2023 Fantasy Outlook
A southpaw with a prototypical 6-foot-4, 220-pound frame, good athleticism and loud stuff, Tiedemann's ascent from the 91st overall pick in 2021 to one of the best pitching prospects alive was one of the storylines of the minors, especially in the first half of the season. He logged a 2.17 ERA, 0.88 WHIP and 117:30 K:BB in 78.2 innings during a three-level climb from Single-A to Double-A, all as a 19-year-old. The walk rate was a tad high at times, but hitters couldn't do much when they made contact (three HR with a .149 batting average against). His mid-90s fastball and low-80s slider project as plus pitches, while his mid-80s changeup is his best pitch and one of the best changeups in the minors. Pitching prospects often prove that development is not linear, but a first-half MLB debut is possible in 2023 if he picks up where he left off last season. Read Past Outlooks

Nearing throwing program
Blue Jays general manager Ross Atkins said Monday that Tiedemann (biceps) is expected to resume a throwing program next week, Ben Nicholson-Smith of Sportsnet.ca reports.
ANALYSIS
The talented young left-hander exited his May 4 start with Double-A New Hampshire due to left biceps inflammation, an injury which could be related to the left shoulder soreness he dealt with during spring training. Fortunately for Tiedemann, his setback doesn't appear to be an overly significant one, though he may be two weeks or more away from returning to game action while he works to ramp back up again.
