Left-hander Ricky Tiedemann, who MLB Pipeline rates as the No. 1 prospect in the Blue Jays’ organization, needs Tommy John surgery, Toronto manager John Schneider told reporters Saturday.
Tiedemann is set to undergo the procedure on Tuesday after meeting with Dr. Keith Meister and Dr. Neal ElAttrache. It is expected that Tiedemann will miss 12 to 14 months, meaning that his 2025 season is also at risk.
Injuries have hampered Tiedemann all season, with ulnar nerve inflammation in his left elbow landing him on the seven-day injured list back in April before left forearm tightness put him on the shelf earlier this month.
Tiedemann, 21, has cruised through the Blue Jays’ farm system this season, starting the year with Toronto’s affiliate in the rookie-level Florida Complex League before moving on to Class-A Dunedin and Triple-A Buffalo.
In eight starts across those three levels of the minors, Tiedemann went 0-1 with a 5.19 ERA.
The Blue Jays selected Tiedemann in the third round of the 2021 draft.
