Toronto Blue Jays manager John Schneider said Friday that top prospect Ricky Tiedemann has ulnar nerve inflammation and not a tear in his elbow.
Tiedemann could return to throwing in a week to 10 days.
The 21-year-old lefty has made three starts with triple-A Buffalo this season and has a 5.63 ERA and 10 strikeouts over eight innings.
Tiedemann was the Blue Jays’ third-round pick in 2021 and has since become the most highly touted prospect in Toronto’s ranks.
He spent most of the 2023 season in double-A New Hampshire, where he posted a 5.06 ERA and 58 strikeouts in 32 innings pitched.
Tiedemann ranks 26th overall in MLB’s top prospect rankings, and first overall for the Blue Jays.
