season. With the Dunedin Blue Jays, he posted a 1.80 ERA and 2.07 FIP in 30 innings pitched, with a 44.5 K%. He continued his dominance as a 19-year-old in High A, where he posted a 2.39 ERA and 2.92 FIP in 37.2 innings pitched.

Not just that, but he absolutely dominated in his first five starts, posting a 0.38 ERA and 1.72 in 23.2 innings pitched with an absurd 38.9 K%. Per Baseball Reference, he was -4.2 years younger than the average pitcher at the level  (-3 years younger in Dunedin). Tiedemann faltered in his next three starts, but it was already clear that High A was perhaps too easy for the 19-year-old.
He made his Double A debut as a 19-year-old, Eury Perez being the only pitcher younger than him to pitch 10+ innings. In 11 innings, Tiedemann posted a 2.45 ERA and 2.24 FIP with a 34.1 K%. Again, he recently turned 20 and was -5.5 years younger than the average pitcher in Double A.
So with the season recap out of the way, what is next for the 20-year-old? Next season, the lefty will have to be stretched out for a full season. Despite pitching like an absolute madman all season, Tiedemann didn’t register a quality start, despite only giving up more than three earned runs twice.

This is not atypical of a recently drafted college pitcher in their first season, as the workload in university ball, or junior college ball in Tiedemann’s case, is tiny compared to the pro season. Limiting Tiedemann to just 78.2 innings pitched made complete sense not to burn him out.
Tiedemann will definitely start 2023 in Double A with the Fisher Cats. If he continues to dominate at that level, Triple A is the next challenge for the lefty. I’d say Tiedemann pitching in Buffalo is a good possibility.
After that, it’d be on to Toronto. If he can dominate Double A, as well as Triple A, it wouldn’t be surprising to me if Tiedemann gets the call-up in August or September to the big league team if they’re contending. I’d assume that Tiedemann would pitch out of the bullpen, sort of like David Price in 2008.

Either way, the Jays have a lefty with the ceiling of a multiple Cy Young winner. Perhaps even better than Manoah. Tiedemann’s first season proved that.
